Radeon 5770 to Samsung TV: Choppy

Hello,

I just installed a Radeon 5770 on my Win7 box so that I could connect the HDMI port to my TV and watch videos.

I'm finding the video to be a bit choppy. It's noticeable when there's a lot of movement on the screen, such as the camera moving. This doesn't occur when I play said videos on the monitor.

I'm a newbie at this stuff so I'd love to get some troubleshooting advice. CPU usage is fine. Could it be a TV issue or should I focus on the card?

Thanks!
 
My guess would be that you have a 120Hz TV and it's doing some kind of video enhancement. I think it's called Smooth Motion Plus or something like that. Disable it in your TV options.
 
I'd guess that it's something to do with the TV's post-processing functionality. I see that the B550 has a Game Mode, which typically disables all such effects. Try enabling Game Mode and see if it fixes the problem.

So, is your monitor still connected to the onboard video and the TV to the 5770? I wonder if what's happening is the media player is using the onboard GPU for gpu accelerated decoding, then piping through the PCI-e bus to display on the 5770..?

What media player are you using? Try with hardware acceleration/DXVA/DirectX Acceleration turned off, try with onboard GPU disabled, or try with all the monitors plugged into the 5770..
 
Both monitor and TV are connected to the 5770. No on-board GPU.

I've been using VLC but it looks like Media Player has the same issue.
 
Try using MPC-HC, and in Options -> Playback -> Output, make sure the "D3D Fullscreen" box is ticked. In Fullscreen section (just below Output), make sure "Fullscreen monitor" has your TV selected.
 
Have you tried running with just one display, i.e. the monitor not connected?

If this doesn't help, I suspect your TV is the culprit. If the monitor plays videos fine, it has to be the TV. I'd play around with all the settings in your TV setup and see if you can find something that fixes it.
