Getting More Brightness/Contrast ?

Im using an HP 90 (D2842) 19" monitor and find all movies and pictures to be too dark to view. I have the brightness/contrast setting set up to the max and the monitor's COLOR setting on RGB (set to max). Is there a way to get this monitor to display brighter? My brother's monitor from Optiquest displays just fine whereas the HP is at least half as bright. The HP monitor is working fine, it just seems HP has this unit engineered for such a low brightness level. Perhaps shaving the brightness/contrast dial-knobs so that they can turn beyond their limits could help? Thanks.

Had to move from one location to another. Soyo screen stays blue and we are unable to get a clear white screen with the blue background. Tried color changes but no luck.

If still under warranty or if you have no electronic repair experience you should take the screen back to the shop or to a repair person. screens are very hazardous to service. Even when plugged out, they can store very high voltages. Possibilities: weak CRT, low filament voltage/bad connection/bad component. possible fixes: connecting a resistor in parallel with the one in the circuit from the screen (G2) pin on the CRT, adjustment of the screen voltage potentiometer internally on the LOPT or board. If this doesn't make much sense I would suggest you take it to a service shop. Good luck

Go to "Start" , "All Programs" , find "DivX" , go to "DivX Codec" , go to "Decoder Configuration Utility" , set the brightness and contrast from there
This worked for my movies using Vista.

Dear User...

You can adjust the brightness and contrast of your monitor to improve the readability of text and to make digital pictures appear more like they'll look when printed.

To improve the results when adjusting the brightness and contrast settings for your display, use Display Color Calibration. (Display Color Calibration helps you adjust these color settings and others.) For more information about calibrating your display color in Windows, see Calibrate your display.

The way you adjust brightness and contrast varies and depends on your specific display.

Brightness and contrast buttons on the front of the monitor. Some monitors have brightness and contrast controls on the front and use the standard symbols shown in the following image.

On-screen menu. You can change the brightness and contrast settings for some displays by using an on-screen menu, and then setting the brightness and contrast in the resulting menu. Many times, you can view the on-screen menu by pressing a button-possibly labeled Menu-on the front of the monitor.

Princeton VF723 monitor is getting very dark. Brightness control is up full. Do I need a new monitor or maybe just a new driver?

i would start looking for a nice 22" LCD monitor.
Your monitor was manufactured by phillips and this symptom is very common. The crt gun gets week and has low emissions. The vid card driver has very lillte to do with the brightness control. However if your card is one of the newer nvidia or ati cards there are control ls in the software for brightness. color temp. contrast ect. Doesn't hurt to check but my guess is monitor.
Check out a LG or view-sonic for new ones.

I am using a Viewsonic VX2235WM monitor for photo editing


Its actually normal. That normally happens to some monitor models at the 6500K setting. Try a higher one.

I hope this helps.

Dark, horizontal lines after text and dark images.

This implies that your monitor had gone bad. you need to take it to a computer repair shop.

Screen is dark and contrast and brightness are up to max, can a new bulb be put into the monitor?

To replace the crt picture tube will be an expensive exercise as they are not bulbs as such but the entire screen needs to be replaced as they are a complete unit.
