So to have resolution matching work, the sender and the receiver must be able to support the resolution(s) being requested by the receiver. One thing to test is to connect without resolution matching, and then go into your display settings and see if you can manually set the resolution. If so, Remote Boost should be able to do it. However, if you have a display attached to your sender that is 1920x1080 and you are trying to have it match a 4K resolution, it will fail because it can't do more than 1920x1080. You could have your sender go headless if you have an NVIDIA quadro card. The embedded EDID in Remote Boost does support 4k but is limited on wide screen resolutions, like the HP 38C display. There is a property in the rgsenderconfig file for headless. Search on EDID. Remove the # and change from zero to one. Save the file. Make sure you have admin privileges when opening the file to make the modifications. After saving the file, restart the sender service to have the change take effect. The property will not load if Remote Boost sees a display attached or another EDID file. I usually do a reboot without my display attached when doing this.
