Problem - Blocky image at 1920x1080 @ 120hz
Hi,

I am running:

[list]

[*]2 x 295 GTX cards (Quad SLI)
[*]3D Vision glasses & transmitter
[*]LG 2363D 120hz monitor
[*]i7 920 on a Gigabyte X58 UD5 board with 6gb of memory
[/list]

I had been using the system fine for ages, 3d working well, it went into storage for a while when we moved house.

Just set it all up again and the 1st thing that came up were a bunch of updates inc the Nvidia driver. I did the updates (280.26) inc the stereoscopic drivers. I now have a couple of confusing options in the control panel.

If I use "HD,SD 1920x1080" @ 59hz (no other refresh rate comes up), the screen looks fine, if I select "PC 1920x1080 (native)" @ 120hz, the screen goes all blocky. I am connecting the monitor up with a DVI cable. When using the "HD,SD" setting I can play games in 3D, but they are blocky. When selecting the "PC" option, the 2d (desktop) is very block and games show a message about using an unsupported mode.

Can anyone suggest how I might get things back to normal? I just want to see the desktop clearly (at native resolution and refresh rate) and to play 3D games at the native resolution without it being blocky. Is there a known issue with the latest drivers as this never happened before.

Thanks

Likely a bad cable, or wrong cable.
Mak sure you have the Dual Link DVI cable that came with the monitor plugged in.
