Mac Mini black screen after apple logo

[laskwith]

Hi all - I am trying to hook up my mac mini (late 2014 intel, Big Sur) to an HP monitor and I'm having a really strange issue.

For some reason I can't get this combination of mac and monitor to work together - the apple logo startup screen shows correctly and then as the bar is nearly filled the monitor itself flickers for a second and appears to crash/shut down, it's power light turns off and I can't get it to display anything from any of the inputs unless the monitor's power cord is removed for 10 seconds and it's reset.

I can't seem to narrow this down to one faulty component - the mac works perfectly when plugged into my TV, the monitor works with every other device I've connected, and I've tried different HDMI and mini displayport cables both with the same results. I'm thinking this must be an issue with my monitor but it's strange that every other device I've connected to it (windows PCs, iPad, etc) all work no problem.

I've tried booting in safe mode and resetting PRAM, same issue.

Has anyone seen something like this before? Any advice would be super useful before I give up and go and buy a new monitor haha

Thanks!

Might help if you specified what make/model HP monitor it is you are using.
Also what version of Big Sur you are running.

Yes sorry! It’s Big Sur 11.1 and the monitor is an HP w2207h - pretty old at this point but like I said I’ve had no problems with any other kind of input on it which makes me hope there’s some setting on the Mac that’s throwing it off somehow?

This probably won't help but...

Can you turn on the display BY ITSELF (computer OFF), and use the internal onscreen controls to do a factory reset?

Another thought:
You're connecting to the display's HDMI port, is that correct?
It also has a VGA port, is that correct?
If nothing else works, you might try connecting from the Mini's thunderbolt port to VGA using a:
Minidisplayport (Mini end) to VGA (display end) cable.

Thanks for the suggestions - unfortunately a factory reset didn't seem to change things. I don't have the correct adaptor to try your other suggestion but am pretty sure at this point that this is just something to do with my ageing monitor being picky and not liking the input from the mac - probably a good excuse to look at getting something a little newer.

Thanks again for your help though!
