I bought this mini PC for when my kid had to do remote school during the pandemic.  For that purpose it worked fine.  It was connected to a 2560x1080 (21:9 ratio) monitor.  I just replaced the pc with a Beelink mini pc with a more powerful cpu (ryzen5 5560u) and 16gb ram.  I was planning to use the Minis Forum GK41 in my home theater for digital music.  Here is my issue:  the Minis Forum GK41 will not display any video when connected to to an AV receiver - I have tried with both my Emotiva XMC-2 and Denon X1700H.  It also will not display video when connected to my projector (Epson Pro 6050 4k).  It appears that this pc’s HDMI port does not support HDCP.  I have an HDMI over ethernet transmitter/receiver on which the HDCP LED indicator is blinking when connected to this pc, which means the HDCP signal is either not detected or is not working properly.  I connected the new Beelink mini pc to my av processor and it works perfectly displaying 4K resolution.  In summary, if you want to use this with a dedicated pc monitor and do lightweight work, it works for that purpose (definitely no gaming - i.e. fortnite with low graphics settings gets about 8 FPS).  If you want to use the Minis Forum GK41 in any home theater setting where it will be connected to an av receiver, look elsewhere.  I contacted Minis Forum support with very specific details and they responded with a single sentence answer: “have you tried with another projector?” I’m not sure whether their support team is not aware of the HDCP issue or are simply not up to speed on their product and limitations. At this point, I have little confidence in Minis Forum and their products as a result of this and would recommend other brands over this one.
