I started wanting to discuss the comparison of these two as of yet unreleased screens, but realized that didn't fall cleanly into either Omegaferrari 's thread on the Asus ROG XG438Q here, or Vega or Skott 's threads on the Acer Predator CG437K P here and here respectively. Since they are both 4K (3840x2160) in resolution, 43" in size, and have refresh rates above 100hz they are begging for a head to head comparison. A summary: Asus ROG XG438Q: Resolution: 3840x2160 Size: 43" Panel Type: VA Screen Surface: AG Coating Max Refresh Rate: 120hz Adaptive Refresh Standard: FreeSync 2 HDR Refresh Range: 48hz-120hz HDR Standard: DisplayHDR 600 with Localized Dimming Image Processing: 10 bit Connections: Three HDMI 2.0 and one Displayport Other Features: Low Framerate Compensation (Automatic Interpolation at low framerates), Picture in Picture, Built in 10W speakers, Eye Comfort Certification (ensuring low blue light output and flicker-free operation, which presumably means no PWM for light dimming) Price: UNKNOWN Availability: UNKNOWN Acer Predator CG437K P: Resolution: 3840x2160 Size: 43" Panel Type: VA Screen Surface: UNKNOWN Max Refresh Rate: 144hz Adaptive Refresh Standard: AdaptiveSync Refresh Range: UNKNOWN HDR Standard: DisplayHDR 1000 with Localized Dimming Image Processing: 10 bit Connections: 3x HDMI, 1x DisplayPort and 1x USB type-C Other Features: Light Sensor for brightness, Motion Sensor Wake from sleep, Remote control Price: $1,200 (US), EUR 1,499.00 Availability: September I'll update the above as more details become available. As I see it right now, the Acer has the edge in HDR standard and max refresh rate, and hits the market in September at a fairly reasonable $1,200 USD. It lacks some details thus far regarding frame rate range, any interpolation technologies, as well as anything regarding eye comfort, and if it is shiny or has an AG coating, which the Asus all spells out. The Asus on the other hand as of yet does not have a release date or price associated with it. So much of this actually depends on seeing the screen in action, as well as getting some test results, but even so, which is your favorite thus far and why? I'm definitely buying one of these when they become available, unless a third alternative pops up by then. This is the size, resolution and feature set I've been craving for some time.
