Thanks very much for doing that Patrick.

Not a deal breaker I guess. If I had four of the display adapters I could just run the 4 way display with the advantage that 60Hz should then be no problem at all.

I might buy 1 UHD 30Hz adapter and see how that looks.

If the 30Hz is really a problem, I already have one 1920x1080 adapter, so I'll just buy a couple more. The non UHD ones are pretty cheap. Well even the UHD ones aren't that expensive.

Edit: my machine does already have DP and HDMI dual outputs so only one extra adapter is truly needed. I presume MHL-HDMI takes a regular HDMI input (Edit 2: yes it should be fine with HDMI on that input)
