Purple screens on two separate new monitors within week of use?

HP Recommended
HPN246v, HP24yh
macOS 10.15 Catalina

About 3 weeks ago I purchased a brand new HP24yh desktop monitor from staples. Within a week, it started displaying a purple screen upon startup or waking up from sleep mode, which started happening more and more frequently. This was using the factory provided HDMI and power chord with a Mac mini.

Once the purple screen started happening about ~25% of the time on startup, I went back to staples and exchanged it for another brand new Hp monitor, this time the HP N246v monitor (24yh was out of stock). 

I set this new one up with my own HDMI chord (one wasn't provided with this monitor) and within a day of use, I turn it on and the screen is purple again.

The purple goes away when you turn the screen off and on again, but it continues to happen with increased frequency and I am worried I will end up with a permanently purple screen. I also do not want to be getting a new computer monitor every two weeks. Is this a known issue with all HP monitors or am I missing something? Thanks.

Thank you for posting on the HP Support Community.


To get the answer to this question, HP monitors are not supported in a Mac environment. However, newer Macs use graphics with VESA modes and can display to most HP LCD monitors. To do this, connect the monitor to the Mac while the Mac is off, and then turn on the MAC. The monitor should operate at 60Hz. The INF and software for the HP monitor are for Microsoft Windows and cannot be run in a standard MAC OS environment.


Hope this helps! Keep me posted for further assistance.
