Monitor Scanlines/Image Persistence?

[Skeletore]

I bought an ASUS IPS MX239 LCD monitor a few months ago, and have noticed that there is what looks to be horizontal scan lines appearing from the left side of the display, but only the left. (They look like they are traveling vertically ever so slowly, dim, but noticable.)

I also noticed that after using it like this for a while there seems to be a bit of image persistence, comparable to a burnt in image, but throwing on different images on screen for a period of time will remove the static image. However the scanlines remain on the small left portion of the screen. I'd say it covers 1/5 of the display.

I have tried multiple devices in multiple inputs on the monitor but the problem persists no matter what device i'm using. I have also left the monitor off for about a week but still no luck. I'm now trying some other tips I've seen online of leaving a solid bright white screen on the display for a few hours etc.

Does anyone have any suggestions on how to fix this issue? Or should I just bite the bullet and send it in for repairs?

I just noticed something. My monitor has 2 HDMI ports and one VGA port. However my GFX card doesn't support VGA, so I used a DVI adapter with the VGA cable I had and tried that with the monitor. My GFX card read it as a CRT display, the entire screen was tinted red and didn't show any other colors, but the scanlines I had been experiencing were gone and it looked completely normal besides the color.

The weird part is, if I have nothing plugged in and turn the monitor on it shows the blue screen looking for a signal and I see the scanlines again. Is this some kind of color issue where part of the screens pixels aren't registering a certain color or something?

Well, the red, green, and blue, are separate colors... so, maybe it is possible that just the blue circuitry is bad. The part where you are seeing it in the menu without a signal, seems to confirm that... so good job on finding that!

However, just to be sure, try using an HDMI cable before you file a warranty claim.

Basically, I always suggest to people that they never use VGA on any device they own, if they can help it. It has poorer quality. Basically, only use digital: DVI-D, HDMI, or Displayport.

1a. If your video card has a DVI plug (which you said it did), then just use the DVI to HDMI cable that came with your monitor.
1b. If your video card has an HDMI plug, then just use an HDMI cable.

Ya, I had used both, I was using DVI-HDMI when the issue first came up, then I tested with different HDMI cables hooked up to a PS4 and a PC but the same issue, then i tried the VGA cable. But it looks like I'm going to have to file that warranty claim.
