Hi @philiparvidsson
Thanks for the issue.

I need some more information:

• What is your screen DPI? You can check by open Windows Settings > System > Display, scroll to the Scale and Layout section.

Thanks

@d2phap

I will check ASAP (not currently at that computer). It's a Dell U2718Q monitor, 27-inch 4K panel with scaling set to 200% in Windows.

Thanks, I will add this feature in the next release

Hi @philiparvidsson
Your feature request was implemented.
The size of grid will be auto-adjusted by DPI scaling number.

You can try the latest build 5.1.7.18 here: https://imageglass.org/moon

@d2phap, that's great. Did you also adjust the size of the image according to DPI scaling? 100% zoom should also be scaled according to DPI, otherwise 100% zoom will look tiny on high DPI monitors. I.e., not only the background should be scaled, but also the image.

The image size cannot be adjusted. It will be blurred, and the viewer should respect the actual size of image.

One example, you can compare the png image by Google Chrome and ImageGlass to see the differences.

@d2phap you should have a look at how windows photos app does it. it doubles the pixel size if dpi scaling is set to 200% to keep the image the same size on the screen.

Hi @philiparvidsson
Sorry but that is the big problem of Windows Photo app.

Reddit users complain its blurry issue.
PNG/JPG... are not like vector format, it's pixel-based format.
