generic non pnp monitor problem

[Netheros]

Hey guys.
I have the HD 7970 vortex 2 graphics card. When I first installed it in the screen resolution panel it wouldnt recognize the monitor and it said generic non pnp monitor and the resolution couldn't go beyond 1680x1200. Anyway with some catalyst settings I was able to put it customly at 1920x1080. But it still said non pnp monitor. After that I installed my old gt 220 gpu and its drivers and it recognized my monitor.Then I reinstalled my 7970 and it still didn't recognize it.I read somewhere that if you unplug the power cord for a few minutes it's supposed to fix it. I will try that some time later but do you guys have any ideas why this is happening? And I am using a dvi to vga adapter to connect the gpu to the monitor.

who makes your monitor & what is the model number of it? with the old card, were you using that vga to dvi adapter or straight vga into the videocard?

My monitors model is LG flatron w2240 and yes with the old card I connected it straight with the VGA cable.

it is that adapter that is causing the problem. what video ports are on that monitor as my 2 acers 24" monitors have vga, dvi & hdmi wereas my 19" & 20" samsungs have vga & dvi?

The monitor has only vga input. Will i need to upgrade to a new monitor(current one is 5+years old) or is it that particular adapter?

how many pins show on the vga connector of the monitor cable? I have that vga female to dvi male adapter on my test monitor & it works as my monitor cable shows 15 pins.

can try a different adapter but take your monitor with you to see if it works or not or get a new monitor that has dvi, hbmi & maybe a display port on it.
