PowerDVD (previous versions) » Audio but no video on Nvidia GTX 970 4K 60HZ » Go to message
Everything is fully up-to-date (beta patch) and the GTX 970 has full H264/5 decoding plus latest nvidia drivers. Oddly I've found disabling deinterlacing then starting the video in desktop mode on the 1080p display then dragging to 4k works. Cinema does not though.



And yes I know it supports HDMI 2.0. It has to for me to be running a 4k display at 60hz... The GTX 900 series are Nvidias latest generation of cards and the only ones with HDMI 2.0.

I read about a gentleman having similar issues on a GTX 960. I am using PowerDVD on an HTPC hooked to a 4k TV. Using a GTX 970 and HDMI 2.0 at 4K and 60HZ. I have been trying to use it to pay back my DVR'd TV Show Library and I cannot get it to display video on a 4K tv. The files are 720P and 1080P H264 encoded. Disabling hardware acceleration makes no diffrence.



Oddly when I hooked up a 1080P monitor and dragged the application from the 4K TV to the 1080P monitor the video magically starts showing. Have tried cimema mode also and no luck. Got PowerDVD for the post proccessing of H264 HD video and the interface in Cinema mode. On a 4K TV other software isn't really useable due to the UI scale.



Are there any work arounds? Maybe if I rencoded the video files?
