Hi, I am using a Benq EW2780U display on my 2014 Mac mini running Catalina 10.15.7 and teh machine is reading it as a 61 inch monitor and not a 27 inch monitor as it is. As a result, the type is absolutely TINY.
Can I solve that somehow?
Try a different cable - some cables are not the same between each other.
Also try changing your monitor settings such as turn on/off HDR, HDCP, etc...
