The first generation UltraBright monitor exhibits consistent edge image loss across multiple HD camera sources including the F35, Genesis, and F900.
The UltraBright generation 1 lacks an underscan feature that the generation 2 model provides to display full raster images.
Image cutoff appears more pronounced with HD down-converted signals and letterboxed feeds on 4:3 monitors compared to film camera video tap outputs.
The underscan mode found in UltraBright generation 2 menu settings allows viewing the complete picture by showing full raster, which can be combined with manual sizing adjustments.
Workarounds for generation 1 include using the monitor's scaling menu to shrink the image to minimum size, though results vary depending on signal source.
HD component video signals from certain camera bodies at specific frame rates like 23.98 fps may contribute to the edge loss issue.
Using the frame line generator on affected monitors compounds the problem by masking additional picture area beyond the existing cutoff.
A real framing chart is the most reliable method to confirm whether edge loss is monitor-related or signal-related.

Issue confirmed on first generation UltraBright only; generation 2 has underscan feature to address it.
Manufacturer inspection of the monitor found no identifiable problem despite user reporting.
Edge loss severity appears signal-dependent and may vary with different camera models and output configurations.
The workaround of scaling images on generation 1 requires manual adjustment and does not permanently solve the problem.
Disagreement exists whether this is a fundamental design limitation of generation 1 or a configuration issue.
