The LG 38GL950G-B is a great ultrawide gaming monitor that features LG's NANO IPS technology. It's the largest member of the UltraGear lineup, sporting a 38-inch 21:9 screen to deliver an immersive gaming experience. Motion handling is superb thanks to its outstanding response time and 175Hz refresh rate, but it lacks an optional black frame insertion feature. It has exceptionally low input lag, it delivers a decent HDR experience, and it comes with a Picture-in-Picture mode that can be useful for streamers and multitaskers. Unfortunately, its contrast ratio is low and there's visible backlight bleed, so it's not the best option for dark rooms. Lastly, it has native G-SYNC support, FreeSync compatibility, and there's even some RGB lighting to set the mood.
The LG 38GL950G is a very good monitor for most uses, even though it's primarily designed for gaming. Its large screen size feels incredibly immersive, and it provides plenty of screen space for productivity tasks. It has a fast response time, low input lag, and it supports variable refresh rate technology. It has an outstanding SDR color gamut for content creation and it comes with an sRGB mode that's impressively accurate. Unfortunately, it has bad ergonomics and it doesn't perform all that well in dark rooms due to its low contrast ratio.
The LG 38GL950G is a good office monitor. Its large screen size provides plenty of screen real estate to have multiple windows opened at the same time. It gets bright enough to overcome glare, it has wide viewing angles, and text looks sharp thanks to its high pixel density. Unfortunately, it has bad ergonomics, as it only allows for height and tilt adjustments. On the upside, it has low input lag and the backlight is flicker-free.
The LG 38GL950G-B is a great gaming monitor. It has a 175Hz refresh rate, outstanding response time, and exceptionally low input lag. Its large screen provides an immersive gaming experience, and its high resolution delivers a sharp image. Sadly, it has a low contrast ratio that makes blacks look grayish and there's a lot of backlight bleed, making it less ideal for gaming in the dark. It supports G-SYNC to reduce screen tearing, and it's also compatible with FreeSync.
The LG 38GL950G is a good monitor for media consumption. Its large 38-inch screen feels immersive, it has a high resolution, and it supports HDR. It lacks swivel adjustment, but you can still share content with others thanks to its wide viewing angles. It isn't the best option for dark room viewing, though, as its low contrast ratio makes blacks look gray and there's a lot of backlight bleed, which can be distracting.
The LG 38GL950G is a good monitor for content creators. The 21:9 aspect ratio is great for those who need a lot of horizontal space. Images and text look sharp, it gets very bright, and it has wide viewing angles, so you can easily share your work with colleagues. It has excellent coverage of the Adobe RGB color space and superb gradient handling. It lacks swivel adjustment, and it can't rotate to portrait mode due to its ultrawide format.
The LG 38GL950G is a decent monitor for gaming in HDR. It has low input lag, a fast response time, and it supports variable refresh rate to minimize screen tearing. It can display a wide color gamut, it has a decent HDR peak brightness, but sadly, no local dimming. Also, like most IPS panels, it has a low contrast ratio and mediocre black uniformity, so it isn't the best option for dark room gaming.
From the front, the 38GL950G is a simple-looking monitor and looks almost identical to other ultrawide monitors from LG's UltraGear Gaming monitor lineup, such as the LG 34GN850-B. It has very thin bezels on three sides and a thicker bottom bezel. The screen has a mild curve, which helps with immersion as well as visibility. The V-shaped stand is wide but the feet are thin. There are some red accents and the circular ring on the back of the monitor lights up. The RGB lighting can be customized using either the on-screen menu or LG's UltraGear Control Center software.
The stand supports the monitor well and there's almost no wobble. The cylinder that attaches to the screen is metal, but the feet are plastic.
The 38GL950G has bad ergonomics. It can't rotate to portrait mode due to its ultrawide format. There's no swivel adjustment and the tilt range is pretty narrow. If you want an ultrawide monitor with swivel range, then check out the Dell Alienware AW3821DW.
The back of the monitor is plain except for the circular ring that lights up. Unfortunately, there's no cable management at all.
The top and side bezels are very thin but the bottom bezel is a little bit thicker.
The monitor is very thick due to its curvature and requires a deep desk when using it with the stand.
The 38GL950G's build quality is good. It's mostly plastic except for the stand's trunk, which is metal. It feels very sturdy and there's almost no wobble at all.
Like most IPS monitors, the 38GL950G-B has a sub-par contrast ratio. This makes blacks look more like gray, especially when viewed in a dark room.
The 38GL950G doesn't have a local dimming feature. The video above is provided for reference only.
Impressive SDR peak brightness. It's extremely consistent across different content, and it's more than enough to fight glare in the brightest lighting conditions.
Update 09/24/2020: We've retested the HDR peak brightness using the latest firmware (version 1.20). We measure a slightly higher peak brightness overall, increasing between 10cd/m² to 12cd/m² in most scenes.
Decent HDR peak brightness. It's again very consistent when displaying different content. It's bright enough to deliver a fairly good HDR experience in video games, but not HDR movies. If you want a similar monitor that gets brighter in HDR, look into the LG 38WN95C-W.
The 38GL950G has good horizontal viewing angles. This is important for a screen this size, as it helps to prevent the image from degrading at the sides when sitting up close. Gamma shift happens rather quickly when moving off-center, but colors remain accurate until you reach moderate angles.
Decent vertical viewing angles. The image remains accurate at the top and bottom edges unless you sit very close to the screen.
The 38GL950G-B has excellent gray uniformity. The corners are slightly darker, but this shouldn't be noticeable in normal content. There's very little dirty screen effect and uniformity is much better in dark scenes.
Mediocre black uniformity. There's visible backlight bleed along the top and bottom edges of the screen. The whole screen looks more gray than black due to the monitor's low contrast ratio.
Out of the box, the 38GL950G-B has an impressive color accuracy. The inaccuracies with most colors are difficult to notice without the aid of a colorimeter. White balance is only slightly off, and the color temperature leans on the warm side. The gamma follows the target curve reasonably well, but most scenes are too bright, and the sRGB mode doesn't allow any change to the gamma setting.
After calibration, the color accuracy is superb. There's still an issue with the color blue, which is normal for an LED monitor. The color temperature is much closer to our 6500k target, and gamma is better for the most part, except for very dark or very bright scenes.
You can download our ICC profile calibration here. This is provided for reference only and shouldn't be used, as the calibration values vary per individual unit even for the same model due to manufacturing tolerances.
The 38GL950G has an outstanding SDR color gamut. It covers the entire sRGB color space, which is used in most content, and it has excellent coverage of the Adobe RGB color space, used by most professional photo editors.
Exceptional SDR color volume. It only has trouble displaying dark colors due to its low contrast ratio.
Update 09/24/2020: We've updated the monitor to the latest firmware (version 1.20) and retested the HDR color gamut. We measure a much higher DCI P3 coverage, increasing from 63.88% to 84.4%. The Rec.2020 number hasn't changed. The P3 coverage is still lower than the advertised 98%. This is due to the way that we measure DCI P3, as we measure it by sending a Rec. 2020 signal, but limit the colors to the DCI P3 primaries. This results in a lower, but arguably more accurate measurement.
The 38GL950G-B's HDR color gamut is good. Coverage of the widely used DCI-P3 color space is great, and it has okay coverage of the wider Rec. 2020 color space.
The 38GL950G-B's HDR color volume is mediocre. It's limited both by its low contrast ratio and its HDR color gamut.
The 38GL950G doesn't exhibit any signs of temporary image retention.
Superb gradient handling. There's only some faint banding in the grays, which shouldn't be noticeable in normal content.
There's no visible color bleed on this monitor.
Decent reflection handling. Visibility should be fine in most rooms and the monitor's brightness can be increased to compensate when there's a lot of glare.
Text clarity is good. Text looks sharper overall with ClearType enabled (top photo), especially diagonal lines, but some vertical lines look thinner.
|Overdrive Setting||Response Time Chart||Response Time Tables||Motion Blur Photo|
The 38GL950G's response time when playing at its max refresh rate is outstanding, resulting in very little motion blur in fast-moving scenes. The recommended overdrive setting is 'Normal', which provides the best performance with no overshoot at all. The 'Fast' and 'Faster' settings cause a lot of overshoot, leading to visible inverse ghosting.
The response time was measured in chroma 4:2:2 since the monitor can't display a full RGB color profile at a 175Hz refresh rate due to bandwidth limitations. The response time at 160Hz, which is the highest refresh rate we can get while keeping a full RGB color profile, is nearly identical or within margin of error.
|Overdrive Setting||Response Time Chart||Response Time Tables||Motion Blur Photo|
The response time at 60Hz is outstanding, and nearly identical to the response time at max refresh rate. The best overdrive setting is also 'Normal'.
The backlight is flicker-free, which can be helpful in reducing eye strain.
The 38GL950G-B doesn't have an optional black frame insertion feature.
The 38GL950G has a 144Hz native refresh rate that can be overclocked up to 175Hz; however, this can only be achieved over a DisplayPort connection, as the refresh rate over an HDMI connection is limited to 85Hz. G-SYNC is supported natively, and it's compatible with VESA Adaptive-Sync, HDMI Forum's VRR, and FreeSync.
The 38GL950G has an exceptionally low input lag, and it's only slightly higher with VRR enabled. The input lag at max refresh rate is measured in chroma 4:2:2 mode, as the refresh rate is limited to 160Hz when using an RGB color profile. The input lag at 160Hz with RGB is 4ms, and 5.5ms with VRR enabled.
Due to bandwidth limitations, we can only measure the input lag with HDR at 60Hz over an HDMI connection. The input lag at 60Hz with 12-bit HDR is 12.2ms. 10-bit HDR isn't available over HDMI and we currently lack the necessary tools to test the input lag with HDR over a DisplayPort connection.
