Hi,
I am running 2 Sony G420's and overall they have been great, however I noticed about 3 months ago, that my primary monitor 1, has become blurry.
The wierd thing is, when I open explorer, the blurryness dissapears and it looks good again.;\
Close explorer adn the blurryness is back. I have altered all sorts of settings mulitple times, like convergence etc and still have the problem.
Do others have this problem? if so, how did you fix it (if you did at all?)
Cheers

Hi again,
Finally found a fix for my problem and also discovered that Trinitron monitor have a tendency to get bright with age..., learn something nwe every day :)
The solution below fixed my problem :)>>
__________________________________________
Problem: Sony Trinitron monitors with brightness too high. Also affects Multiscan G420 monitors and Trinitrons rebadged as Sun monitors.
The screens on Trinitron-based Video Display Units get brighter as they age. There is no Sub-Bright adjustment on these units, and they get to the point where the front panel brightness adjustment is set to zero, and the screen is still way too bright (blacks appear as grey). In extreme cases the retrace lines are clearly visible.
Solution:
Multiscan G420:
1. Set screen brightness control to some middling value (say, 50-70%).
2. Make sure colour mode is set to "preset", "easy", or "expert". This is done by pressing the menu button, and navigating to the toolbox icon, and then the "3-dots" icon.
Once done, return to the main menu.
3. Navigate to the "three dots" icon (a different one from step 2, above) and then the "head-and-shoulderpads" icon.
This is the "image restoration" menu. This function will only be available if the screen has warmed up, which takes about 30 minutes.
If it's not warmed up, this menu selection will state, "Available after warm up", in which case, you'll just have to wait, making sure the screen doesn't turn off in powersave, or screensaver mode.
Once warm, you can select "yes" to start the auto-calibration process. This takes a few moments while it samples different settings.
4. Brightness can now be set as desired.
Sun Trinitron displays:
These are much the same, but have a different menu structure, and button interface, but the icons are essentially the same, and the "head-and-shoulderpads" icon is entitled "colour return".

Interesting Trinitron tip. Though I've only seen monitors get too dark with age, even with everything set to max -- though most were not Trinitrons.
