X Series quick input and output checks
Overview
These checks cover the fast fixes surfaced in the source FAQs for X3 and X7 class issues.
Applies to
X3, X7
X3 input resolution reads incorrectly in XPOSE
- If a PC is sending VGA and XPOSE continues to report 1920x1080@60 while the source resolution changes, review the PC display-scaling setting first.
- In the source guidance, maintaining display scaling on the PC side was the recommended correction.
X7 common quick checks
- If an SDI board shows no input, hot-plug the SDI path and try a different slot.
- If there is no output, test a different output format before assuming board failure.
- If output flashes briefly and then disappears, factory reset the unit and re-seat the output board.
- If 4K input is not recognized, re-seat the 4K input board and allow roughly 45 seconds before judging the result.
Use this article as triage, not final diagnosis
- These actions are intended to isolate board, slot, and format problems quickly.
- If the same symptom survives slot changes, format changes, and a clean reseat, capture the exact board model and firmware state before escalating.
