You have three limits:I guess this is not directly related to the FW900, so hopefully it can still be asked here.
Has anyone with the Iiyama Vision Master Pro 514 (and maybe even 454) tried going above the 200hz vertical cap with displayport adapters? I have found multiple people saying they have reached above 200hz when lowering the resolution, but I believe they are all using old GPUs... not 100% sure though.
- horizontal refresh rate - monitor limits it, DAC does not
- vertical refresh rate - monitor limits it, DAC does not
- pixel clock - DAC limits it, monitor can do "infinite" pixel frequency
Older GPU's like last generation of GeForce/Radeon with analogue outputs had pixel clock limit at 400MHz.
I guess there are DACs with at least 400MHz or even more. My Delock 62967 does about 340MHz.
But you probably do not need very high pixel clock for >200Hz modes because they are typically so much limited by horizontal refresh rate that they do not need large pixel clock.
