The LG 45GR95QE-B is a 45-inch OLED monitor with a 240Hz refresh rate and a 3440x1440 resolution. It's one of the first OLED gaming monitors available in this size and competes with the Corsair XENEON Flex 45WQHD. That monitor uses the same panel from LG Display as this one, and it's bendable, but the 45GR95QE-B has an aggressive 800R fixed curved instead, which may take some time to get used to. Other than that, this model has all the features you'd expect to find in a gaming monitor, with FreeSync variable refresh rate (VRR) support, G-SYNC compatibility, and HDMI 2.1 bandwidth. It's part of the same lineup as the LG 27GR95QE-B and has the same matte screen coating. While OLEDs are prone to burn-in with constant exposure to static elements, it also has some settings to reduce that risk.
The LG 45GR95QE-B is excellent overall. It's fantastic as a gaming monitor because it has a fast 240Hz refresh rate, VRR support, a near-instant response time, and low input lag for a responsive feel. Its near-infinite contrast ratio makes it an excellent choice for dark room gaming. Because of this, it's even incredible for watching SDR or HDR movies in dark rooms and displays a wide range of colors. While it's good for office use and great for content creation, it has some limitations as the text clarity is mediocre, it's prone to burn-in, and it has an aggressive 800R curve that may take time getting used to.
The LG 45GR95QE is decent for the office, but it isn't ideal for it. It has wide viewing angles and amazing reflection handling if you want to use it in a well-lit office, but it doesn't get bright enough to fight glare. Unfortunately, due to its low pixel density, the text clarity is mediocre, as text can be hard to read at times. Its aggressive 800R curve can also take some time to get used to, and you won't see straight lines in documents. Sadly, OLEDs like this one are significantly prone to burn-in when exposed to the same static elements over time, like if you have the taskbar on the screen all day.
The LG 45GR95QE-B is fantastic for gaming. Its 240Hz refresh rate is ideal for gaming at a high frame rate, and it also has FreeSync VRR support and G-SYNC compatibility to reduce screen tearing. Gaming feels responsive thanks to its low input lag, and it has a fast response time with most signals. Its OLED panel also delivers perfect blacks, which is great for dark room gaming.
The LG UltraGear 45GR95QE is incredible for watching content. It performs well in dark rooms thanks to its near-infinite contrast ratio and perfect black uniformity. Even in bright rooms, it has amazing reflection handling, but it doesn't get bright enough to fight intense glare. Its ultrawide screen is ideal for watching ultrawide movies too, but its aggressive 800R curve may take some time to get used to.
The LG 45GR95QE is great for content creators but has some limitations. It displays a wide range of colors with fantastic accuracy in SDR. While its 45-inch screen offers a ton of space to multitask, the aggressively curved may take some time to get used to it, especially if you normally use a flat monitor. Because of this, straight lines will look curved, which can be distracting. Unfortunately, images and text aren't sharp due to the low pixel density, and OLEDs like this one are prone to burn-in with constant exposure to the same static elements over time.
The LG 45GR95QE-B is incredible for HDR. It displays perfect blacks in dark rooms thanks to its near-infinite contrast ratio, and there isn't any blooming around bright objects. It displays a wide range of colors in HDR, and most of them look vivid. Small highlights also stand out, but it doesn't get bright enough in HDR to make all highlights pop.
We tested the 45-inch LG UltraGear 45GR95QE, which is the only size available for this monitor. It was released alongside the LG 27GR95QE-B, which is also a 240Hz OLED monitor, but it has a flat 27-inch screen instead.

Our unit was manufactured in January 2023, and you can see the label here. Near the end of testing, an update was released for firmware 3.09, 1.17. We retested the SDR Brightness and HDR Brightness with this firmware, but everything else was tested with firmware 3.05, 1.13.
The LG 45GR95QE-B is a fantastic gaming monitor with both a fast 240Hz refresh rate and incredible picture quality thanks to its OLED panel. This makes it an ideal choice if you want both of those, but there are some drawbacks to it. The 3440x1440 resolution on the 45-inch screen results in low pixel density, and its aggressive 800R curve can take some time to get used to. However, both of those things are personal preferences, so if you don't mind them, this monitor is great. Still, if you find it expensive, you can get better picture quality for cheaper with a QD-OLED ultrawide monitor, like the Dell Alienware AW3423DW or the Samsung Odyssey OLED G8/G85SB S34BG85.
Also see our recommendations for the best 34-49 inch monitors, the best ultrawide gaming monitors, and the best 240Hz monitors.
The LG 45GR95QE-B and the Dell Alienware AW3423DW are both fantastic ultrawide OLED gaming monitors, but they have a few differences. The Dell delivers better overall picture quality thanks to its QD-OLED panel that displays brighter highlights. It also has a smaller 34-inch screen and better image clarity thanks to its increased pixel density. However, the LG has a higher 240Hz refresh rate, making it ideal for playing games at a high frame rate. They each have different types of VRR support, as the Dell monitor's native G-SYNC support is better for NVIDIA graphics cards, while the native FreeSync support on the LG is better if you have an AMD graphics card.
The LG 45GR95QE-B and the Samsung Odyssey OLED G8/G85SB S34BG85 are both fantastic ultrawide OLED gaming monitors, but they have a few differences. The Samsung monitor offers better overall picture quality thanks to its QD-OLED panel that delivers brighter highlights. It also has a smaller 34-inch screen and better image clarity thanks to its increased pixel density. However, the LG has a higher 240Hz refresh rate that makes it ideal for playing games at a high frame rate, and unlike the Samsung, the black levels don't raise when you have it in a bright room.
The LG 45GR95QE-B and the Samsung Odyssey Neo G9 are both large monitors with excellent gaming performance and a 240Hz refresh rate, but there are a few differences. The Samsung is a super ultrawide monitor with a 32:9 aspect ratio and has better image clarity than the LG. The Samsung uses Mini LED backlighting that gets much brighter too, but it doesn't display the same deep blacks as the OLED panel on the LG. The LG is a bit smaller with a 21:9 aspect ratio, and it also has wider viewing angles that keep the image consistent no matter where you view it from.
The LG 45GR95QE-B and the LG 27GR95QE-B are part of the same lineup and each have a 240Hz refresh rate. For picture quality, they perform nearly the same thanks to their OLED panels, and they even have the same aggressive matte screen coating to reduce reflections. The main difference comes in their sizes, as the 45GR95QE-B is bigger with a 45-inch curved screen and a 3440x1440 resolution. This offers more screen space, but the monitor has a lower pixel density and worse text clarity than the 27-inch model.
The LG 48GQ900-B and the LG 45GR95QE-B are different OLED gaming monitors. The 48GQ900-B has a higher 4k resolution and a 16:9 aspect ratio, essentially making it a small TV that delivers sharper images. It also has less overshoot with fast-moving objects, resulting in better motion handling. On the other hand, the 45GR95QE-B is an ultrawide monitor with more horizontal screen space, and its 240Hz refresh rate is also better if you want to use it for PC gaming.
The LG 45GR95QE-B and the LG 42 OLED Flex are different types of OLED displays. The 45GR95QE-B is a gaming monitor with an even higher 240Hz refresh rate than the 120Hz refresh rate on the OLED Flex, and its ultrawide screen provides a more immersive gaming experience. The 45GR95QE-B has a fixed 800R curve, but the OLED Flex has a bendable screen that you can customize from a flat screen to a 900R curve. The OLED Flex is a TV with some extra features like a built-in smart system and processing, while the 45GR95QE-B has a DisplayPort connection.
The LG 45GR95QE-B has an aggressive curve that's even more curved than some other ultrawide models like the Samsung Odyssey Neo G9. This can take some time to get used to, especially if you're looking at a webpage with straight lines. Other than that, it's a stylish monitor with some RGB lighting on the back.
This monitor isn't currently part of the Longevity Test. If you want to see it as part of our test, let us know.
The LG 45GR95QE has excellent build quality. It feels well-built with premium materials and has no obvious issues as to how it's put together. The bezels are properly attached to the screen throughout too. The stand is metal, while the rest of the monitor is solid plastic. There are some downsides, as it wobbles easily, which can be problematic if your desk moves a lot, like if you type aggressively. Also, the housing underneath the bottom bezel is very reflective and can be distracting if you have strong light sources nearby.
The ergonomics aren't bad, especially for a large ultrawide monitor like this one. The stand also has a clip to keep your wires tidy for cable management.
The V-shaped stand is fairly large and requires a deep desk to put it on. The monitor is also very heavy with the stand, so you may need someone to help you lift it. The thickness measurement is from the center of the monitor to the back of the stand, and the thickness from the side to the back is 14.0" (35.5 cm).
The thickness measurement is taken from the center of the display. From the sides, the thickness is 7.9" (20.0 cm).
The LG 45GR95QE has a remote to control the on-screen display, which is easier to use than traditional joysticks or buttons on monitors. While there aren't any other physical buttons to control the on-screen display, there's a power button underneath the center of the monitor.
OLED panels like this one don't have a backlight, so they don't require a local dimming feature. However, with a near-infinite contrast ratio, there isn't any blooming around bright objects, and it's the equivalent of a perfect local dimming feature. We still film these videos on the monitor so you can see how the screen performs and compare it with a monitor that has local dimming.
The LG 45GR95QE has disappointing SDR peak brightness, even on firmware 3.09, 1.17. It isn't much brighter than the older firmware, 3.05, 1.13. It doesn't get bright enough to fight glare, but at least it maintains its brightness consistently across different scenes. These results are from after calibration in the 'Gamer 1' Game Mode, which is the name of the picture mode setting, with the Brightness at its max and Smart Energy Saving disabled.
The SDR brightness is a bit brighter in picture modes that aren't optimized for gaming, like 'Vivid', 'Reader', 'HDR Effect', 'sRGB', 'Color Weakness', 'Calibration 1', and 'Calibration 2'. Using any of these modes also disables the DAS feature, which increases the Input Lag too. You can see the results in the 'Vivid' mode below, but the overall picture quality is also worse in 'Vivid' as the colors are off.
The HDR brightness is okay with firmware 3.09, 1.17. Some small highlights get bright and stand out against dark backgrounds, but it doesn't get bright enough to deliver a truly impactful HDR experience. Like the LG 27GR95QE-B, it has an aggressive Automatic Brightness Limiter (ABL) that makes large areas dimmer, and while you might notice it in some games, it isn't overly distracting either. Sadly, it doesn't do the best job of following the target PQ EOTF curve, as dark scenes are darker than intended, meaning it crushes blacks. However, there's a smooth roll-off at its peak brightness, meaning it preserves details well in bright scenes.
These results are in the 'Gamer 1' Game Mode with the Brightness at its max and Smart Energy Saving disabled.
The LG 45GR95QE-B has an incredible horizontal viewing angle. While it technically isn't perfect, as the image starts to fade at extremely wide angles, you won't have issues looking at the screen from different angles.
The vertical viewing angle is once again fantastic. You won't have any issues if you mount the monitor above eye level or if you're standing up and looking down at it. The top of the screen gets a bit brighter when looking down on it than in the center, but this is hard to notice.
The LG 45GR95QE has excellent gray uniformity. There aren't any visible uniformity issues, and content with large areas of the same color looks amazing. Like any OLED screen, there are thin vertical lines in near-dark scenes, but they're hard to notice unless you're looking for them.
The accuracy before calibration is fantastic. The sRGB mode limits the colors to the sRGB color space well, but some greens are still slightly oversaturated. Other than that, the white balance is fantastic, and the color temperature is close to the 6500K target. However, gamma doesn't follow the target sRGB curve at all, as all brighter scenes are too bright.
Unfortunately, the sRGB mode locks most picture settings, including Black Stabilizer and Gamma. If you want to adjust those settings, you can do that with the 'Gamer 1' Game Mode, but the colors are oversaturated, and the color temperature is much colder.
The accuracy after a full calibration is amazing, but calibrating it results in slightly more oversaturated colors. The color temperature and gamma are both nearly spot-on with their targets, and there aren't any visible inaccuracies to most colors and the white balance. Only calibrate it if you want perfect gamma and white balance; otherwise, the image still looks very accurate before calibration.
The LG 45GR95QE has a remarkable SDR color gamut. It has perfect coverage of the commonly-used sRGB color space and is also great in the Adobe RGB color space used in photo editing. However, reds and greens are still off in Adobe RGB.
The HDR color gamut in the 'Gamer 1' picture mode is fantastic. It has near-full coverage of the DCI-P3 color space used in most HDR content, and the tone mapping is almost perfect. It's also decent in the wider Rec. 2020 color space, but some colors are off. While the 'Vivid' picture mode gets brighter, tone mapping is much worse with it, so the image looks bad.
The LG 45GR95QE has amazing reflection handling. Like the LG 27GR95QE-B, it has an aggressive matte screen coating that reduces glare from strong light sources very well. However, this also results in a hazier image than monitors with a glossy coating, like the Samsung Odyssey OLED G8/G85SB S34BG85.
The LG 45GR95QE-B has mediocre text clarity, as text looks blurry at times. Due to its 45-inch screen size and 3440x1440 resolution, it has a low pixel density, which is a contributing factor to the mediocre text clarity. Another issue is that it has an RWBG subpixel layout, which not all computer programs can properly render text with. These text clarity issues are most noticeable when browsing the web or reading documents.
Unfortunately, enabling Windows ClearType (top photo) introduces color fringing, and this is because ClearType isn't designed for RWBG subpixel layouts. The photos above are with Windows 10, and you can see what it looks like in Windows 11 with ClearType on, and with ClearType off.
All four of the monitor's subpixels are never all on at the same time, and in the photo above, you can see the white subpixel. You can also see some examples of more pixel combinations below:
Thanks to its DisplayPort 1.4 and HDMI 2.1 bandwidth, you can reach its max refresh rate with any signal over DisplayPort or HDMI. Unlike the LG 27GR95QE-B, it doesn't have the same issue of displaying a 4k signal when sending a fixed 120Hz signal.
The variable refresh rate support works without any problems over DisplayPort and HDMI. It also supports Low Framerate Compensation (LFC) for VRR to continue working even when the frame rate of your game is low.
|Overdrive Setting||Response Time Chart||Response Time Tables||Motion Blur Photo|
The response time at its max refresh rate of 240Hz is incredible. While there's a bit of overshoot in dark transitions, motion still looks exceptionally smooth. There isn't any feature to adjust the pixel overdrive, though.
|Overdrive Setting||Response Time Chart||Response Time Tables||Motion Blur Photo|
The LG 45GR95QE has a very good response time at 60Hz. While the total response time is quick with most transitions, there's noticeable overshoot that causes inverse ghosting, which can get distracting with darker scenes.
The LG UltraGear 45GR95QE doesn't have an optional black frame insertion feature.
The LG 45GR95QE technically isn't flicker-free because there's a slight dip in brightness that corresponds to the 240Hz refresh rate. However, it isn't the same as pulse-width modulation because it isn't a full screen on and off, and you won't notice this flicker.
The LG 45GR95QE has low input lag with most picture modes for a responsive gaming experience. It remains low whether you have VRR on or off, or whether you're using a DisplayPort or HDMI connection. Unfortunately, the input lag increases in picture modes that aren't optimized for gaming and disable the DAS feature. These modes are 'Vivid', 'Reader', 'HDR Effect', 'sRGB', 'Color Weakness', 'Calibration 1', and 'Calibration 2'. You can see the input lag in 'Vivid' below:
This monitor's large size and 3440x1440 resolution result in low pixel density, but if you prefer a large display with a 4k resolution, then check out the LG 42 OLED Flex.
There aren't any compatibility issues with the PS5, but because it's an ultrawide monitor and the PS5 doesn't support ultrawide gaming, you'll see black bars on the sides. For 4k @ 120Hz to show up as compatible on the Video Output Information page, you may need to first go into a game with VRR enabled for 4k @ 120Hz to work properly. Although it isn't a 4k monitor, it downscales 4k signals, which results in a sharper image than a native 1440p signal.
The 3.5mm audio output serves as a combo jack with both audio out and mic in, but you need to have the USB-B cable connected to your computer to make full use of it. It also supports DTS and DTS:X audio passthrough for headphones that support it. Unlike many monitors, it has an Optical Audio output to connect to soundbars or speakers with this connection, but it doesn't support DTS/DTS:X audio passthrough.
You need to connect the USB-B to USB-A cable to your computer for the USB ports to work.
The LG 45GR95QE works well with macOS, but there are some limitations. You can't use VRR and HDR at the same time with a 240Hz signal, and you'll need to drop the signal to 144Hz if you want both to work at the same time. VRR works without issue, but there's a thin gray line on top of the screen with some games, and disabling VRR removes it. Unfortunately, HDR looks washed out, which is a limitation of macOS with some monitors. If you're using a MacBook, windows return to their original position after waking the laptop up from sleep, but not after you reopen the lid.
The text clarity seems to be a bit better in macOS than Windows, but the difference is minor. You can see what the text clarity looks like with font size 11 and with font size 13.
The LG 45GR95QE has a few extra additional features, including:
Like most OLED displays, there are also a few settings to help reduce the risk of burn-in:
Burn-in can occur with constant exposure to the same static elements over time, so the best ways to reduce the risk of burn-in is by watching varied content, hiding the taskbar, using a black background, and taking advantage of these features in the OLED Care settings. Unfortunately, LG's warranty doesn't cover burn-in. You can learn about our current longevity and burn-in test here.
