4K or HD?

Dear Wikipedians:

I have a 4K monitor and a (supposedly) 4K cable IPTV box. I have tuned the IPTV box to a 4K channel. However, when I look at the "info" section of my monitor's menu, it still says the resolution is at standard HD 1920×1090. So I am a bit confused: is the channel I'm looking at actually playing at 4K or has it been downgraded to standard HD? I have attached two screenshots here.

Any insights would be much appreciated!

There are a lot of compatibility issues. The monitor may only accept 4K on a particular port. The monitory may need a special configuration setting to allow the 4K to work, and it may do so by sacrificing something else, say frame rate. The standard that the monitor uses may not be the same as what your box is putting out. Perhaps the bandwidth to the box is not actually enough to support 4K and it down-grades. WiFi often cannot provide the bandwidth, so an actual copper Ethernet connection ma be in order. Graeme Bartlett (talk) 23:49, 10 June 2018 (UTC)[reply]
