hi,
new to the forum. I have a quick question. My laptop's( toshiba satellite m45) lcd is currently broken, so I ended up using a compaq s7500 crt as an external monitor. My problem is the new monitor display is very dim. I want to make it brighter. I tried to adjust the color through the contrast/brightness button on the monitor, but nothings really changed, it is still dim. I don't know what else to do, .. I don't know if this info is important but when I went to display- setting, it had 2 copies of ati radeon , and no mention of compaq monitor? so is my laptop not recognizing the new monitor? do I need to download something? pls. help thanks
