This is a repost from another forum that had no responses.
I have an HTPC that I built for my dedicated theater room. It uses an Intel i3 processor which has HDMI outputed to my Panasonic projector. The picture quality is very nice but I was wondering what I might expect if I installed a video card in the PC and used that instead of the onboard video. Any thoughts?

If you just use hardware acceleration then there will be little, to no difference.

The only advantage to a dedicated card for video playback is if you want to use custom pixel shaders or custom renderers such as MadVR.

I'm not challenging what you are saying, I guess I don't understand where the hardware acceleration takes place. If a video card has its own processing chip how come using that would be no different than using Intel's integrated graphics? IOW isn't hardware acceleration taking place in the video card vs the integrated graphics hardware?

well it is not all that simple. Every graphics engine and driver has its own quirks.

Since a recent update of intels drivers I was seeing some weird behavior with intel painting only half the screen when there was the slightest glitch in both OTA or Cable content. The lower half of the screen was filled with a brown/grey macroblocking.

Nvidia GPU were giving me audio clitches on certain cable channels and or certain cable commercials..


Now I am jacking with AMD Radeons and the CCC seems to have trouble maintaining it setttings, and it has a lot of those. It does not have the two issues above. But even though the drivers are better than in the past, they still are ugly and painful to work with. For the longest time I just went away from AMD altogether because you easily farkle an OS removing or reinstalling a Radeon driver set.

So it depends on what you are doing. My intel iGPUs were 2000s the 4000s might be better. I really like the simplicity and out of box picture quality of Nvidia sadly I use a Ceton and on CNN every other commecrcial would drop audio like crazy. Some channels Discovery HD did it in commercial or progam making it unwatchable. Plays fine in JRvier but Cable on JRiver is not quite ready for prime time. It is close.JRiver only does non protected content.

So it is not all the same. If you want 23.976 frame rates it is not possible with Intel, tricky with Nvidia and no problem with AMD Radeon.

There are other frame rate issues... cable tuner users who watch premium content can experience a bug that causes bad stuttering (HBO and others)..

MadVR becomes more of a concern if you move to JRiver. JRiver makes it possible to use MadVR for OTA, Cable and local content (BDs, DVDs and MKVs)

Each of the GPUs integrated or discrete has issues and depending on how you are using the PC you may or may not encounter the problem.

Just another blank signature.
