XB241H factory oc white lines
Posted: 29 Dec 2018, 09:19
So I finally upgraded to 144hz, and it looks amazing !
I've got the XB241H which can be overclocked to 180hz (through the on screen display), but when I do so, bright white horizontal lines maybe 1 pixel or half a pixel wide appear every 4 or 5 pixels. They're easy to see to the left of the screen but gradually fade out to the right, and become invisible roughly halfway through the screen. On top of a fixed image like this website's background right now, they almost look like a cool filter, but they get rather annoying on videos or games.
I tried making a crude reproduction of the effect : http://oi67.tinypic.com/98fry8.jpg look at this in 50% zoom and it almost looks like my predicament. The real lines are somewhat dimmer and they all have the same brightness, so they're not as noticeable as the example, but that gives you a rough idea.
Going back to 144hz reduces the lines' brightness, but they're still there. Just so dim they're almost unnoticeable. I found a thread filled with people having the same problem with the same monitor and it seems like this is something that happens a lot with high refresh rate TN monitors. (here it is http://www.tomshardware.co.uk/forum/id- ... oblem.html )
What's up with this ? Is it widespread ? Does it have a name ? I don't reckon there's any way to fix it ? Any idea why higher frequencies make it worse ?
Edit : I bought used so I've got no idea how it looked fresh out of the box.
