Question : Problem: Cannot connect DVI from the card to the monitor

Hi, mighty all

I have Shuttle SB61G barebone (XP SP3, 2 GB RAM, SATA HDD) with the latest BIOS + LG L2010P 20" 1600x1200 LCD display connected via DVI.

I used to have AGP ASUS nVidia 7600GS craphics card connected to my monitor via DVI.
Worked no probs at all. However after 1.5 years its thermal paste melted away from underneath the radiator. Which naturally caused the GPU to fry. The graphics card was declared dead.

Very well. I bought new AGP Sapphire HD2600 XT. However... Strange thing - it does not work with my LG 2010P monitor through  DVI any longer. Well, it works through DSUB (analog VGA), but the sharpness is pretty bad compared to DVI. If I plug the DVI cord (came with my monitor) there is no signal.

Both graphics card outputs are working OK - wheteher I connect DSUB cable to DSUB output, or I slap DVI-DSUB converter on DVI output.

So, I have a question. Why is this happening?

1) My monitor is too old (it is 2004 model) and its DVI is incompatible with graphics card's DVI?
2) When my old graphics card died it somehow fried DVI input of the monitor so it stopped working at all? (Is that possible?)
3) Somehow, switching from DSUB to DVI increases power consumption, so my PC's power supply cannot give enough power? (Well, I do not overclock, and I ordered more powerful power supply).

Well, I even measured the voltage of power supply by sticking a voltage meter to a spare power outlet. No difference. The PC boots - I can see by the hard drive behaviour. There is just no picture on the monitor.

I know it is silly, but I will take my PC to work - just to check it with some DVI monitor there.
But possibly someone already bumped into such problem?

PS:I know, I know my PC is old. But, hey, aren''t we all trying to be eco-friendly? Why should I throw it away if it works?

... by the way, I also have an MSI 2600XT (fanless) on another system => just for grins, I also just confirmed it works the same way.   In fact, it's been quite a few years since I've seen a dual-output card that wouldn't work with either output independently.   The only time I've seen it not work is if folks "hot plug" the monitors (I never do that) ... the cards won't auto-switch between outputs in that case (they generally do their detection at power-up).   Many years ago it was more problematic ... but even my ancient FX5500 and ATI 9600XT cards (both AGP) will work with either output independently.
