Prior to downloading and installing Mac OS Big Sur, I was able to connect my 2020 Macbook pro to any HDMI monitor/tv. Specifically I would mostly use a Dell se2717 monitor. It would connect within a few seconds and there was never any issues. Once downloaded and installed Big Sur to my computer it no longer recognized any HDMI monitor/tv. I have tried different adapters to connect the HDMI cable to my USB-C ports; different USB-C ports with all the adapters; and tried every trouble shoot I could find from Apple, Dell, and various websites. Is there anything I can do to fix this issue?
