After overclocking my gpu (gigabyte gtx 1050 ti) based on this video https://youtu.be/dThCbyzSy84 and restarting my pc i turned on my pc and it turns on but displays nothing. After putting the hdmi cable to the mobo's hdmi port. It displays. The gtx 1050 ti is still on and working but doesn't read the hdmi cable. How to fix?
