2015Monitors forum

An Ultra Bright monitor may reject interlaced video signals like 60i and only accept progressive formats like 24p on its HDSDI input.
When the graphical configuration menu disappears on an Ultra Bright monitor, pressing the Menu button combined with arrow buttons repeatedly may briefly bring it back into view for troubleshooting.
Testing both HDSDI inputs on the monitor can help determine whether the issue is with a specific input port or the overall video format compatibility.

The root cause of the missing graphical menu remains unclear.
The monitor in question was described as a rehoused Boland unit, suggesting the behavior may be specific to that version or manufacturer's software implementation.
The workaround involved changing the video source output rather than modifying monitor settings, so the actual factory reset capability was never tested.
