[ovirt-users] Testing 2560x1200 from tablet and Opaque

Hello, I have a CentOS 7 VM on oVirt 3.5 configured as desktop. What is the maximum display size it can get by default without particular customizations? In my case I'm testing from a 12.1" android tablet connected over wifi+openvpn and Opaque app. In Opaque I have a setting called Sync remote to display resolution My tablet resolution is 2560x1600 (btw I don't know if I can change it in Android scaling to any other resolution....) If I mark the setting above it seems it crashes If I deactivate it, I get a small window in upper left corner. I can change VM resolution up to 1920 and I get a bigger window, but I cannot go full screen for example... Anu advise at oVirt side to configure a bigger display size available? My VM has both oVirt Guest agent and spice vdagent installed ad active. Thanks in advance, Gianluca
