Windows 10: Windows 11 update killed HDMI output to only monitor. How to fix?

My computer updated to Windows 11 and now I have no way to use my PC. I have been using a flat screen TV as a monitor and have had no problems for over a decade now. But after the update my computer no longer outputs an HDMI signal. I don't own a monitor that will interface with my PC since it only has HDMI out. I've been browsing this forum but have had no luck as any other similar issue is with the "2nd or 3rd monitor" not working. My primary is not working so I cannot update drivers or change display settings. What are my options?

Issue:

• One morning after regular updates my graphics card stopped sending signals to HDMI monitors that are bellow the resolution of 4k. The monitors, just shows no signal, when you uninstall the drivers sometimes, like once in 4 times it will catch
  the monitor, but if you restart the PC you will again get no signal. The monitors works perfectly with my laptop on HDMI. 3 Of the monitors are fresh from the box. The HDMI port works perfectly with my 4k TV. Tried switching 7 HDMI cables total. Reinstalled
  windows twice, video drivers several times. Currently using a display port for one of the monitors.

Sound output through 2 HDMI monitors (HDMI and DVI ports)?

Hi Community, here's the thing. I have two HDMI monitors, one conneced to an HDMI port and one to a DVI (both give sound, even the DVI) but I cannot make both of them give sound at the same time. Windows lists them both as one output source, and only the first monitor that I plug in first gives sound. If it is of help, I don't have a dedicated graphics card, they're both connected to the motherboard ports.
