Phaze Alpha: Phaze does not currently install a virtual display driver to emulate screens on headless computers and virtual machines. We will release a virtual display driver with future versions of Phaze.
If you connect to your computer on Phaze and only see a black screen, it's because Phaze is unable to capture a monitor from the GPU. This typically happens on headless machines or virtual machines. A virtual machine may be running Proxmox, iDRAC, or another remote access controller. That "screen" is generated on the CPU, so Phaze cannot capture it. On headless machines, the GPU is not drawing a screen because one does not exist. On headless machines, the options are:
Download a virtual display driver. We recommend this open source solution.
Purchase a hdmi dongle, like this one.
