The LG 32UD99 is a very good IPS monitor with wide viewing angles, excellent low input lag, and a fast response time. It supports FreeSync but has very few additional gaming features, and some gamers will be disappointed by the limited 60 Hz refresh rate. It supports HDR, but its effectiveness is limited by the lack of a wide color gamut and mediocre peak brightness.
The LG 32UD99-W has a decent design. It has decent ergonomics, but can't swivel, and has a limited tilt range. The monitor wobbles a lot, even while you are just typing. The stand is wide and prevents large objects from being placed in front of the monitor. There is a large external power adapter for the monitor, and it has a short cable that could cause some placement issues.
The stand is large, and the curved shape prevents you from placing larger objects directly in front of the monitor. The monitor wobbles significantly, even typing on a nearby keyboard causes the screen to shake noticeably. It is slightly better than the LG 32UL950.
Decent ergonomics. The stand allows you to adjust the height of the monitor, and it can tilt a bit. The monitor can also be adjusted from a portrait to landscape orientation. The stand doesn't swivel.
The back is a uniform glossy white finish. There is a small loop for cable management, but it isn't very effective at keeping a clean desk.
The LG 32UD99-W delivers good picture quality. It has a decent contrast ratio and decent black uniformity, better than most IPS monitors we have reviewed so far. It has very good SDR peak brightness, and good reflection handling, so it performs well in a bright office. The monitor has decent horizontal viewing angles, good for sharing work with nearby coworkers. Colors look great, with the excellent color gamut and excellent color volume in SDR, but, unfortunately, it doesn't completely cover the Adobe RGB color space and it doesn't have a wide color gamut for HDR.
Very good SDR brightness. The LG 32UD99 maintains consistent brightness across all scenes. This is almost the same as the LG 27UK650.
Mediocre HDR brightness. Large bright scenes are able to get much brighter for very brief periods of time, but the LG 32UD99-W can't maintain it for more than a few seconds. Small highlights in some scenes don't stand out.
Decent horizontal viewing angles. Black levels stay nearly constant at an angle. As you move farther off-axis the brightness decreases gradually and colors become more saturated. Up until a fairly wide angle, the screen remains accurate.
Great gray uniformity. There is almost no discernible dirty screen effect in the center, which is great for browsing the web or playing sports games. The edges of the screen are a bit darker than the rest of the screen, but this shouldn't bother most people.
Decent accuracy out of the box. The 'Photo' Picture Mode provided the most accurate results. White balance and color dE are high, to the point most enthusiasts would notice it but not the average user. Gamma doesn't follow the sRGB target, and most scenes appear brighter than they should. The color temperature is a bit cool, but not enough to bother most people.
Excellent accuracy after calibration. We used the 'Custom' Picture Mode, as it provided the best settings for our calibration. After calibrating, white and color accuracy is nearly perfect. Gamma follows the input stimulus almost perfectly, and the color temperature is nearly spot-on our target.
You can download our ICC profile calibration here. We don't recommend using this profile, as the calibration values vary per individual unit, even for the same model, due to manufacturing tolerances.
s.RGB Picture Mode: Custom (calibrated) Adobe RGB Picture Mode: Photo
Excellent SDR color gamut. Perfect coverage of the standard s.RGB color gamut. Adobe RGB coverage isn't as good, but it is better than the majority of monitors that we have reviewed so far, almost as good as the Samsung CHG90.
DCI P3 Picture Mode: HDR Standard Rec. 2020 Picture Mode: HDR Standard
Good HDR color gamut. Great coverage of the more common DCI P3 color gamut, but the wider Rec. 2020 coverage is only decent, and just shy of our 67% threshold to be considered as having a wide color gamut. Not as good as the Samsung CHG70
Update 01/17/2019: The Wide color gamut result was incorrect. The 32UD99 does have a wide color gamut.
After displaying our high contrast test image for 10 minutes, there is a partial residual image for a few minutes. In normal use this shouldn't be very noticeable.
Some retention is visible in our 2 minute image, but it is below the detection threshold. Note that the image we take is overexposed and this should not be noticeable under normal usage.
The LG 32UD99 has excellent motion handling. It has a fast response time that produces little motion blur, and a flicker-free backlight. It supports FreeSync, but the effectiveness is limited by the 60 Hz refresh rate. Unfortunately, it lacks an option to introduce flicker to further reduce motion blur.
Excellent fast response time. The best Response Time setting is 'Normal'. There is a bit of overshoot in most transitions. With the 'Fast' setting, there is slightly worse overshoot but not much improvement in response time.
Most of the blur in the photo above is due to persistence.
FreeSync is supported over HDMI and DisplayPort. Regardless of connector used, there are two ranges:
Update 01/15/2019: We retested the 32UD99 with NVIDIA's new FreeSync drivers. Under the 'Extreme' range, FreeSync performed identically to with a Radeon card. Under 'Basic', there was still excessive tearing, and FreeSync did not appear to work properly, regardless of the refresh rate.
The LG 32UD99 has excellent low input lag regardless of input resolution. It has a large 32" screen and excellent 4k resolution, great for multitasking. It supports a variety of inputs, and the USB-C port supports USB Power Delivery, great if you have a supported laptop or tablet.
Excellent low input lag, limited by the 60 Hz refresh rate. The input lag is consistent across all modes, even with a non-native resolution input.
There is a USB-C port that supports DisplayPort Alt Mode, which allows you to display the image from a compatible device on the screen and at the same time charge the connected device with only 1 cable. The maximum power delivery is 60W.
Update 01/22/2019: We incorrectly listed the 32UD99 as having two DisplayPort 1.2 connections. There is only one DisplayPort connection.
The LG 32UD99-W has a limited set of additional features. It has built-in speakers and supports HDR10. There is a USB-C port that supports DisplayPort Alt Mode and USB-C Power Delivery, great if you have a compatible laptop or tablet. There are no gaming-oriented features. The monitor features the standard LG joystick control, and it makes navigating the OSD a breeze. The OSD is the same as most LG monitors and is very easy to use.
The 32UD99-W has integrated speakers, and it supports HDR10. The included LG Screen Split 2.0 software can be used to simulate multiple virtual screens on the display or to enable picture-in-picture. There are no gaming-oriented features like a crosshair overlay or fps counter.
There are a few additional features that are typically found on most LG monitors, including:
The USB-C port supports power delivery up to 60W, and the USB 3.0 ports support quick charging.
We tested the 32" LG 32UD99-W, which is the only model available. There are other 4k monitors available from LG, some of which are listed below. Note that these are different models with different capabilities.
|Model||Size||Native Resolution||Refresh rate||Notes|
Our 32UD99-W was manufactured in July 2018.
The LG 32UD99 is a great monitor with low input lag and wide viewing angles, and one of the best 4k monitors we've reviewed, but the added expense for the limited HDR support might not be worth it. See our recommendations for the best gaming monitors, the best monitors for MacBook Pro, and the best 32 inch monitors.
