Bad screen or GPU chip?

Hi,

Screen or Chip? (see attached).

Starts doing this on the screen after about 2 - 3 mins of firing up. Nothing in particular is causing it but it outputs to HDMI fine.

Moving/manipulating the screen does not help.

Let's see... It outputs to HDMI fine as in bypassing an HDMI cable from it to another monitor? If so, I don't think it is the chip. Unless you bypass the HDMI to another monitor, turn them both on then monitor (as a verb) both and see.

Let's wait for the experts.

If it works fine with the HDMI cable from the PC to the monitor then it's not the chip.

What other video outputs you have on the Vcard?
