If geeks love it, we’re on it
You found the friendliest gaming & tech geeks around. Say hello!
I want to know that it is possible to adjust focus with DAS(dos based) software or is there other way to adjust focus? In my case all horizontal lines have "shade" under(about 1,5mm) the "real" line. Computer and cable are ok.
Older model this was easy to do with potentiometers...
You can do focus on the flyback, there are two adjustments. These adjusments are usually fixed in place by some white paint. They should not need readjustment under normal circumstances. Maybe instead the problem is convergence?
Adjust F2 focus VR for best vertical focus.
1) Adjust the F1 focus VR for best horizontal overall focus.
2) Repeat F1 and F2 as there is some interaction.
Basically 3 out of 5 times I switch on the monitor, the brightness is 30% more than it should be so I have to switch the monitor off 2 or 3 times before the image is displayed at the correct brightness.
Also as someone mentioned earlier about the picture flickering for 2 seconds and returning after extended usage, I also have this problem and it usually happens after the monitor has been on for over 2 hours or so.
Any help would be greatly appreciated
Not familiar with that model but in any case maybe more information is needed.
When the brightness is incorrect, is the number displayed in the on screen menu for brightness incorrect also (does it change or remain constant regardless of brightness)? Are all colors equally bright, or does the screen take on some particular hue? Have you tapped the chassis in various places when it's on to see if anything changes?
On the flickering also.
Is the screen blanking or jumping or do you mean brightness changes?
You would have to find the out of spec voltage during the too-bright condition. There should be an easily measurable difference when it is ok and when it is not. Since it reverts to normal it does not sound related to the usual P1110 defect.
