Screen resolution file not parsed
What it means
No functional impact — this is the tool admitting it can't read this particular file, rather than silently pretending everything checked out fine.
Why it happens
This file predates the '# V2' marker introduced by B2S Backglass Server 2.0.0, or was hand-edited into a shape the parser doesn't recognize.
How Pincab Toolbox detects it
The file exists and was readable, but no '# V2' marker or recognizable layout was found in it.
