Question about Dell M992 19" CRT Monitor

Severe gradient issues / problems with darker grays

I have a Dell M992 CRT monitor and just this morning when I turned on my monitor I noticed something odd. In bitmap images (regardless of format) all my greens / grays are a darker purple color. images don't show up properly (most are in some random collection of purple tones. I checked a gradient test image to see what was up, and I noticed that the white to black gradients go from white to purple to black. I looked into it and apparently this happens to a lot of flatscreen monitors... but not always to CRT. So I'm confused. Do I have to get a replacement or is there someway to correct this with software? I might also add that video games show up fine. I played Half-Life 2 and there were no color issues. I'm pretty damn confused.

Re: Severe gradient issues / problems with darker grays

So your sure when you go into the monitor settings, and color, it is set to like 9300k or something? It probably isn't the monitor, because the video games you said display just fine.

The labor rate in the midwest where I live is $50 just to look at it. Unless you have electronic experience and test equiptment, I do not believe you wil be ableo to service it yourself.Usually cheeper just to buy another replacement one.

Dell m992 crt monitor

If it's getting no signal, make sure the monitor is set for the correct input. This would be either analog (if your cord has blue ends) or digital (if the connectors are white). Depending on wt yhat your monitor is, a button on the monitor will help you set that. If it's set for the correct input signal, then switch out a different cable to see if perchance you have a bad cable out of the box. If there is another PC or laptop setting around, plug your monitor into that to make sure it's good and maybe even plug THAT monitor into yours to make sure there is nothing wrong with your video card. Let me know what transpires. If this takes care of things, please help me out by rating it accordingly.

Out of frequency

Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!

Dell m992 screen problems

If you notice, when you see the windows start screen, its usually "big and dopey". Thats because the video drivers aren't being used yet. If it is blanking out right after you see that screen (with the scrolling bar), my guess is it's a corrupt / bad video driver.

Was any other hardware added recently?

The link below is a Digitally signed M992 monitor driver. Also try upgrading to the latest ATI software and drivers. You can also try and change the frequency refresh rate to 75mhz. It in the Control Panel under 'Display' and tab 'Monitor'. It shows a list for frequencies you can try.
