HDMI connection, GPU or Mobo?

Does anyone use PowerDVD for UHD discs and MC for Blu-ray rips to the TV via one HDMI cable from the graphics card?
Thanks

Outputting to NVidia HDMI and using Nvidi GPU are not the same thing.
I tried PowerDVD … didn't like it … so did not buy it. What PowerDVD do before playing UHD disk is:
1. check if you have required Intel CPU to run secure environment
2. check your HDMI output for HDCP compliance (NVidia HDMI does comply)
3. check that receiving device on other end of HDMI is also HDCP compliant
In theory running in secure environment prevents decryption key beeing stolen ... and HDCP compliance prevents recording directly from HDMI output ... in reality both things failed to do what they were ment to ... but it does not stop Big Studios to enforce these rules on PowerDVD (not easy for average customer to bypass those securities)
Whether PowerDVD will use NVidia GPU to do any processing (decoding or scaling or other stuff) is not known to me. But as HDMI ports of NVidia cards are HDCP compliant (need to check specific version of HDCP for UHD compliance), PowerDVD can output video to those ports.
As for playing MKV and using GPU to do it ... that entiry depend on what player you using. If you use RedOctober Standard, I believe it can only use GPU to decode videos ... if ypu use RedOctober HQ (aka MadVR), it can milk your GPU dry while upscaling videos.

I guess what this comes down to is whether onboard and discreet graphics can be used for separate applications. Ie, I put an encrypted UHD disc in and press play in PowerDVD and it plays (via intel onboard graphics) or I access an mkv file or iso or whatever file in MC, press play and it plays via the discreet graphics. Both via ONE HDMI cable.
Can that be done?
This is all based on the assumption that UHD encryption gets better and is not solved, and our personal owned media can then only be played with PowerDVD on a computer.

Yeah ... I believe it can (did not try myself) ... so both PowerDVD and MC output through one HDMI port on your NVidia

Thanks
Anyone done this and can confirm?
Cheers
