Viewsonic Monitor goes RED
I have a Viewsonic PF790 monitor. After being on for a while, it will slowly start to go red on me. the picture expands horizontally also. Sometimes it happens after 15 minutes, other times it works for several hours. If I shut it off for a few minutes, it works OK again. then it will slowly go red and wide. Any ideas?? TIA- --seeing red |
