When I attach an external monitor to my new Dell Precision I always get this and the monitor refuses to recognize video input. If I persist it reaches a point where the machine will boot but won't bring up a login prompt. I have to ssh to get in. And worst of all, it persisted after I remove the external monitor and am forced to re-install CentOS (7.6.1810).
