Yep that is exactly why as Intel have the cartel monopoly on PlayReady 3.0 DRM required for protected 4K Disc or media UHD playback it only allows playback if the IGP is present & it also requires a recent Intel SGX capable CPU to be present. I bought an X1X instead as fed up with these stupid artificial DRM restrictions. I got a UHD player as well as capable 4K gaming device for under £400!!Maybe that's why it never worked right on my X99 system? No IGP
For game HDR to work on PC you need a HDMI1.4 or newer GPU, Monitor, Video Cable & IGP present. No need for the Intel SGX CPU if PC HDR for gaming. But this is so dumb as many PC games allow you to enabled HDR but its not actually working in game at all just washes the image out!
I still also play on my PC but I can see the writing on the wall in the immediate future X1X is the best VFM option for 4K gaming as most PC ports look inferior now due to no proper HDR implementation. X1X AF texture filtering is also superior as its newer than the PC one size fits all scheme. Cannot believe actually how little effort goes into recent PC ports vs X1X is ready to go & looks way better most of the time plus I can pick up recent games for around a tenner.
MS are onto a real winner with X1X if they can also lower the price a little as well its going to minimise PC gaming as the cost difference is vast right now!
