Good day sencan, Most recent Graphics Cards do support 6 Screens. Normally 4 of those you could connect direct to the Card and for 6 screen supprot you would need to make use of an MST Hub. Since Your card has 2 DP1.2 outputs, you should be able to make use of 2 x CSV-5300H and connect 6 screens to that. Since an MST Hub is an active device please make sure to use passive cables / adapters to connect the screens to the Hub. Connect screens 1 by 1 and check if resolutions / frequency is set to 1920 x 1080 at 60Hz before connecting the next.
