I have a 23 inch LED monitor (AOC) which is about 5 years old maybe more . It has intermittently developed a fault which I've noticed recently & shows up most on a dark coloured image as I hope you'll be able to see in the attached photo ( the light blends into the dark smoother on screen than what it appears in the photo ). The problem can suddenly appear or disappear while you are using the machine or is there from start up to shut down , or not . Last day or two it's there all the time though. Best described as a light greenish patch in the bottom left quarter which causes a screen mesh or gauze type effect on that side of the screen, rather like what and old CRT monitor or TV picture looks like when viewed really close. It shows up worst on dark backgrounds but is obviously affecting any graphics on the screen . Other half of the screen looks normal .
I'm assuming it's the monitor at fault rather than the graphics card because it does it before windows starts on the dos screens . Also if I shut the PC down and just power the monitor up on it's own and disconnect the cable connecting it to the tower , the fault is still there on the black screen showing the no signal message . The drivers for the monitor are up to date it seems . I had it connected with a VGA cable but am now connected to the DVI so I don't think its a connection fault either. Has anyone a solution or is the monitor no good ?
