Guild Wars 2

Hi Folks,

Been searching for another post with my problem, can’t seem to find one.

When left or right clicking and holding to reposition the camera view, the screen goes a hazy green (I can still see the GW world) and my character disappears into the bottom right and the zoom goes far out. It’s quite wild. The game is unplayable because I can reposition the camera.

Note: This only happens when the game resolution is at 4k! Both 1440p/1080 all is well. I’ve only recently come back to the game, so this might not be new

Troubleshooting I’ve tried:
1. Reset Graphics levels – tried all low – doesn’t make a difference
2. Tried different resolution – This works, but I want to play at 4k!
3. Updated drivers – no change
4. Reset user controls – ?
5. Updated mouse driver using Razer utility
6. Tried different desktops
7. Tried different monitors

Hardware – I’ve tried this on two machines using latest Nvidia Drivers, one was using a 960 and the other a 1080. I also tried 2 4k monitors a Samsung and an LG. I was very convinced it was hardware related, but I used two different computers and displays, different mice (both Razer).

It’s wild that this graphics bug only appears when attempting to move the camera with the mouse.

Figured a couple things out. First, I’ve been attempting to play on an LG 40UB8000 which is actually a TV. The problem appears to be the fact that the LG only supports 4k@60Hz when in 4:2:0 chroma.

This hasn’t ever been an issue for me in the past with other games, but GW2 plays fine (other then the delay) when at 4k@30Hz 4:4:4 chroma on the same TV. I don’t play competitive, and the LG has treated me well in the past.

I’ve scaled back to 1440p and will probably end up picking up a newer display in the future. Still would be cool if the Devs could fix it though!

I have the same issue with 4k today all of a sudden.

Windowed mode no issue
lower resolutions no issue
other games no issue at 4k

Wiped Local.dat problem stay
updated nvidia drivers problem stay
ran repair problem stay

Reinstalling game now but i dont think this is going to sort it.

Did not sort the problem to reinstall and i tried to screenshot the problem, but the screenshot is not affected by problem.

So that is a very odd bug that can now be added to the list of err bugs with this game.

I hope you can sort it.

(panning camera at 4k green screen and only showing left side of picture stretched)

Problem sorted.

For some off reason my screen was set on 4:2:0 i put it back on 4:4:4 and the problem was gone. I dont know why my screen was set like that, but i did reinstall the graphic drivers. But that was after detecting the issue which means it must have been set on 4:2:0 by windows perhaps during last update i just dont know. But that update was last week so this remains a mystery.

(perhaps an update to the samsung tv disabled UHD color through the HDMI which then made windows go 4:2:0)
