First off, I've had a Zalman Trimon 22" 3D monitor since last spring... and it's always worked like a charm. (Technically, I've got a dual monitor setup, the 2nd monitor being a non-3d Asus 22" with the same available resolution set as the Zalman.)
The trouble started when I took my computer over to my sister's the other day (box only), plugging it into a different primary monitor. Got home later and plugged back in my Zalman 3D, ready to fire up some S3D gaming. Unfortunately, the available resolutions are restricted now, and the requisite 1680*1050 is no longer available. No 1680*1050, no S3D.
Taking a closer look in the display settings, I noticed that my Zalman is listed as a "Generic Non-PnP Monitor", while my Asus is shown as a "Generic PnP Monitor". Unlike my Zalmanm, my Asus is currently allowing the expected resolutions, so now I'm thinking it's a driver issue. Thing is, after checking, both monitors are using the same driver! And the option to roll back the Zalman driver is greyed out (indicating it hasn't changed)...
After some head scratching, I next tried the "Allow all resolutions" option on my Zalman, which as expected, allowed 1680*1050. Thinking I was all set for S3D, I fired up Mass Effect, only to discover that the game only allows the aformentioned limited resolutions, (based on the Non-PnP).
So now I'm stumped... Hope it's something obvious that I'm missing.
In any event, any help getting me back up and running again would be much appreciated. Thanks!
