The best way to adjust is first of all you reduce the height or make picture cinemascope. now from select button agjust vertical & horizontal geomatry now you increase the height as a whole. I think this will solve your problem. you can also refer owener manual if you have it.normally it comes with monitor. good luck/

seems like a very old monitor.
old things do that, they die , get weak, or just ugly.
this is called entropy.
if the screen or the screen line drivers are bad.
the fix is way more than a new monitor.
get viewsonic. get the VA2246M-LED OR BIGGER.
crisp perfect whites, and perfect colors... check it out.
nice price drop , reciently.....

Mitsubishi diamond pro 700 problems with screen pixles shrinking

Your monitor is overheated and has blown the tube. The only way to fix it is to throw it away and get a new one. Your not supposed to leave your monitor on all the time especially with a game just paused on the screen.

Monitor picture fades out.

I thought my problem was originally monitor related. However since I posted, the picture disappeared altogether, and my PC wouldn't even start to bootup. Fearing my mobo may have died I removed the hardware components, cleaned then re-assembled them. After all that, it turned out that my graphics card has a tendency to become slightly unseated. Once I was aware of this problem booting up resumed normally. It seems that the problem of the fading monitor picture seems to still occur, but soon after I use the machine after 'hibernation' state, and even then it doesn't always occur if I do use hibernation. I haven't used hibernation for a little while and so far the problem has not returned

Most 17 inch monitors upward have two (2) focus adjustments. They are located at the back of the Flyback Transformer (FBT) together with the screen control. They tend to "drift" as you have posted after some time of usage. In the absence of calibrating instruments, you simply have to wing it when adjusting. It might be of help if you use a squarish mirror to view the front while adjusting the controls at the rear. Of course the usual precautions apply when working with live units especially within the high voltage area.

Should you not be comfortable opening the unit, adjusting while "live", you may need to seek the services of a qualified professional.

In some extreme case, no adjustment could and would correct a problem if the CRT has already developed some form of ion burn on its mask and therefore would require replacement. At times, you may need to consider the cost of repairs (parts & service) as well as the down time which may negate justification for repairs and therefore the prospect of a new monitor might be better off.

Hope that this be of some help/idea. Pls post back how things turned out or should you need additional information.

Good luck and kind regards.

Ocassional flickering

Not sure what the problem is, but am experiencing the same symptoms every few minutes on a Mitsu Diamond Pro 91TXM, just retrieved from storage after 7 years. How's your screen holding up since April?
