Blurry Screen

It started a few weeks back after our most recent show finished we have a break and I came in one day to find that the screen was blurry. I figured it was no big deal and reinstalled the hog software hoping it would fix it and it did temporarily. I came in again today to find it more blurry and worse than before on the wing 4 and my two main screens. Don’t know if this is a software issue seeing as it’s on all 3 screens or if it’s just a screen issue. Do I need to replace the screens or is this a bug?
