I have an LG flat screen monitor. It displays Google Chromecast and other device inputs just fine. However, my Mac Mini was going in and out for a few days; it would display for a few minutes then go blank (no signal), the display again, then go blank. Now, it doesn't the Mac Mini does not display at all. Mind you, the other devices still display on the LG just fine. What's going on? Why does the Mini have so many screen display issues?
My traded M1 mini and now my new M2 mini pro have no display issues with my 32-inch LG 4K UHD display using the HDMI port on the mini and a Belkin High Speed 4K UHD HDMI 2.1 cable connected to the LG display.
Same solid result: BIg Sur, and Ventura 13.2.1.
Get a good quality, certified HDMI cable preferably under 1 meter ior less in length. Generic HDMI cables tend to cause issues with computers.
Also, what model LG monitor do you have as LG makes a myriad of displays, even older versions of current models.
