No blanking occurs when invoking the kernel with a video command-line option that includes an R flag. For example:
video=HDMI-A-1:1920×1080R@60
b
The Samsung SyncMaster SA850 is available for purchase at the time of writing and works well when using 1024×768 or half of the native resolution, but only if the following kernel command-line option is provided to force the resolution. ARM recommends adding this option to get the monitor to work:
video=HDMI-A-1:1280x720@60
(If you have a 3.10 based kernel, then replace HDMI-A-1 with DVI-D-1)
