Very good monitor, including PS4 Pro.
The PS4 Pro rarely reaches 60FPS even with Boost mode, the 75Hz of the monitor is more than enough.
The HDR of the PS4 Pro is not taken into account but very few monitors have HDR. At the moment this is mainly for TVs and smartphones.
The contrast of the Asus VG245H already does its job very well.
In principle, nothing stands in the way, but it should be noted that the screen "only" offers Full HD and is therefore not suitable for higher resolutions. The response time is crucial for gaming and is in a good range for this.
VG245Q is newer and has Display Port. NVIDIA cards need this for AMD FreeSync. The average response time of the VG245Q is 3 ms, which is faster than the VG245H (5 ms). Translated from https://www.gpucheck.com/compare-monitors/24-asus-vg245q-vs-24-asus-vg245h/ - Greetings
Try it this way https://discussions.apple.com/thread/6620835 unfortunately refers to an old mac os x and otherwise possibly netflix app via app store ?
The specified reaction time has nothing to do with the signal itself, but describes the time in which a pixel must change colour. Not to be confused with input lag.
