EVanlak HDMI dummy plug headless ghost display emulator premium aluminium PC (fit headless-1920x1080 new create a virtual second screen that actually does not exist. Use a dummy indicator so that the second (virtual) screen can be transferred to a Chromecast device. Works on remote computers without local monitor. The HDMI emulator with 1920 x 1080 at 60Hz lets the GPU believe that a monitor is connected, allowing HBCC to stay active. Sometimes HBCC is disabled if SSH into your mining rig prevents this. I'm not sure how much HBCC plays a role in other cards. The OSX Display Menu utility makes it easy to change the resolution. An HDMI connector would be useful in situations where you don't have another HDMI cable to connect to the card and want to use this GPU for something like cryptocurrency mining or BOINC work unit crunch.
