Hi

Thanks for youe help, I can purchase one from http://www.dabs.com/productview.aspx...avigationKey=0

Anyway one of the reviews states:

Mode 2560 X 1020 (2 x 1280 x 1024) only works at 60hz as is stated by matrox. However when tested with 2 x HP TFTs I found horizontal bars rippling up the screen. This was not a fault of the DualHead2Go unit but rather the TFTs and a poor signal from an nVidia 7300 GO based machine. Better cabling, helped slightly but not enough. These TFTs work fine at 75Hz but that is not supported.

I would recomend driving each of your existing displays at 60Hz from the machine you plan to use this device with before purchasing it. If the image quality is poor, then this device will only make it slightly worse.

I also tried two Samsung syncmaster 193T's with which work ok at 60Hz However once in 2 x 1280 x 1024, the image was shited right about 1cm into each panel. Moving the horizontal position as far as possible to the left on both the monitor and the display adaptor could not solve this problem. Again this issue was specific to the monitors I using but could happen to other users.

I am not familiar with refresh rates of anything, based on the information/review specified above, could someone reccommend me 2, 17 inch monitors, as I dont want the problem above to occur.

Thanks for your help
