Hi Guys....

Installed my brand new GeCUBE HD4850 1gb today.
Problem is the display looks "twitchy". the screen jumps around from left to right, almost like when you press the "auto adjust" button.
Ive checked that I have the latest graphic drivers, what can cause this? any suggestions?
 
Do you have another monitor? tried another cable? What happens when you put your old card back in?
 
if I put it on 75Hz its even worse. My min Refresh rate is 60Hz (thats what Im running now, and Ive always been running 60Hz)
 
Ill get another monitor tomorrow, and test it. I doubt its the monitor, or the cable.
It does almost seem as if ithe monitor cant find the right refresh rate.
 
Just Tries to play counter strike, then Its even worse. Could this maybe have something to do with the fact that my PSU may be to weak for the GFX card?
 
I don't think insufficient power would cause something like that...
 
it's is called dot crawl, when a poor monitor (your tv makes a poor monitor for displaying vga+ type signals) cant correctly lock onto the picture..it kinda moves one line left, fuzzes a bit, move right, blah blah.

see if you have a setting for pixel clock on your lcd tv (may also be called phase adjust...think!) and play around with it.

otherwise, download and use powerstrip, and find your lcd tv manual to get the correct timings required.
 
Ive got a advanced setting for "phase" and "clock"
Phase is currenty sitting at 12 (out of 100), and the clock at 48.
It also has an "auto adjustment" button, but after the adjustment just looks blurry again.
They dont mention anything in the manual, how to set the "phase" and "clock", can anyone give me some pointers?
