I have the above two monitors connected to a 2019 mac pro. They both have a habit of randomly disconnecting for a few seconds. Sometimes once or twice, sometimes half a dozen times, and sometimes for uo to 20 seconds. I found a post from 2020 where this was discussed but no solution was found. Both apple and acer bounced it to each other but no solution was found. The thing is I have had these monitors connected to an older mac pro and had the same issue. I have bought new power leads and HDMI cables. My current mac has two graphics cards. I have tried both plus having one monitor plugged into each. The problem continues. While typing this my other monitor is losing connection, 5 times. Literally the only common factors are the monitors. The newer KA270Hbmix sometimes gives me the 'no input' message and the older KA270 says 'input not supported' if the disconnection goes for too long.

Does anyone know if a solution was ever found or do I have to buy new monitors?

Many thanks
