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:
