Win10 with Eve 4k and a Full HD monitor - problems of the OS

This is not 100% Eve or Spectrum related, but it popped up with my new Spectrum and maybe others are in a similar situation or have already solved it…

As the title states, I am using my 4k Eve and another Full HD monitor with Win10.
The Eve is scaled by 175% while the other one stays at 100%. I can’t use the 4k Monitor at 100%, since everything would be way to small :sweat_smile:
Most of the apps are working fine with this setup, but there are issues with some apps or some combinations.

1.) some apps look heavily oversized on the Full HD monitor, like they were also affected by the 175% scaling (e.g. FastStone Image Viewer or the “magnifying” feature of the screenshot tool Monosnap)

2.) I set Destiny 2 to run on FullHD on the Eve. There are several issues: I get thrown out of the game window several times before being able to play. Also the second monitor, where I normaly place either my browser or discord, only shows the wallpaper - sometimes the wallpapers of both screens oddly arranged - and nothing more.

  1. is obviously some compatibility issue of win, the app and the two resolutions, whereas 2. seems to be an issue with the changed resolution itself.

Did anybody experience similar issues? Does anybody have a solution?

Yeah, that is windows doing its job :confused: . I had my two cents for this topic:

Maybe this changed with win11, but you’ll probably have to live with these problems if you want to run two resolutions.

The “oddly arranged” settings happen, if the desktop resolution is different form the ingame resolution


thanks for your feedback. I did not want to replace the Eizo screen, but looks like sooner or later I have to :see_no_evil:

Windows is notoriously bad about dealing with multi-monitor situations - especially when you’re using mixed resolution environments.

If you have a nvidia card, you can enable Dynamic Super Resolution (set DSR - Factors in nvidia manage 3d settings panel to 4.00x). This will let you set your 1080p monitor to 4k, and means that both monitors run at the same resolution. This will eliminate the weird different screen scales when moving windows between monitors.

Play in fullscreen windowed (aka borderless) mode when possible.

If your card can’t handle 4k gaming, some games allow you to scale down the render resolution (so it renders at 1080p and then upscales to the 4k display).

If the game doesn’t have that feature, you can try getting windows to scale it for you:

The point is to keep the monitor resolution at 4k, and scale the game to fit it instead. This avoids the windows issues related to resolution switching in a multi monitor environment.

Obviously it won’t look as good as it would have in native, but this can avoid some of the headaches that comes from resolution switching in a multi-monitor environment until Windows realizes it’s not 1999 anymore and people actually can afford more than 1 monitor.

To be clear - you’d change those DPI settings for the game you’re trying to play, not for chrome. I just used that as an example =P


thanks a lot! I did not know about that nvidia feature - going to test that right away!
your suggestions sound really promissing, thanks a lot for sharing!

Welcome! The best solution is to just have a video card capable of 4k gaming, so you don’t have to do any of the scaling “hacks”.

I know price wouldn’t be an issue (anyone who can afford a spectrum can afford a card to drive it, and really should prioritize their money on the card over the monitor if they can’t afford both), but I realize not everyone can get their hands on the new cards yet due to availability.

Fwiw, for games, the “System (Enhanced)” DPI-scaling mode is overkill while it sometimes affects performance noticeably. For games, just “System” should be used, not “System (Enhanced)”. The “Enhanced” part corresponds to that Windows tries to render text (only possible if the app renders text via GDI) at full native/desktop resolution while displaying user interface and graphics scaled.

But actually, both “System” and “System (Enhanced)” are unneeded because Eve Spectrum has built-in pixel-perfect (integer) scaling and DPI scaling is unneeded as a way for scaling. Just set the in-game resolution to FHD and enjoy high performance with zero quality loss compared with a Full-HD monitor of the same size. Make sure to switch the game to exclusive full-screen mode. If the game does not support exclusive full-screen mode and only supports so called borderless mode (“Windowed Fullscreen”), switching Windows to the in-game resolution before running the game is needed for utilizing the monitor’s own scaling.

Only if you’re allowing resolution changes. These suggestions were a way to let him keep the monitor at 4k resolution while rendering at a lower resolution if his card can’t handle 4k gaming. This would be to avoid some of the windows glitches that result from resolution switching in a muli-monitor environment (windows moving weirdly/disappearing on second screen, etc).

Ah, ok, good to know. I used the enhanced mode for everything because it’s what seemed to look the best originally when working with older apps that didn’t dpi scale properly, so just kept using it when trying to make games scale too before getting my new video card. I never noticed a performance issue doing this, but I also don’t really play competitive shooters or anything.
