This has been bugging me for a while now, windows 10, new motherboard, HDMI to 4k tv [600 nits], intel uhd on board display adapter running at 60hz, when I play a 1080p encoded video with, for example, Windows Movie and TV app, it plays fine, but when I play the same move or show in a 2160p encoded video it shows so much darker to the point of making it unwatchable. Pulled up the same show, one in 1080 the other in 2160 and took a screenshot, and am attaching it to this post. Does anyone have any idea why this is happening? The fact I can screenshot it and it looks darker in the screenshot seems to tell me it's not the fault of my TV, but I can't figure out for the life of me, what I would upgrade to allow the 2160p encoded videos to play as bright as the 1080p videos, I know I could mess with the brightness on either the display or the video app, but why should that be necessary (windows Movies and TV app does not have a adjustable brightness, but the "glamour" of the videos it plays beats any other video player out the door, by miles, if you know you know). Cheers.

Are you comparing the 1080p and 2160p video on the same screen? Are you using any enhancements such as HDR?

[–] [email protected] 1 points 1 year ago (1 children)

HDR is off (because it dims the video produced and washes it out), both the 1080p and 2160p in these examples are taken from the same machine on the same screen, and as stated if we can see the difference in brightness in a screenshot that about takes the screen being the issue out of the equation)

Ah, sorry, it wasn't clear that you were doing the same thing on the same screen. Have you tried testing it with a different media player?

Sure, I've used VLC and Windows Movies and TV as the two main players, WMT simply delivers better quality video than any other video player for Windows anywhere, it's jut the 2160p are darkened to the point of being unwatchable, it's most likely a video card processing thing, but this whole HDR thing has got me so confused and I'm a tech guy. I was on vacation and hooked my mini pc up to the HD TV that was there in the place, and the video from a 1080p file that just showed fine on my home HD TV was showing like it was on a showroom floor, crytal clear with ultra spacial definition, I looked up the TV on Amazon and it's not much different than the one I have at home. I just can't figure this HD thing out, wish I could understand it, and more importantly reproduce it at will. The experience with the mini PC with a build in UHD Intel chip (same as I should have on this new motherboard at home) producing such crisp excellent video, which of course I could not reproduce playing the same clip from the same mini pc on my home tv, has got me posting on KBIN.

Yeah, I can see how this would be frustrating. The only things I can think of are that HDR is doing this (it has been known to cause similar issues) or there's something up with your Intel chip.
