Question about LG Flatron L1951S 19" LCD Flat Panel Monitor
I would actually suggest to consider the drivers of your graphics adapter.
Try upgrading the drivers of your video card. If you already have the most recent ones, I would UNINSTALL the display adapter in Windows Device Manager...and reboot the system once more.
If necessary, I would roll back the driver to a previous version.
I suspect that perhaps there may be an issue with the refresh rate or something along those lines coming from your card to your monitor. Perhaps some kind of ratio issue?
One thing I would do is definitely check the manual to your monitor and find out what "Normal" really means. THIS is what I found:
"Lightview hot key
This feature lets you easily select the best desired
image condition optimized to the environment
(ambient illumination, image types etc).
• DAY : Bright ambient illumination
• NIGHT : Dark ambient illumination
• TEXT : For text images (Word processing etc.)
• MOVIE : For animation images in videos or movies
• PHOTO : For pictures or drawings
• NORMAL : This is under normal operating conditions"
So looking at that, I am led to believe that your monitor is switching viewing modes somehow. I would inspect the button that would potentially change these modes and make sure that it's not jammed somehow. It could very well be the problem causing your other buttons to be inoperable. (If it's somehow being held down by a foreign object for instance.)
Click HERE for the manual. (Don't enter your email addy. Just click the download button.)
That's about all I can really see as a problem without seeing it personally.
