I'm selling the original Matrox MXO video display device, in good condition with box and all cables.
This is not an MXO2 unit -- it has no inputs, only DVI and component/SDI out. What it does is take a DVI signal from your video card and convert it to an interlaced video signal for monitoring on an approved computer monitor. You can calibrate your monitor and have a fairly accurate HD image to grade with. I used this extensively on my Mac Pro with FCP7 and Apple Color before upgrading to an MXO2.
