"That" monitor is flickering on and off blue tint.

When I Googled it, it seems it's a video card problem. The video card on my d620 is a nVidia Quadro NVS 110M w/ 64MB of memory, apparently running at a low 69 C.

I did all the obvious stuff (reboot, reset, etc.) and it seems to be somewhat stable now.

Why is this happening and what can I do to fix it?

When you say obvious stuff, did you check to ensure the cable is plugged in completely? – JT.WK Oct 6 '10 at 0:28
Yup. I even jiggled and and replugged it. Helped temporarily. – digitxp Oct 6 '10 at 2:05
Is the cable running to the external monitor a serial connector, DVI, or HDMI? If it is one of the first 2 it could possibly be a cracked/loose pin in the connector. Test with another cable, if it is still happening with an undamaged cable than it is the output from the laptop itself. – ricbax Oct 6 '10 at 2:18
@ricbax: When you say "serial connector" I think you mean "DB15" connector (technically a "DE15"). – Dennis Williamson Oct 6 '10 at 7:25
VGA. It's the only thing my computer supports. – digitxp Oct 6 '10 at 11:27

If it is indeed S/VGA than I would first check the cable specifically Pins 1,2,3 on the DE 15 male connector.

If any are loose, bent, or broken, swap the cable and see if that fixes the issue. If not, then it is the female DE15 port on the laptop that is the problem.

I doubt it, the cable is brand new and I didn't see any problem pins when I was unplugging it. – digitxp Oct 6 '10 at 21:14
