- 27" 2560x1440 panel at 144Hz (OC scaler to 165Hz), 400cd brightness, 98% of DCI-P3 colorspace
- LG's new 1ms NanoIPS panel (same panel as used in new LG 27GL850)
- FreeSync 2 and G-Sync Compatible variable refresh rate (10-165 hz), with VRR overdrive (which the 27GL850 lacks)
- DisplayPort, HDMI, and USB-C input (with 100W power delivery on USB-C for laptops) with a USB hub.
- Pixel-duplication integer scaling as the default image scaling (with potential option for normal interpolation scaling)
- Open source firmware
This is a 1440p display, with built-in integer scaling, and you can do a perfect integer scale from 240p (6x), 480p (3x), and 720p (2x), which pretty much covers all console generations from the Atari 2600 through the XBox 360/PS3. And because it's opensource, it's likely that even if it doesn't have good OSSC compatibility out of the box, the retro gaming community could tweak the firmware to improve OSSC compatibility.
No mention of cost, but the LG 27GL850 that has the same panel is $500 USD. My gut says this will be in the $500-700 range, which is quite reasonable for a monitor with these specs.
Other things of note, the 1ms is only with overdrive cranked up to cause insane ghosting so that LG can advertise 1ms, Eve says that in the real world (with overdrive set to levels that you can't see it) 2-3ms is more typical, and IIRC 5ms is with no overdrive. There is theoretically HDR and full array local dimming support, but it's only 8 dimming zones and HDR400, which... doesn't really qualify as HDR, but you can disable the local dimming, and my understanding is that HDR10/HDR400 support costs them very little if anything.
It's still in development so there are a lot of things that they have in their list of "checking with manufacturer to see if feasible", like backlight strobing and such.
