Runelite: Runelite not going fullscreen on second monitor

[TBBRKCK]

When trying to use runelite on my second monitor it won't take up the full screen, it leaves areas on the left and right and bottom where you can see whatever is open behind it.

[eEQK]

Have you tried that?

[TBBRKCK]

Just tried it, didn't make a difference

I've run into a similar issue, possibly the same one. When I try to maximize the client on my secondary monitor, it only goes as big as the resolution on my primary monitor. Custom chrome is disabled.

well for one, you aren't logged in

[TBBRKCK]

I'm not logged in because it makes no difference if I'm logged in or not

[eEQK]

Just to make sure, have you tried what Ive shown on the gif while logged in?

[raiyni]

pretty sure they are talking about the actual window size, not the ingame size. That sounds like a windows explorer issue after changing resolution/monitor settings.

[TBBRKCK]

Yes I've tried it while logged in

[TBBRKCK]

Yes raiyni it's the window size. Both my monitors are identical and the exact same resolution/settings

[raiyni]

This usually happens if you change resolutions or plugin a new screen without logging out of windows.

same Issue here, can confirm and reproduce. window size of runelite is only the size of 1st screen if in fullscreen on 2nd screen, not filling the whole screen like desired.

I found that setting my monitor to be the main display, instead of my laptop screen, in the "display settings" fixed the issue.

Using NixOS and can reproduce issue. I have two monitors, and RuneLite will only maximize it's window on the primary monitor and not my secondary.

[deathbeam]

Did you tried without custom window chrome?

[sleibrock]

@deathbeam that corrected it for me, never knew about the setting. Thank you!!

Can confirm this issue, with or without custom chrome window. Only uses primary screen's resolution to maximize the window.

[v0idp]

chustom chrome windows didn't fix it either for me.

I believe this may be the issue here as well: https://github.com/runelite/runelite/issues/3279

I can't get RuneLite to go full-screen on my second vertical monitor. It tries to go to a horizontal full-screen. It must be pulling my main monitor's resolution, rather than the resolution of my vertical monitor.

I have two UHD 3840x2160 monitors: the laptop screen recommends 300% scaling and the external monitor recommends 150% scaling.

• If I set my primary screen to be external monitor then maximize works on both outputs.
• If I set my primary screen to be the laptop and set 150% scaling then then maximize also works on both outputs.
• If I set my primary screen to be the laptop and set the recommended scaling options, maximize only works on the laptop screen

I am still encountering this issue after updating to launcher v2.1.6.

A workaround that I have been using is to have RuneLite maximized (with this bug) on my third monitor, then using a hotkey to move it to my second monitor. After doing that, it will be maximized until I move the window again.
