Custom HiDPI resolution is not available

[asheenlevrai]

Hi :)

I tried to add 3360x1890 hiDPI but after reboot it's still not there.

(see screenshot) Any idea why?

6720x3380? I'm not sure that OS permits it and the GPU supports it. I'll try it on my computer, but I have no 4K display. The first line works – I see 1680x945 HiDPI resolution in the list.

On my GeForce GT640 with 1920x1200 display it works. What is your GPU?

I tried to get 3360 x1890 hiDPI (lighting icon). I read somewhere I should double the values in order to get the hiDPI resolution.

For now I have 4k (2160p) and then the next hiDPI res is looks like 1920x1080... Which is not enough. I need something in between... But hiDPI (keeping all my pixels).

The gpu is hd4600

Oups 🤭 I should have added 3780... Not 3380. will try to fix that

[asheenlevrai]

Still... Not much luckier when adding 6720x3780. I still don't get 3360x1890 hiDPI

[asheenlevrai]

OK...

This is what I get with HD4600:

While this is what I get with a Rx590:

I imagine there is no way to get a better hiDPI res with HD4600 then. FHD is half of 4K in both directions...

Sounds about right? Or do miracles exist?
