I’m running Windows 10 in VirtualBox and I’ve installed the latest version (currently 5.0.14) of VirtualBox and the extension pack and everything is running smoothly except for the resolution - when I try to adjust it to anything above 1600x900 it just goes to 1152x864. I’ve reinstalled the guest addons multiple times and that isn’t changing anything. Then I enabled 2D and 3D acceleration and gave it the most VRAM it allowed me to, that didn’t do anything. So now I have a feeling my laptop (Lenovo T450s with i5 5300U) just isn’t capable of running both the host and guest at FHD… Does anyone know of a workaround?
Your Host-Resolution is:
xrandr
Please, what is FHD?
I guess FHD means full hd as 1920x1080 or 1920x1200. When I google for
that model it shows me a physical resolution of 1600x900 for it.
Do you want the higher res on an external monitor?
Please check output of xrandr as Sauerland told you.

Hi, here VBox with 128MB of Video Memory defaults to 1920x1080 on my FHD display and Plasma5 settings can go as high as 2560x1600.
The amount of Video Ram limits the (virtual) resolution available, according to the manual, so what is “the most VRAM it allowed me to”?
2D acceleration doesn’t matter AFAIK and 3D accel doesn’t even work in Linux hosts yet.

On the host 3d acceleration by virtualBox does not matter at all as on
the host you run your graphics card with the corresponding graphic card
driver of your hardware and not the VB tools.
In my own setup on the laptop which am writing from, I run a Win 10
guest with 3200x1800 (native resolution of the hidpi screen) without any
problems on a Leap 42.1 host which has Intel Haswell.
Memory on graphics for the virtual Windows machine is set to 256MB,
which is the maximum for a Windows guest.
