Need some help/advice.
I have a media PC tuning my cable TV through a cablecard and Windows Media Center, thus requiring I stay with Windows 7.
Media PC specs: i3-2100, H61M-P23 mobo, 4G DDR3 RAM, Radeon HD5450 GPU. Resolution 1080p/60
The media PC has served me well for 8 years. I do NOT game on the machine, it is strictly for media playback through WMC, Youtube, and Kodi.
A few months ago, I upgraded my TV to 4k and the HD5450 does not have HDMI 2.0 to allow the desktop to run at 4k/60.
Cards that are small enough to fit and don't require an extra power connection that do 4k are fewer and further between, but I settled on a GTX1050ti.
Media PC specs (upgrade 1): i3-2100, H61M-P23, mobo 4G DDR3 RAM, GTX1050ti. Resolution 4k/60
This allowed 4k playback BUT... I was noticing stutter...a good bit of it. This was especially true when watching Youtube videos (the videos needed not be 4k videos) Even 1080i playback of my cable channels from Windows Media Center were a bit choppy. So i thought perhaps the venerable i3-2100 was just too slow for 4k playback, even if the source material was not 4k.
So I bit the bullet and upgraded to a new mobo and CPU.
Latest Media PC: Ryzen 1600, Gigabyte B450M DS3, 8G DDR4 RAM. GTX1050ti., Resolution 4k/60,
Loading Windows 7 on a Ryzen is a lot of fun, but a slipstream USB install media later and it is back up and running. However the video is tearing terribly. Not gaming mind you...watching video on Youtube, watching live video from the cablecard, even scrolling of websites, the screen tears. I've done a from scratch install twice now, so its not the initial messing around I did to make Windows 7 load. I went to the Nvidia control panel and turned on Vsync which did not help.
1. Any ideas what could be causing such screen tearing? Any fixes?
2. Absent that, should the upgrade 1 level been able to handle playing video in 4k without stuttering?
