Hi,
On my XPS8500 I cannot get the DVI or HDMI ports to output a signal correctly although VGA works OK:
I've been using an LG 22" monitor with my Dell Vostro 200 with a card that had DVI output and it works fine but on the XPS8500 it gives no signal, I've uninstalled and reinstalled the latest Dell driver and removed hardware from Device manager, when I do this I find that upon reboot the GT620 outputs at the native 1650x1050 res until Win7 fully installs the driver and requires a reboot, upon reboot no signal is output. This happens on DVI and HDMI.
While in this no signal condition the VGA does not output until I remove the HDMI or DVI cable from the monitor so something is deactivating VGA at that point.
When booting up connected via DVI or HDMI cable, there is no Dell BIOS screen or the Win7 bootup screen either.... again VGA is fine.
Is the GT620 just crappy or am I missing the point!?!
