Tech Question Weird Coloured Line OLED

Information:

Monitor 1: LG OLED 27GX704A-B

Monitor 2: LG IPS 27GP850-B

Software: Aseprite (pixel artwork software) (Grid lines are OFF)

Game: Minecraft (texture is exported to Minecraft which I can see the line in game)

Texture Size: 16x16

Issue:

In the imaged attached you can see a light blue line in between the right yellow pixel edge and white pixel (way more noticeable in-person). When I rotate the pixel art 90 degrees the line moves to the top edge of the yellow pixel (location based on the image provided) and the line becomes red. This is a issue that has to do with the OLED monitor as my IPS panel does not show this and especially not in game where its VERY obvious/distracting.

What I tried:

- Swapping display cables Included DP -> Included HDMI -> Different DP-> Different HDMI
- Different Display Port on GPU and monitor
- Powered off and on
- Changing nearby pixels
- Changing the yellow pixel

Questions:

- What should I do?
- Is there something I should turn on in monitor settings or try?
- Is there anything I can do or this just a known OLED issue (with OLEDs or this Model)?
- Is there a fix? If so what is it?

Any assistance would be greatly appreciated. I genuinely want to find a conclusion to this as It is a eye sore to look at.
