| From: Michael Hill via talk <talk@gtalug.org> | So I shouldn't be surprised that I get 3840x2160@30Hz on the newer | monitor at work | <http://www.dell.com/ed/business/p/dell-p2815q-monitor/pd> | | 1 DisplayPort | 1 Mini DisplayPort | 1 HDMI (MHL) | 1 DisplayPort out (MST) | | with the HDMI cable and mini DisplayPort adapter.
I don't completely understand why 3840x2160@30Hz works on pre 1.4 HDMI. But it does, at least in some cases. That's what I use on my desktop. You should get a DP to DP cable for work and then you should have 3840x2160@60Hz. Of course I cannot be sure since I haven't tried any of this. I cannot do that on my desktop because my monitor is really an early UltraHD TV and only has HDMI 1.3 (?) connectors. It cannot be driven 3840x2160@60Hz. I wish it could, but the experience isn't as bad as I would have guessed. There are other subtle things that more bandwidth should allow. My monitor does 4:2:2 chroma subsampling and your monitor doesn't (at least when using DisplayPort). Again, the results are usually not a problem for me, but not having subsampling is better. The next improvement will be HDR, requiring more bits of colour per pixel. Neither your systems nor mine support that. --- Talk Mailing List talk@gtalug.org https://gtalug.org/mailman/listinfo/talk
