Thanks you, I will test with virt-manager. I'm using a windows 8.1 installation. Seems like it need wqhl drivers, and The driver I found [1] did not work for this resolution.
Maybe I should test compiling seabios as commented on that blog Thanks you [1] https://supervacuo.com/2014/sep/28/windows-81-qemu-custom- resolutions-qxl/ -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1054558 Title: 1366x768 resolution missing Status in QEMU: New Status in Debian: New Bug description: I use ArchLinux with QEMU 1.2.0. I found that 1366x768 resolution is missing, even if I use -vga std or -vga vmware. I think that it is necessary to patch it into the source. Also, why not add a command-line option to specify custom resolutions without patching the source? (I know that VirtualBox has a hidden option to add any resolution.)
