Display

I have noticed that whenever the weather gets hot my computer screen would keep flashing. I don't really know why but that is certainly not something that I'd appreciate. I have made up many causes for that but it seems none of them are correct. When it first happened last year I did not link it to the hot weather, instead I blamed the power source thinking that it might be not enough power, but it does that again when I moved which eliminated that assumption. Then I couldn't live with it anymore because it's just annoying to see the screen go black for a second or two every twenty seconds. I checked all the possible settings I get access to and found that the Catalyst control centre offers an 'alternative DVI mode' switch which seemed to work, but not every time though. Then I thought the problem might lay with the fact that the cable's not properly transferring data as it should as it was a cheap ass HDMI cable that I had, then I spent quite a bit of money and bought a proper DVI-HDMI cable instead of using the converter supplied with the graphic card (there was only two DVI sockets and an S-Video/S-PDIF outlet on the Radeon HD4850, and I used a 22" Samsung TV which only has HDMI or VGA to connect to computers), nope none of them helped.

And here I am now thinking the problem is gone, simply by switching back to good old VGA (still requires a converter) instead of HDMI connection, and the problem seems to be gone. Only thing is that after being so spoiled by the HDMI I could surely notice inferior graphics that VGA offered which I wasn't aware before. But well, having a slightly worse graphics is still way better than that annoying flashing screen.
