Monitor quit working, with DVI-D

I have a VP201s Viewsonic LCD monitor. I have had it almost 2 years. I have always used DVI-D for it but it quit working Sunday. I was working with computer, for an hour or so, went away and when I came back there was no display. The monitor's signal check light was green indicating the monitor was receiving a signal - this light turns orange if PC is off or if screen saver puts video card into sleep mode but again it was still green but no display.

I rebooted and it worked half-way into log-on but halfway into the Windows loading screen the display went away again. I turned off computer, checked wire connections. I rebooted and this time it worked and continued working, until I turned off PC (no problems at all), for many hours. Then, the next morning, after cold-boot, it would not display at all.

If I turned the monitor off then back on, it would display for a second, then the whole screen would flicker (see parts of it strobing like) and it would make a static flicker like sound then no display *thsi woudl happen, within a split second.)

I tried another DVI-D cable and a different video card. Same thing in all cases.

I then tried a VGA cable with DVI connector adapters and it worked in DVI-A mode - no display problems at all. Also, my old CRT works fine with same PC and I got a replacement LCD monitor and it works fine, in DVI-D mode.

I assume the monitor has a tuner for the DVI-D signal and that has failed or is shorted (therefore, the flicker and static sound then no display) or something.

Opinions? Is this a comment problem with LCD monitors? Also, could going through various display resolutions (I play games and some are not played well in 1600X1200, so these games change the display resolution - does that strain the monitor?) causes this (metal fatigue, in the tuner, from the signal changing)?

Thanks for any advice, help, comments, etc.
 
Thanks. I called Viewsonic and while the DVI work-around might work, the lady said I likely have a dead port.

I'd try something like a complete powerdown of everything. (like unplug monitor, computer, everything, then plug everything back in the computer, then plug monitor in, then turn on.

I know that someone here fixed their DVI problem by doing that.
Use DVI Recover as a last alternative (last ditch effort) before you go and decide to RMA. IMHO, tech support rarely knows what the hell they're talking about. They probably just say stuff to make you happy.
