I have 3 Acer B223w 22" monitors. They WILL NOT work at 5040 x 1050 even though Matrox said that they would. I bought these because of their referral!
I can only get to 3840 x 800. Doesn't look bad but not like it should. The monitors get an image at 5040 x 1050 but there is a floating box that says "input not supported"
Any thoughts? Can the monitors be adjusted and I am missing that?
So, if you get an image then the monitors _do_ work. My Samsung monitors also get a similar box when I switch to 57Hz mode, but I can get it to go away by pressing the "menu" button on my monitor. Maybe you can do something similar.
