create a virtual second screen which does not actually exist. use dummy display so that can cast the second (virtual) screen to a chromecast device Works on remote computers without local monitor1920x1080@60HzEDID emulator plugstricks the GPU into thinking there is a monitor attached to allowing HBCC to stay active. Sometime HBCC will disable if SSH into your mining rig will prevent that from happening. Not sure how much HBCC has a factor on other cardsOSX utility Display Menu makes changing resolutions easysurprisingly has plenty of modes not only through the typical 4K (3840x2160) but true 4K (4096x2160) with refresh rates from 23hz to 60zDummy plug would be useful for situations where you don't have another cord to connect to the card and want to use that GPU for something like cryptocurrency mining or BOINC work unit crunchingMonitor connection is a great way to run a computer headless and get 1080p video via a VNC service no need to download any software or configure the unraid server just plug in adjust resolution and connect.
Works great as intended. Gives desktop a screen so it can remote into it without having a monitor constantly attached and on
