Screen Jerking/Twitching?

I recently bought a Sapphire 7850 with a 550W power supply, and I noticed that I get this hardly noticeable screen jerking, in an upwards movement, and I also sometimes get horizontal static faint white lines, but thats not my main concern.

8.00 GB DDR3 @ 666MHz
AMD A6-3650 CPU
Gigabyte GA-A75M-D2H mobo
ZORAN TV (1920x1080@60Hz)
AMD Radeon HD 7800 Series (7850)
977GB HD

All my graphic drivers are up to date, I did OC the clocks on the gpu, but it started before I did that, and I tried changing them back to default and still happening.
I tried going into the BIOS and disabling the onboard graphics but I couldn't find the option to.

What brand and model of PSU? Are you using HDMI to connect to the TV or something else? Have you tried testing with a real computer monitor? Are your GPU drivers up to date (12.4)?

Gpu drivers are up to date, I am using a OCZ brand power supply. I have it connected to the monitor mentioned above with a vga-dvi adapter on the GPU

Try a real computer monitor (not a TV!). TVs suck not only in terms of PPI but also display modes. Regular monitors tend to be plug and play, but TVs often need many configuration changes on the software side to get things to work perfectly. You could look into CCC's TV configuration options and tweak those.

Well he is correct. Off brand TVs are probably even more finicky then a name brand. So it may be just that, as in go buy a new monitor. Not that im saying that is the solution, recently ive been building a few custom HTPCs and using them on my Dynex 46 inch 1080p TV and there are no issues and that isnt exactly a name brand either. Hard to tell. Could be the input onthe TV, try a different input.

If you can't find a monitor to test your own GPU on, find a laptop to test your TV on, plug into the same port and if it does it on the laptop (or other desktop..) then it's the port, try a different port, still doing it? TV.
