Hello anyone, I have a Viewsonic VA2037a LED monitor, I've had it for almost 2 years and it is suffering from some odd splotches. It started about 8 months ago as one oily looking splotch in the lower left corner, At first I thought some food must've splashed on it so I cleaned it with a gentle alcohol based cleaner and that did nothing. I stopped eating anything at my computer that can splash but the problem has continued to get worse, It almost looks like it was exposed to high humidity that got under the screen but I keep my house very controlled (Temp and Humidity due to asthma) It is especially bad when the screen is primarily white (E.G. Exploring Far Cry 4's mountains or using Facebook etc.)

Whatever the problem it isn't fixed by cleaning the screen and I'm wondering if anyone has a clue what I should do. I built my PC's tower so I'm skilled enough to take the monitor apart if I need to but I would love to know anyone's thoughts on what may be causing this so I can avoid it in the future. I Googled Viewsonic Splotchy, cloudy, discoloration etc and found nothing like my problem, Most were dead pixels etc.

Here are some pics of what I see:

And here's one with the contrast and brightness adjusted to clarify the issue:

I think it will be an issue with some aspect of environment interacting with the layers of the screen, whereby the outer polarizer sheet only partially seats down onto the panel surface beneath. The effect is similar to film tint on glass where the trapped air bubbles haven't squeezed out completely. Some panel designs seem more prone to such a problem. I've seen some at my work where tiny insects worked their way in between the layers. We'd hope it shouldn't be possible for such to occur, but it can, see what seems to be similar in this topic:

As for what can be done about it, I have no clear answer, despite being a monitor repair tech. Problems regarding the internal structure of LCD panels are usually reverted to the manufacturers to sort out.

The VA2037a is not an expensive monitor, so getting someone to repair it (whatever the fault) is not likely to be financially viable unless it's still under warranty - it would probably not even be financially viable to buy your own parts & do the repair yourself. Your options appear to be:-

 

a) Ignore the problem

 

b] Dive in, dismantle it & see if you can find a repairable problem not requiring expensive parts & if you destroy the monitor in the process then move on to option c

 

c) Replace the monitor

@rqt I've tried to ignore it for 8 months and it's giving me migraines almost daily so it looks like I'll be replacing it, I work at my computer so I spend from 9am till 1am on it most days :( My last monitor wasn't expensive either (an HP FP7317) and it lasted for 14 years with no issues at all, Very disappointing and sadly no not under warranty anymore. Once I get my new monitor an ASUS VS278Q-P (With 3 Year Warranty) I'll definitely try to dismantle this one and see it I can find the issue.

@Platypus I do figure that's sort of the issue, That somehow air or moisture has gotten in there. That link's photos do look exactly like mine. I suppose if a repair tech can't explain the exact cause or how to fix it it's unlikely I'll ever find out exactly what was happening. Thank you for your time though :)
