LG have announced their new 27GN950 display, due to be showcased at CES in January. This new 27″ screen features a Nano IPS panel with a 3840 x 2160 UltraHD resolution along with a 144Hz native refresh rate and 160Hz via an overclocking feature. A single DisplayPort 1.4 cable provides support for VESA Display Stream Compression (DSC) technology for “virtually lossless performance” when handling 4K UHD images in 10-bit colour at 144Hz. The screen also supports adaptive-sync for VRR support from both AMD and NVIDIA systems. The screen will be certified ‘G-sync Compatible’ as well for verified performance.
Display Stream Compression (DSC)
There is no need for chroma or bit depth colour compression here like the earliest 4K @ 144Hz displays, like the Asus ROG Swift PG27UQ or Acer Predator X27. Those high end models could run up to 98Hz with 10-bit colour and without any compression, but anything above that required some form of compression due to the bandwidth limitations of DP 1.4.
We have seen a couple of screens announced from Asus before which feature this DSC method instead like the Asus ROG Strix XG27UQ and the ROG Strix XG43UQ , but neither have been released yet or reviewed. It remains to be seen of course whether there are any drawbacks to using DSC or any visual loss to the quality.
Other features and specs
Interestingly and unusually the 27GN950 also offers hardware calibration to maximize the ability of LG’s IPS technology to realize precise color reproduction. That’s usually reserved for professional grade screens, not gaming line-ups.
There is also VESA DisplayHDR 600 certification on this model which should at least provide some kind of meaningful HDR experience, with edge-lit local dimming. This also offers a peak brightness of >600 cd/m2, and the screen also supports 1.07b colour depth and a 98% DCi-P3 wide colour gamut.
In other specs there is a 1ms G2G response time (take with a pinch of salt) and 450 cd/m2 typical brightness. The stand offers tilt, height and rotate adjustments (seemingly no swivel according to the press release info?). There are 1x DisplayPort 1.4 and 2x HDMI 2.0 connections offered along with 2x USB 3.0 ports.
The 27GN950 will use LG.Display’s own Nano IPS panel which according to the latest information we have is not scheduled for mass production until Q3 2020. So we wouldn’t expect to see this new display until Q4 2020 at the earliest sadly. An additional note, it does look like the new panel will be one of LG.Display’s new ‘Oxide’ designs with 4-side “real borderless” that we talked about in our recent news piece.
