Hi,
I have an Elo touch screen 15" monitor on my Tormach mill thats giving me trouble. This monitor came from Ebay clamed it was working fine. Some days the monitor works fine all day, other days it looks like the brightness is cranked up all the way and the contrast all the way down. When its in this condition the screen does not appear to be refreshing properly as you can see traces from the pointer. I have reloaded drivers, changed cables, relocated cables, tried monitor on different computor, took it apart cleaned and checked all conections and still no luck. Most shops will charge $100.00 bucks just to look at this thing before starting work. Any thoughts? (the USB touch screen part of this monitor works great)
