all right this is gonna be a fun review so ladies gentlemen this here is LG's first 240 Hertz one millisecond response time IPS gaming monitor up until now I've been stuck on a measly peasant 144 Hertz monitor back at home so this is actually gonna be the first time that I'm gonna be trying out at 240 Hertz monitor so a couple days ago I went on my Twitter account to find out what refresh rate monitors you guys are using and to my surprise there's still a lot of people stuck on 60 Hertz displays what was more interesting however is that a lot of people have already jumped over to 144 Hertz and a small percentage has already leaped straight to 240 Hertz so yeah I'm kind of curious but mostly excited to see what the difference is like switching over from 144 Hertz to a 240 Hertz monitor I want to know if there's a noticeable difference and is it even worth upgrading but before we get into that let's review the monitor
stop paying full price for Windows 10 CD Keys you guys you can pick one up for your CD key comm just make sure to use my code to get that extra 20% off links in the description so the design of the g-9 750 stays true to LG's ultra geared gaming lineup we got super thin three sided bezels an aggressive triangular base design with red accents all around nothing really new here the construction of a stand is made out of all plastic and it's not as
sturdy as I expected there's definitely lots of play at medium height however if you raise the moderate to the top it becomes more noticeable the standards give you a good amount of height adjustability as well as tilt however you don't get any swivel adjustment you can also rotate the monitor a full 90 degrees but you can only do this in one direction however you can dish to stand all together and mount it since it is basic compatible as well the monitor comes with an
HDMI display port and a USB pass-through cable as well as a hook to help out with cable management and back you also get a good amount of port selection in the back a couple of HDMI a single DisplayPort you get your USB pass-through and two additional USB 3 ports accessing the menu is done through a joystick located on the bottom of the monitor and through here you have access to the adaptive sync option and black stabilizer which basically adjusts the
black saturation levels to make dark images stand out better in dark scenes you know before all this gaming IPS monitor hype gamers used to use TN panels to achieve their super high refresh rates and we all know the cons of TN panels subpar color reproduction and horrible viewing angles but that doesn't seem to be the case anymore because now looking at the best of both worlds we're starting to see a lot of high refresh rate IPS gain monitors being released in the market and this one from LG is no exception excellent viewing angles with incredible vivid
colors that makes every scene pop I mean the color reproduction on here is among the best I've seen in other similar spec monitors so on every monitor video I do on the channel I always test these four things white saturation black levels motion blur and of course the backlight bleed test and the LG monitor past most of them with flying colors we got great white saturation levels for the black level test all squares from top to bottom are distinguishable and this is with factory settings by the way I didn't find any ghosting or Corona artifacts present for the motion
blur test however there is some backlight bleed in the corners more specifically on the top-left corner which is definitely noticeable during dark scenes when it comes to color accuracy the monitor excels in srgb covering a hundred percent of its color gamut but only covers 78% of Adobe RGB so if you're a content creator and you use the sRGB color space then this monitor would be great for color sensitive work however if you're a professional working with Adobe RGB color space then you will need to find another monitor all right so let's hook this up
tomorrow warfare and see if I can tell the difference all right let's do this so before I actually launch the game I want to switch back down to 144 Hertz just so I can the difference switching back to 240 so there we go so now we run 144 Hertz let's launch the game and see the difference all right let's do this by the way if you guys play model over as well feel free to add me in-game I'll drop my gamertag somewhere on the screen so I bet it definitely tell us it's under 44 Hertz
oh nice try oh okay sounds up here yeah that's how you clear a house baby alright so I think I had enough 144 Hertz let's switch this to 240 still like okay whoa okay immediately I noticed how snappy it is our response of everything is oh yeah it's definitely noticeable Wow yes so I can definitely say this that I'm really bad at aiming another thing I can say is that the difference let me go is go first and then oh that was so bad anyways what I'm trying to say is the difference is not as noticeable switching from 60 244 but you can definitely tell like it's still it is still more
stable one thing I've also noticed is that my aim is slightly more accurate like I can almost tell where the krauser is gonna land if I can use an analogy I guess I would say this lets say all these years you've been using rubber right and let's say rubber is 144 Hertz in this example I mean it still feels good and you still have a good time and gets the job done and you'll be satisfied because it feels good to play on a higher refresh rate monitor and then you switch over to 240
Hertz the rubber comes off now it feels amazing things are more sensitive you're lasting longer because you're a better gamer and you're not dying as quick and of course you're getting more kills you might even keep playing after your match is done because that's how great it feels that's what it feels like playing on a 240 Hertz monitor so should you buy a 240 Hertz monitor specifically the lg monitor well if you have the money and this is very important by the way if
you have a capable PC of pushing around 240 FPS consistently then I say making the jump is absolutely worth it but if you're stuck on 60 Hertz and you don't necessarily have the money to burn then honestly I would just say pick up 144 s monitor and call it a day that is gonna be more than enough to keep you satisfied I feel like the 240 Hertz tier are for people who want the absolute best gaming experience no matter the cost but whatever you do please take this advice
don't buy any high refresh rate monitors if your PC can't handle it I've seen this so many times where people are using budget pcs that barely push 60 FPS on minesweeper and their gaming 144 monitors don't be that guy as far as the LG monitor it's a shame about the backlight bleed and the quality of the stand but overall I think it's a monitor and this is all I see the best you can get right now in the market in terms of specs 240 or is panel one little second response time
IPS g-sync color accuracy all that stuff this is currently the best in the market at least until three hundred hertz panels start coming out but honestly if you don't care about you know the viewing angles and the color accuracy all that nonsense you can buy a cheaper 240 Hertz monitor on a TN panel ultimately it comes down to how much you're willing to spend to get that gaming experience you've always wanted I'll drop a link to the monitor
down below.
the LG 27 GN 750 which is one that I was particularly excited to receive many people following our monitor reviews will be aware of the LG 27 gl 850 which was the first of LG's one-millisecond class IPS gaming displays now it couldn't actually hit a one millisecond greater great average with usable overdrive settings but thanks to LG's improvements to their IPS LCD technology it was still the fastest 1440p IPS display on the market and a great buy for gamers well the 27 GN 750 is using the same one millisecond class IPS technology but bringing
it to a new panel type instead of being found in a 27-inch 1440p 144 Hertz display the 27 GN 750 brings a one millisecond rated response time to a 27 inch 1080p 240 Hertz panel this gives us another option in the high end 1080p monitor market and one that thanks to IPS could be a really compelling buy it's not the first 1080p 240 hertz IPS monitor that I've reviewed though that goes to the msi ma g2 51 RX which is a smaller 24 inch design and uses a panel from a you Optronics and to be honest it performs really well easily offering fast enough response times to
keep up with the 240 Hertz refresh rate so LG has their work cut out for them to offer a great super high refresh experience here even with their known quality IPS technology aside from the main specs that we've been talking about LG offers a fairly typical experience here which includes g-sync compatibility aka adaptive sync so this monitor works flawlessly with both AMD and NVIDIA GPUs LG also touts HDR 10 support no Vaser display HDR certification here so this is a bit of a worthless inclusion that's mostly because this is just an sRGB display
99% according to LG's website but nevertheless unlike the 27 GL 850 it doesn't pack in a wide gamut the 27 GN 750 is also priced quite competitively which is typical of LG's current monitor lineup this makes it cheaper than the viewsonic XG 270 and Acer XV 273 X and around the same price as the suit is attractive VG - 7 9qm which I'm hoping to review soon LG isn't in the outright lead here in terms of price but luckily there are no red flags popping up just yet as for the design LG is sticking with their tried-and-true formula / they've been using
throughout their ultra gear line for the last few years I quite like it from a visual standpoint it's not the most premium construction is what you're getting is mostly plastic but I think the simplistic black aesthetic with a few red highlights looks quite nice nothing crazy going on here the focus is purely on that IPS display with decently slim bezels there are some neat features here including height tilt and pivot support Plus very easily accessible ports on the rear LG
doesn't tuck these away behind a plastic flap or along the bottom they're just straight on the back and easy to access to HDMI and DisplayPort here plus a USB hub and audio output no built-in speakers here my only real concern with the design is the stand is a bit wobbly for my liking nothing outrageous but the connection between the stand pillar and the legs isn't great so it does have the opportunity to rock around slightly a non-issue if you're not touching the monitor but it does feel a bit cheaper than I was expecting the on-screen display as with most
ultra gear monitors is controlled through a directional toggle along the bottom edge of the screen I quite like LG's OSD layout it's easy to navigate has all the relevant information viewable at a glance there aren't a ton of crazy features in here there's if you cross hairs black modes and so on but it's quick and it's well put together one question that tends to pop up when reviewing high refresh monitors like this is do you really need 240 Hertz and is it an upgrade over 144 Hertz well having reviewed a few 240 Hertz monitors lately I'm becoming more
accustomed to the improvements in clarity and motion handling the 240 Hertz provides over 144 Hertz so to me I'd say there is definitely improvement not as much as the gain from say 60 Hertz to 144 Hertz but playing games on a 240 Hertz display like this feels extremely responsive and you can even say the same for desktop applications of course in most circumstances you will need a powerful PC to hit 200 plus FPS at 1080p in many titles so make sure that you have a fast CPU in particular to avoid CPU bottlenecks to get the most out of this sort of monitor one
other thing to mention and I'm sure this has appeared in the comments is the pixel density of this monitor 27 inches of screen real estate but just a 1080p resolution isn't the highest resolution or sharpest experience going around and I tend to feel 27 inches is slightly too large for a 1080p monitor these days I tend to prefer more around that 24 to 25 inch size at this resolution it's not bad for gaming or anything like that especially when the refresh rate is so
high but for general desktop use like web browsing I feel the pixel density and resolution is a bit of a constraint now let's take a look at the all-important response time information starting with the four main / drive modes included at 240 Hertz the off mode does reveal quite decent stock response time numbers for this IPS panel with the 6.1 millisecond greater great average this is faster than a lot of IPS panels with overdrive so yeah we're off to a good start the normal
mode manages to improve performance quite nicely over the off mode with no appreciable increase to overshoot a 4.42 millisecond Greger average is good allowing for 82% of transitions to fall within a reasonable tolerance of the refresh window I think a lot of people will be happy with this mode but we can do one better using the fast mode we get a marginal improvement to a three point seven nine millisecond Greta great average still with no significant gains to overshoot so this is the best mode to use for high refresh 240 Hertz gaming with 95% of
transitions complying with the two refresh rate what we're left with is an IPS MOA that is truly capable of refreshing at 240 Hertz with a 1080p resolution like most of LG's recent one-millisecond class monitors they essentially cheat to list this as a one millisecond monitor I was able to achieve a 1.9 millisecond grader average using the faster overdrive mode with some transitions below 1 millisecond the level of overshoot here though is very high with an average error of 38 percent and with 55% of transitions exhibiting serious inverse ghosting despite
hitting 1 milliseconds or thereabouts this mode is unusable due to the bright trails it produces in practice so now we know that the fast mode is the best to extract maximum performance at the highest refresh rate allowed but which mode is the best to use throughout the Refresh range after all this is an adaptive sync monitor so refresh rates will fluctuate in games and could sit in different ranges depending on what you're playing having consistent good performance across
the refresh rate range is important to account for this flicking through the fast mode shows that overshoot begins to become apparent at around one hundred and forty four Hertz it's not terrible at this stage or anything but when delivering a three point seven eight millisecond grader gravure egde at this refresh a bit of overshoot creeps in the monitor still performs well at 120 Hertz but it's at 100 Hertz where we start to see noticeable inverse ghosting performance remains fairly consistent in the fast mode just below a formula ii response time average but 120
Hertz is around the usable limit for this mode below that at 85 Hertz 60 Hertz for example inverse ghosting is noticeable so I'd no longer recommend this mode for lower refresh rates however the normal mode performs really well across the entire refresh range even at 240 Hertz we're still getting a four point four millisecond grata great average which is just 17% slower than the fast mode but with the normal mode overshoot only becomes noticeable at
around 85 Hertz not 144 Hertz and even at 60 Hertz inverse ghosting isn't much of an issue meanwhile response time is fall between 4 and 4.5 milliseconds for the most part which is great for an IPS display this leads me to make two main recommendations for gaming with the 27 G and 750 if you'll be playing mostly high refresh rates above 144 Hertz in competitive shooters and that sort of thing I'd use the fast overdrive mode if you want a game at lower refresh rates or want a single mode that handles the entire adaptive sync range the best I'd stick to normal
how does the 27 GN 750 stack up to other 1080p and high refresh panels looking at peak performance so best overdrive mode for the highest refresh rate LG's new fast IPS offering holds up well it's faster than a 10 monitor like the pic 0px 5 and also manages to slightly outperform the 27 gl 850 however it doesn't quite deliver the same performance as the current generation of 0.5 millisecond class TN panels like you get in gigabytes or as KD 25 F here the KD 2 5 F is about 20% faster with the same excellent overshoot handling one of the bigger
battles is between the 27 G and 750 and the MSI ma g 251 rx the two 240 Hertz IPS monitors that I've tested one with an LG to a 7-inch panel and the other with a 24 inch uh from AO Optronics with this peak performance chart there's no clear winner here the MSI monitor is 18% faster but comes with higher levels of inverse ghosting looking at these two monitors across the refresh rate range and what's interesting to me is to find that LG's IPS panel is only
slightly faster than a you Optronics equivalent when looking at the normal mode with the LG monitor versus fast with the msi monitor in those middle refresh rates the 27 G and 750 only ends up 5% faster with slightly better overshoot handling it is however superior at higher and lower refresh rates so the 27 g and 750 is somewhat faster when comparing these two modes LG does have a slight advantage in that it's quicker overdrive mode in this case fast is better than
MSI's mode called faster msi does hit 3.2 ish milliseconds at 240 Hertz using this mode as we saw previously but it's totally unusable at 144 Hertz LG's equivalent is a bit slow at 240 Hertz but easily usable down to 120 Hertz in my opinion this makes the LG option better for high refresh rate gaming while making use of adaptive 6 so overall a Optronics does offer a good IPS panel here for 240 Hertz however LG's technology appears to be somewhat superior back to the overall comparison charts dark level performance is a non-issue with the 27 G and 750
MSI's offering is a bit better tweaked in this region but there's no dark level smearing here we also see great response time compliance for the maximum refresh rate at above 90% so don't be concerned about IPS not being good enough for 240 Hertz this latest generation is definitely good enough average error rates are kept nicely in check even using the fast mode 240 Hertz and like I talked about earlier this is one area where the MSI ma g25 one rx did suffer a bit
however MSI's monitor is faster at 60 Hertz although you'd think 60 Hertz would not be used very often on such a high refresh display input latency is a non-issue with the 2017 750 with the processing delay below zero point five milliseconds and total lag in the chain around the 6 millisecond mark this is a very responsive display that feels quick to use in all regards it's just got one of those great combinations of low input lag high refresh rate and good response times
power consumption is averaged nothing interesting to highlight here either way this is just your standard 27-inch display in terms of energy efficiency one major feature that LG does not provide with the 2070 and 750 is any form of backlight strobing for blur reduction so it's similar in this regard to the 27 GLA 50 MSI's ma g2 51 Rx and other options on the market like the sous v2 2 7 9qm do include back light strobing so for those that want this feature LG's option may not be the best I'm not sure why this is the case seems like a missed opportunity
from LG let's move into color performance now and there's nothing overly special going on here given this is an sRGB only display with no wide gamut support and despite being advertised as HDR 10 capable it's not really HDR either so don't expect any true HDR functionality with that set and 99% srgb IPS display can still look fantastic so let's see what we're working with here this is how the 27 G and 750 performs in terms of defaults out-of-the-box performance do note here that for this review and all of is moving forward we asked which
into a new Delta a formula Delta a ITP instead of Delta e mm because dei TP is the new industry standard will show de mm results here as well so you can compare to other reviews but de ITP is a more sensitive and in some ways better metric so these new Delta e figures tend to be larger the formula is specifically designed to better handle modern displays like those with wide color gamut but the basics remain the same a 1 Delta II difference is meant to be perceptible by the human eye and anything below a Delta a of 2 to 3 is generally considered
accurate my unit did have a slight pink tone out of the box but nothing crazy the CCT average curve is reasonably good but there are some issues with a low gamma as you can see in the gamma curve this leads to high Delta II performance in those upper mid-tones so it's not a particularly accurate display out of the box for greyscale with an incorrect white point these errors continue into our color tests like saturation a delta T of 9.35 is quite high using the new
ITP metric but even under the old formula we're still looking at performance that isn't fully accurate we end up with an average performance for a gaming display nothing much new in the colorchecker tests either these are average results there are two main issues with performance and we can correct one of them in the OSD and that's the white point with some tweaks that you can see here however the gamma curve problems we saw earlier can't be fixed as easily which is why when we look at grayscale performance we still end up with the delta e
above 3.0 not a terrible result and it's more accurate than it was before but it's not perfect similar story throughout the color tests improved performance but not by enough to make this an accurate display however it is possible to achieve a decent level of accuracy through a full calibration which we performed using display Cal the gamma curve is mostly resolved now leading to a delta a of 2.05 which is very solid only let down by dark performance in terms of saturation we end up with a sub 2 ponyo Delta II and in color checker around a 2.27 Delta II
average which is a great result for a gaming monitor like a lot of IPS displays the twenty-seventh GN 750 responds well to calibration and you can end up with a really nice-looking monitor peak brightness is average at around 350 nits after calibration which is fine for most viewing condition as for contrast well this is one area that LG's one millisecond class IPS panels have struggled with the 27 GLA 50s have particularly poor results the 27 GN 750 isn't quite as
bad as the 27 gl 850 but with the contrast ratio below 900 to one black levels and contrast are still a weakness for this type of panel in particular you can see a Optronics equivalent near the top of the charts in the mig-25 1rx which produces a 40% higher contrast ratio more in line with what I'd normally expect from a modern IPS viewing angles very solid though so if you're tossing up between this and a 240 Hertz TN panel generally you can expect similar contrast
ratios but better viewing angles with the LG IPS option uniformity was also outstanding with my review model well above average although IPS monitors do tend to be pretty strong in this area all up I think that LG 27g and 750 is a pretty good monitor while I have my reservations around 1080p monitors at 27 inches in size specifically if that's what you're after LG is treating you to excellent performance combined with generally solid colors I'm very happy current IPS technology allows for such a combination of super high refresh rates and a great viewing
experience a few years ago you just wouldn't get a good experience out of a 240 Hertz IPS display but now it's finally a reality the 27 G and 750 provides performance just one step behind the best teams on the market right now easily delivering 4 millisecond response times on average with this particular model being capable of those speeds across the entire refresh range you can even push it faster than that at the top end which gives a clear and responsive 240
Hertz experience given that the 27 G and 750 also packs in a decent color experience especially when calibrated along with fantastic viewing angles in uniformity I'd much rather buy this sort of 240 Hertz display then a 10 equivalent even if the TN ends up 20% faster personally I think that small speed trade-off is worth it when you gain a lot in the color department especially when current pricing doesn't make the IPS version more expensive there were some interesting findings to come out of this testing in particular one is that while the LG one-millisecond class
IPS panel is faster than a similar offering I tested from a Optronics it's not that much faster so in practice you'll end up with a pretty similar experience whether you go with the 27 G and 750 or a high quality a Optronics alternative like the msi m AG 251 r x LG doesn't have as much of a lead in this 1080p 240 hertz market as they do in the 1440p market with their flagship panel and while performance is undoubtedly very strong here giving us the best response times has led us to a few trade-offs once again we have unimpressive contrast ratio so the 2017 750 isn't
great for those that game in dark rooms LG has also neglected to offer backlight strobing both of these concerns make an alternative with the AU Optronics panel potentially a better choice given the 27 G and 750 is priced which is quite competitive with other models with similar specs it's hard to definitively say whether you should buy this or buy something else it really comes down to what you want what you're after in a monitor what you're going to do with it if you want the best performance get the 27 G and 750 if you want backlight strobing or
you need better contrast or if you aren't a fan of the size then there's a few other decent options available I'd personally lean towards the msi ma g2 v 1r X because it's a bit cheaper and has backlight strobing but that recommendation might not be right for everyone and that's it for this review of the LG 27 GN 750 hope you all learn what you needed to learn about this monitor and you can now make some good decisions about buying some 240 Hertz 1080p displays
actually really like this latest generation of IPS options it's really nice that we're getting this IPS technology available to push up to those really high refresh rates actually this means that we'll get those 1440p 240 Hertz monitors soon which I'm expecting to also be quite compelling for those that want a nice high-end option as always you can support us directly on patreon if you are interested in things like our display profiles the ICC profile that we make for this monitor is
