Proposed HD-SDI upgrade board for XCS TB-6 CRT monitor
14 years old. Gear and prices may have changed since.
DisputedParticipants disagreed and reached no conclusion. Read the findings as positions, not as an answer.
What the thread found
- An upgrade board was being developed to add HD-SDI input compatibility to the TB-6 monitor while maintaining its analog display output to the CRT tube.
- The upgrade would provide higher resolution analog video than standard NTSC downconversion, with support for HD-SDI framelines.
- Existing TB-6 monitors were intended to be upgradeable with the new board.
- The TB-6 would retain its original 8-pin Lemo connector for NTSC analog input after the upgrade.
- CRT tubes suitable for reference video display require analog driver signals; digital signals must be converted to analog to drive the tube's flyback coil.
Depends on
- Project status and actual availability were unclear at the time of discussion; no confirmation exists that the upgrade was completed or brought to market.
- The market for CRT monitor upgrades was very limited due to the scarcity of quality replacement tubes.
- Resolution specifications of the upgraded analog driver were never confirmed in the discussion.
- This was a 2012 discussion; the technology may have been abandoned due to lack of commercial viability.
