On the other hand, the Dell is an office monitor with two more USB 3.0 ports compared to the LG, it has a USB-C input, and it has much better ergonomics that make it easier to place in an ideal position.
The ergonomics are good. It's easy to position for yourself, but without swivel adjustment, it's hard to turn the screen to show someone next to you. While you can rotate it into portrait orientation, you can only do so in one direction, so the inputs will always be on top. The back of the monitor is plain, with a large circular red ring. There's no RGB bias lighting, and the notch in the stand for cable management isn't very useful.
If you prefer a similar budget-friendly gaming monitor with better ergonomics, look into the ASUS ROG Strix XG27ACS.
The chevron-shaped stand has a wide footprint but only takes up a little space overall. The stand is okay, though it only partially prevents the display from wobbling.
This monitor doesn't have a local dimming feature. We still film these videos on the monitor so that you can compare the backlight performance with a monitor that has local dimming.
The SDR brightness is great, but it's not quite as bright as the Gigabyte M27Q X. There's no noticeable variation in brightness with different content, and it overcomes glare in a bright room.
These measurements were taken after calibration in the 'Gamer 1' Game Mode, with the backlight at max.
The peak brightness is decent in HDR. While it's bright enough for most games, highlights won't pop in brighter scenes. It struggles with EOTF tracking, as dark scenes are overbrightened. However, it does have a sharp roll-off, and highlights display accurately up to its maximum brightness level.
These measurements are taken in the 'Gamer 1' Game Mode, with the backlight at max and HDR enabled.
The horizontal viewing angle is great. It works well for sharing your screen with someone sitting next to you, as they'll see a consistent image from the sides.
The vertical viewing angle is mediocre. The image looks somewhat washed out if you're standing up and looking down at the monitor.
The pre-calibration color accuracy is excellent in the sRGB mode. While there are some issues with the white balance, especially in brighter shades, most colors are fairly accurate. Gamma is below the sRGB target curve, and all scenes are brighter than they should be. The color temperature is a bit warm, giving everything a red tint.
The 'sRGB' Game Mode locks out a few settings, like Black Level, Variable Backlight, and Sharpness. You can adjust the locked settings in an alternative picture mode that's less accurate, as you can see here in 'Gamer 1'.
After calibration, the LG 27GP850-B has exceptional accuracy. There are no noticeable issues with the white balance or color accuracy. Gamma is close to the target curve, but both very dark and very bright scenes are too bright. The color temperature is almost perfect.
The monitor's SDR color gamut is superb. It can display the entire sRGB color space used by most desktop and web content. Coverage of the wider Adobe RGB color space used mainly for professional content creation is great, but it can't display the full range of greens, and it oversaturates reds.
The monitor has an excellent HDR color gamut. It can display nearly the entire DCI-P3 color space used by most current HDR content but falls short of the red and green primaries.
The monitor has a decent HDR color volume. It can't display very dark shades and colors very well, with darker colors appearing gray or very undersaturated.
The refresh rate is very high and includes a built-in factory overclock to 180Hz.

The LG 27GP850-B has great motion handling with VRR enabled. The 'Normal' Response Time setting is extremely consistent, as the CAD is the same throughout the VRR range, but 'Fast' is the better choice if your game maintains consistently high frame rates. The 'Faster' setting has such a high CAD that it passes the limit of the chart, as you can see here.
The refresh rate compliance is very good. It's best at lower frame rates, but like most LCD monitors, its response time isn't fast enough to keep up with its max refresh rate. The 'Off', 'Normal', and 'Fast' overdrive settings perform similarly, but 'Normal' is consistently the best.
The CAD at the max refresh rate of 180Hz is great. Motion looks sharp, and the 'Fast' overdrive setting doesn't have any noticeable inverse ghosting. It has the fastest total response time, and a lot less overshoot than 'Faster'.
The CAD at 120Hz is great. While the 'Fast' overdrive setting has the lowest CAD, it still has some inverse ghosting, more so than at its max refresh rate. If that bothers you, the 'Normal' setting performs similarly and doesn't have inverse ghosting.
The CAD at 60Hz is great. Unlike at higher refresh rates, the recommended overdrive setting is 'Normal' because 'Fast' has too much overshoot causing inverse ghosting.

The LG 27GP850-B has an optional backlight strobing feature, also known as black frame insertion (BFI), that can reduce the appearance of persistence blur. It works within a limited range and unfortunately, it doesn't work if the optional overclock feature or VRR are enabled. While it reduces persistence blur, it also causes image duplication.
This monitor has extremely low input lag for a responsive feel while gaming.
This monitor only has two USB 3.0 ports. However, if you want a more office-friendly monitor with a USB-C port, check out the Dell P3223DE.
The monitor works well with macOS. HDR and VRR both function effectively while gaming. However, there's some minor flickering with a variable refresh rate when switching from 48Hz to a higher framerate. Additionally, macOS detects this as a 31.5-inch display, but this doesn't impact performance. If you're using a MacBook, windows sometimes don't return to their original position if you close the lid.
This monitor has a few additional features available, most of them gaming-oriented. Some of them include:
