There are many various interfaces under the VESA standard, which differ in the size of the brackets, the distances between the screw holes and their number. Colours looked vivid and bright thanks to the wide gamut backlight but the colour balance and temperature felt good. Luminance uniformity of the screen was very good on our sample, with all of the screen within a 10% deviance of the centrally calibrated area which was pleasing. To be honest we’d have rather LG had stuck with a more traditional response time spec like 4 ms G2G and delivered a great performance in that range, than push unrealistic and unachievable marketing figures that don’t live up to the hype. There may be a need to switch between different overdrive settings in some cases, depending on your usually attained refresh rate output and graphics card capability.

Contrast ratio is the visual distance between the lightest and the darkest colors that may be reproduced on the display. The screen was tested at default factory settings using our new X-rite i1 Pro 2 Spectrophotometer combined with LaCie’s Blue Eye Pro software suite. Most of the OSD controls are locked at the end, although brightness is left available which is good news if you want to change that for different times of the day, or to your liking. A slight darkening of the image occurred horizontally from wider angles as you can see above as the contrast shifted slighting. In fact the image looked so good, it was not far off a native 1440p screen we felt when comparing side by side.Display have made excellent advances in the high refresh rate IPS space with their Nano IPS technology. It’s not really very noticeable in games and multimedia, but certainly more noticeable in desktop use where fonts can look blurred and show colour fringing. The on-screen reticle is the same as most monitors: great if you need it, but best avoided in online multiplayer to keep things fair.

You can also manually enable or disable local dimming – or set it to ‘auto’ which will enable local dimming whenever HDR content is detected. You’ll want to use DisplayPort to make the most of its feature set, but I liked that I could easily connect my Xbox One X and swap inputs when I wanted to put my feet up.

A good gamma and white point setup along with a wide DCI-P3 colour gamut and good contrast ratio (for an IPS panel). We separately measured the colour space using ChromaPure and thankfully confirmed that the sRGB gamut had been properly emulated, measuring 97. It offers smooth performance thanks to its 144Hz refresh rate, 1ms response time, and variable refresh rate while its IPS panel ensures accurate and vibrant colors. The most widely used panels are those with 6, 8, and 10 bits for each of the RGB components of the pixel. At each brightness level we also measure the contrast ratio produced by the screen when comparing a small white sample vs.

We carried out some further response time measurements at 160Hz which is the maximum refresh rate of the screen with the overclock feature enabled. The operating humidity shows the acceptable level of humidity, in which the display will function flawlessly. You can always set one mode up with sRGB and another with the full Native gamut if you want, or change back to the other preset modes where wide gamut is used for gaming etc. According to LG, the 27GN950 also supports the 2560×1440 120Hz mode with FreeSync Premium Pro over HDMI for the Xbox One X. I wish it had a few more gaming features, but there’s no mistaking that this monitor is an absolute winner.Alternatively, consider the Acer XB283K KV with a USB-C port and 65W PD in case you have a compatible laptop. The overdrive has been optimised here for achieving a good balance between driving faster response times, and avoiding too much overshoot creeping in at the lower refresh rates. It is providing a higher pixel density (Pixels Per Inch, PPI) to improve the degree of definition to the image.

It did perform better than the Asus ROG Strix XG270UQ (which also offered 4K resolution, 144Hz refresh rate and uses DSC to avoid colour sacrifice). was the maximum available and there was no sign of any overclocking feature in the OSD menu either to push it higher. Enabling VideoSync mode in LG’s UltraGear Control Center app allows the backlight to match what’s happening on the screen, projecting it on the wall behind.The 103 third parties who use cookies on this service do so for their purposes of displaying and measuring personalized ads, generating audience insights, and developing and improving products. Thankfully there is a way to have even better control and accuracy including with an emulated sRGB colour space, but you will need to be able to hardware calibrate the screen. We carried out our testing using a brand new NVIDIA GeForce RTX 3090 graphics card, that supports DSC. A high contrast ratio is desired, resulting in richer dark colors and more distinctive color gradation. In the “TV” section of the graphics card settings (labelled “Ultra HD, HD and SD”) we saw options only for 4K and 1080p.
