No 1920x1280 resolution on Display Config (Lenovo Y50)

My new Lenovo Y50 has a display that is nearly twice as wide as it is high. So I would like to set the resolution to around 1920x1080 on the Display Config.

But aside from the maximum available 3840x2160, which results in a desktop with objects too small to be usable, all the remaining resolutions are not wide enough. The best available selectable resolution is 2048x1536 and results in black bands of unused screen space on both sides.

Is there any way to add an option near to 1920x1080 to the posibilities?

Suse 13.2.

I recommend staying with the native display resolution. Selecting any other will result in a display that is not sharp. It may be that you’ll need to force the DPI size with your desktop environment. It is also possible to adjust icon sizes too. Which DE are you using?

Thanks for the reply.
I am using KDE.
The Y50 comes with a 3840x2160 screen, which is glorious when I boot Windows 8.1 but hopeless so far with KDE. On the KDE Display Configuration screen I see a slider labelled “resolution” but only sliding it to the extreme right gives me an aspect ratio that comes near filling the screen but everything is tiny although finely detailed. Sort of like standing 20 feet back from a 32 inch monitor.

Why don’t you just adjust font and icon sizes

System Settings (AKA Configure Desktop) > Application Appearance

From here is is possible to adjust as you like.

Further to the above, it may be necessary to adjust fonts DPI (via ‘Force Fonts DPI’)

I figured there were work-arounds available.

But going through every App on my machine (Eclipse, Intellij, Android Studio, Web Browsers, etc) to tweek fonts is a daunting task. Plus who knows what happens when I plug in an external monitor after having changed the icons and fonts.

Then there are other issues such as it is awfully difficult to grasp the edge of a window with the mouse for re-sizing because the edges are razor thin.

3840x2160 notebook screens are becoming more common so many Linux users will be having the same difficulty. “Change all your fonts” will not be going down too well.

Thanks for the reply.

I don’t have display hardware with high-end native resolution to test with, but I winder if it’s just a case of this particular display not reporting its true size.

What is reported by the following commands?

xdpyinfo|grep dots

(I’m just trying to determine if this is a ‘display-caused’ issue, or whether KDE really does not cope sensibly with the high-resolution display.)

An interesting discussion on this topic:

xdpyinfo|grep dots

Well, based on 3840 dots/344mm * 25.4 gives 283 DPI (horizontal). I calculate 182 DPI (vertical). Did you force the font DPI in KDE (to 96 DPI)? You could try increasing the value as an experiment (eg 144).

Dropping the resolution is definitely not a solution for a obtaining sharp image though.
