maybe it's the driver, usually happens when u install a new GPU (happens to me too)
if u want to display with the GPU, don't replug it during a session, u need to start the PC on with the cable plugged unto the GPU, or the GPU won't be considered as the main display by the computer.
supposedly a computer should detect the new hardware once u seat them correctly and them start them (though they will had small resolution, u can install ur graphic driver and it will adjust later on)
How would I update the driver without having display? Tried multiple cards also. Still no display
not the graphic driver dude, those can only be installed once the PC recognize your hardware
when a new hardware installed they will show up at device & manager, considering this is a GPU, they will automatically got detected when ur PC start, so u CAN'T change them midway by turning on the PC with the cable plugged to mobo, then replugging it to the GPU, i tried that so many times with my GTX 1050TI and it won't work.>>> U had to plug ur HDMI to the GPU before u turn on your PC! don't change em mid-session <<<
