New Mac mini M4 Connection to Samsung 49" G9 Display

The Samsung monitor is saying it sense no connection. I am using a Micro HDMI which came with the monitor connecting the Mini with the monitor. Have tried unplugging all and waiting.


Is there a problem with using a Micro HDMI with the Samsung monitor (which does have a micro HDMI port)?

Mac mini (M4)

Hi Martin - Thanks for this response. The model number is: S49CG93*S

Well, that is a special model and it does indeed have a microHDMI connector. But that connector is the HDMI 2 input.


Have you set your monitor to use the HDMI 2 input? If your monitor is set for HDMI 1 (default) but you cabled into HDMI 2 you would indeed get a "no connection" message on screen ... due to no signal into HDMI 1.


Also check that the Input Port Version is set to HDMI 2.0 in your monitor's settings. Read the manual about where these settings are.



BTW, it would be much better to get a good, standard HDMI cable and use it with the monitor's HDMI 1 input. Most of the cables included with monitors, while they may "meet" the specs they are cheap cables. The "high speed" microHDMI cable that came with the monitor is only rated for 4K. Your monitor is an 8K gaming display. With this monitor you should use an 8K HDMI 2.0 certified cable like this one or better.
