Lines appearing on screen when using VGA but not when using HDMI.

Hi,

I recently made a thread on this forum talking about how my new PC setup has suddenly started creating lines on my screen

After trying a full list of things;

1. 2 different monitors
2. 2 different VGA cables
3. 3 different mice
4. 3 different keyboards
5. change power supply
6. change graphics card
7. used onboard graphics
8. switched ram sticks and removed one at a time
9. reformatted a dozen of times
10. unplugged all sound from computer
11. checked motherboard for any visual problems and couldn't see any
12. updated all drivers I could possibly think of
13. Ran Memtest for 7 passes with no errors

I've finally found out the problem and that was when I connected my graphics card using HDMI to a HDMI compatable monitor it worked fine and I had no more lines!



So it seems that using HDMI is working fine but soon as I use a VGA cable its not working and the lines are back. It only confused me more when I connected a VGA cable from another computer to the monitor it all worked fine.



As far as I can tell it's something to do with my computers VGA/HDMI settings, I've tried onboard VGA and that still didn't work so it doesn't seem to be a graphics card problem just something is stopping VGA working properly but HDMI is working.


Any help? Or I'm gonna have to go buy an expensive new monitor with HDMI compatability.

did you use the same brand and model of card when you tried another card? as some cards just have inherent problems with certain cable types. ATI are renowned for having issues with HDMI cables

Nah it was a totally different card and it still wouldn't work, the card I have in the 275 was given to me from my girlfriend who upgraded to a better card and she never had any problems with the card just seems like it is in this computer.
