LG 4K Red Flickering on PS Pro

[D10DGI]

Hi all, looking for help on a very annoying problem. I have the LG55UM7400, works great with Sky and my PS4 Pro. I only play Fifa mainly and seem to run into an issue when playing the actual match, I get random red flickers that may last a second then disappear, it’s only on one side of screen aswell. These flickers only happen when I play the actual match, in menus, etc there is no problems. Tried all sorts of messing with settings on ps and tv but still nothing
