I own a viewsonic GS790, i've had it for about 3months, the 1st 2 weeks of usage it turned off by itself twice but when i turned it back on right after i didn't see any problems, & it hasn't happended anymore, but my desktop color is black & there is a light white glow on the right side of all icons & on the bottom of the taskbar, is thi normal? i don't notice this glow as much in the day because of the sunlight but at night with on the lamp on i can really see it? & every few weeks on the lower right hand corner the monitor has a green glow when it's on a white background? anyone know why this happens, this problem also happens on my panasonic tv when it shows a white area it starts getting green, is this a problem with the crt tube? i asked for a rma, should i just get a refund?
