Thanks in advance!
What 4K TV/monitor do you have?
|Radeon HD 7750 and higher||GeForce GT 640 and higher||Intel HD 4000|
|4Kp24 decode||Up to driver||Yes||Yes|
|4Kp60 decode||Up to driver||?||Yes|
|4Kp24 output over HDMI||Yes||Yes||No|
4Kp60 output will be supported by the upcoming HDMI 1.5.
Yes. I am also surprised that it's only me in the world (besides Intel developers and perhaps ArcSoft people [only ArcSoft Video Decoder from the latest TMT build works]) who confirmed this.
BTW Intel HD Graphics 2500 also can decode 4Kp60 (CPU usage of i5-3550 is only 5% at perfect smooth 4Kp60 playback), but GPU usage is very high (~90%) even when outputting video in 1:1 (so 3/4 is cropped in a 1080p display). It looks like post-processing taxes this weak GPU.
