He said he has a 1080p TV, so I assume that he uses HDMI 1.4b at best. So, a 4k@60 Hz 4:4:4 output won't be able to run on a HDMI 1.4 port that only supports 4k@ 30 Hz 4:4:4, but does 4k@ 60hz in 4:2:0. So, both devices will negotiate the connection and end up with HDMI 1.4 features in this case. And personally... 4k @4:2:0 chroma downscaled to 1080p.... What's the gain, honestly? And forcing (if that's even possible) 4k@60Hz 4:4:4 (higher bandwidth interface) to HDMI 1.4 (lower bandwidth interface) would result in a black screen. HDCP would get in the way afaik.
If he still uses HDMI 1.2 on his TV, then no. It won't run 4k at all.
An output like this may happen:
Edit: It seems I got this one wrong. It's not about outputting 4k. The output is 1080p, but the xbox downscales the 4k image internally(if you want to) down to 1080p. Compared to this, my old Bluray player was forced to output a 4k image, where the TV can't use this information. A TV itself can't downscale a 4k image down to 1080p. It would need a downscaler which supports 4k images. At least, mine couldn't. Thus it appears black.
