Once per day or so, my VA1938wa goes black and in the middle it says in a blue box with white letters saying "Out Of Range". To fix this, I have to force restart my computer by holding down the power button. I tried unplugging the cables and replugging them in, but that didn't help. It could be a graphics issue but I doubt it. My graphics card is the AMD Radeon HD 7850 with 2 gb of ram. If someone can help me solve this issue, that would be awesome. Thanks
