Question Differences between HDMI 2.0 and HDMI 1.4 for my setup ?

[minnin90]

Getting a desk back together and using a PC and an Xbox Series S for gaming has been pretty fun but I have a question that I can't figure out for some reason.

So I got this monitor: https://viotek.com/viotek-gnv32db-3...-2560-x-1440p-g-sync-ready-freesync-with-lfc/

As it states it has 3 x HDMI ports but only one is HDMI 2.0, the others are 1.4.
To get the 144hz correctly on my PC can I still connect the PC to a 1.4 port so my Xbox gets the 2.0 port for 120hz?

I know its a simple question but I can't seem to find a good answer. Thanks all. Also welcome back to the forums, ME! It's been a while!

Not Hdmi 1.4, it doesn't support variable refresh rate either. Use Hdmi 2.0 for Xbox and Displayport for PC. Your graphics card has Displayport?

@1080p HD
V1.4 hdmi capable of maximum of 120 Hz
V2.0 up to 144Hz
V2.1 up to 240Hz

Both 1.4 and 2.0 support fixed 120Hz or 144Hz 2560 × 1440 non-HDR but 1.4 must drop to Y′CBCR 4:2:0 color subsampling

Unfortunately no, its a laptop so just HDMI.

I've never really understood 4:2:0, 4:4:4, etc.

What laptop is it? If it has usbc capable video port then you can use Displayport. That's if it has, it might not, but if it does, a usbc to DP cable would do the trick.

Search for one on Amazon, one with high sales. Usbc to Displayport.

Not every usbc port supports video, the manual for your laptop should describe if it does.

4:2:0 chroma subsampling reduces the resolution of the color components to 1/4 of normal. So for a 2560×1440 image, only the brightness component would be at 2560×1440, the two color components of the image would be reduced to 1280×720, which cuts overall bandwidth in half but with reduced image quality.

Sadly that kinda stuff goes over my head, apparently even when explained, lol. I understand 4k, 2k, 1080,etc but when it gets into how image quality is "Cut in half" not to mention upscale in video games, I'm like, what!?
