I am using these as smart devices for big screen TVs. They work well with 1080i, 1080p and 4k TVs.  I do not use them for gaming other than Solitaire.  I can stream 4k movies and get 7.1 sound when using the optical cable out to a 7.1 channel receiver.I bought 3 of them. They all worked well although one shipment came with a wired keyboard, mouse, a USB WiFi plug and the BIOS was on the current software level the other two did not. You will also need a display cable. None of these can be upgraded to Windows 11. I knew that going in and will probably run unsupported because they are not critical computers to me.=========================update=================================================One of the three has failed just after 90 day warrantee. looks like a power issue with the motherboard. I'll use it for spare parts.
