I need 2 screens for a Hurco BMC-20p with Ultimax 3 controller. The originals are not working, I have VGA interface cables,I am currently using 2 old computer standalone monitors. I got 2 screens, but the vertical frequency is wrong, so the image is rolling. I would like to get 2 screens, 10.4 or 12 inch to fit the standard console. Anyone know where I can get them. There are a number of outlets who can supply, but are charging too much.
