Poor monitor image on Micron Trinitron CRT
A friend gave me a monitor that he never could get a decent display
image on. It came with a Micron computer he bought about three years ago. It's a 19" flat screen Trinitron with the model number "CPD-4401 Trinitron" on the back. I've connected it to two computers, each running Windows XP Pro, and I also get a very poor image. The image has poor contrast, a greenish color cast, and no real blacks. It also has lines across the screen about an inch apart and maybe ten degrees off horizontal. I posted a photograph (not a screenshot) of the monitor image at: http://members.cox.net/kprdave/monitor.jpg The black border is added and is true black. I'm fairly familiar with the adjustments on my other monitors, and this is the best I can get, even using the color correction in my video card's software. In the Device Manager, it's listed simply as "Plug and play monitor." I can't get any info about the monitor from the Micron website as they seem not to support any hardware but memory anymore. I didn't have any luck at the Sony site either. I did find a Win. 95/98 driver and tried that, but it didn't improve the display so I rolled back the driver. Any help would be appreciated. Thank you. |

It's a re-badged Sony Trinitron. Go to Sony's website and get their .inf. Also
do a google search on CPD-4401. A friend gave me a monitor that he never could get a decent display image on. It came with a Micron computer he bought about three years ago.

What strikes me as odd is that the former owner accepted this monitor instead of having Micron replace it. Regardless, it appears to be a hardware fault within the monitor itself. With TV sets it could be related to a capacitor failure in the vertical sync circuit, though I don't know if this applies to monitors as well. I seriously doubt that anything other than repairing the monitor's internal fault can compensate for this and result in a reasonably useable monitor. You might leave it unplugged for a few days and then open it, see if there's any obvious sign of problem, but remember that this is potentially lethal high-voltage, not something you should be messing with if not already knowledgable in such things. If I had to guess, a repair shop might want $60 to fix it, though YMMV, I could be wildly off. If the monitor hadn't been used much in it's 3-year life due to the problem then it might easily be worth ($60?) to fix it. Dave |
