Increasing toolbox and paintbrush icon size

[Theo11]

I am using Win10 Pro and Gimp 2.10.34. I have tried all the Themes and Icon Themes including custom size to huge, to try to increase the toolbox icons to a useable size, all to no avail. Somewhere, it said something about screen resolution possibly effecting the overall layout and the toolbox icons. Very frustrated, any help would be appreciated.

I am assuming this is a 4K display. I am a linux user and hopefully a Windows user with a high density monitor comes along.

However, this comes up with regularity. There is a bug report about it https://gitlab.gnome.org/GNOME/gimp/-/issues/6832 and that is from two years ago. It does say in there, that Gimp 2.99 has improved hiDPI support. The current version is 2.99.14 (2.99.16 expected soon) https://www.gimp.org/downloads/devel/ and for Windows that will install alongside your existing Gimp 2.10

You can change the screen scaling https://answers.microsoft.com/en-us/wind...6ff68021fd

edit: that is
This PC > Local Disc (C: ) > Program Files > GIMP 2 > bin, right click on gimp-2.10, open Properties, click on Compatibility. On the settings options select: Override high DPI scaling

*** big caveat *** Be very-very careful, you are liable to change the size of **everything** making Windows difficult to use. Not that easy to get back out of a 200% zoom. (at least on my Win10 VM).

----EDIT---

It might be worth checking the display resolution settings in Gimp preferences match the actual resolution of the screen/monitor.

Even if the ppi setting is correct it is possible to set a 'false' value that increases the size of the icons.
In Edit -> Preferences (1) Icon Theme change from Custom icon size to Guess icon size from resolution. (2) In Display Monitor Resolution choose Enter Manually. Bump that value up by a multiple, x1.5 or x2 example: https://i.imgur.com/BEZI7ZV.mp4

Not the best thing to do but it is Gimp specific.

If you need to change the font size in menus and other icons there is a plugin that helps see: http://gimpchat.com/viewtopic.php?f=11&t...10#p261235

Thank You for responding so quickly, I do appreciate it. I am using a Dell Precision 7760 laptop with a second LG 24 inch monitor, unfortunately not 4K. It is set to 1920X1080 as max resolution. 
I opted not to try messing with the windows setting in Gimp but may still try.
I did try the Edit/Preference/Display Resolution/Manual which was at 256X256 changing it did nothing, yes I did hit OK. So setting Icon theme to Color/Guess icon size from resolution and in Win settings increasing the scale/layout for this monitor to 125% the tool icons are large enough to work with but the brush sizes or pattern squares they are still too small to work with.
Thanks again for your help!

I am on a laptop with Windows 10 and a 4k screen. The link below shows lines which I added to my gtkrc file in order to control the toolbutton size, menu icons, dock tab icons, etc.

Dell Precision 7760 has three options for screen: 17.3-inch, 2 HD @ 1920 x 1080, 1 4K @ 3840 x 2160 with respective densities of 127 ppi and 255 ppi.

If Gimp is set up for 4k (laptop 255 ppi) and the second monitor is HD (??? ppi) then they will display differently

Gimp set at 256 ppi ?? What does the calibration setup in Gimp say ? That is physically measuring the rulers in the display. It is probably correct but worth a check.

Then it depends on which monitor shows the Gimp toolbox (I think, I do not have a dual monitor setup, only a lowly HD laptop with 158 ppi screen density)
