Default Dark monitor images - 11-08-2005 , 12:46 AM






I have just received a second hand Komodo (Scepter) P773 17" crt
monitor. I have adjusted the contrast, brightness and RGB color
saturations all up to 100%, but it is still has a quite dark picture. I
am running windows 98se with a ATI 3D Rage Pro video "Card" that is
integrated with the motherboard (in otherwords it is not a add on video
card). Is there anyway to brighten and/or gamma correct the screen with
either software or removing the back and turning a few pots? Like I
said, this is a second hand monitor so voiding warranty is not an
issue.

You might be able to tweak the settings via the driver: (Right-click on desktop->Settings->Advanced->Adapter, but I doubt it.

Tweaking pots inside the monitor would probably work, but you'd need to find a service manual to know which ones, and be very
careful.
Monitors have a habit of storing up an electrical charge that can kill you if you touch the wrong bit, even when they are turned
off.

All-in-all, it's probably better to get a repairman to look at it.

They used to make some transformers to step up the filament voltage when the
crts get old. Mine was getting a little dim, so I bought me a new LCD
monitor.
