Monitors are expensive. Not only that but there must be a straight up answer other then, idk go buy a new monitor
Well he is correct. Off brand TVs are probably even more finicky then a name brand. So it may be just that, as in go buy a new monitor. Not that im saying that is the solution, recently ive been building a few custom HTPCs and using them on my Dynex 46 inch 1080p TV and there are no issues and that isnt exactly a name brand either. Hard to tell. Could be the input onthe TV, try a different input.
