Rumour has it that this plasma screen was a donation from YUSU many years ago. No one of that era remains to confirm or deny this. | Rumour has it that this plasma screen was a donation from YUSU many years ago. No one of that era remains to confirm or deny this. | ||

There is a permanent burn of the YSTV logo in this screen, as it is often left on a logo during broadcasts when on camera. There is a white-bar-scroll function to mitigate this, but it is never used. In more recent times, images of pineapples and Nicholas Cage have been burnt into it, but have not lasted long. | |||
Doesn't natively support HD-SDI or HDMI (we don't have the option cards), but using a HD-SDI to VGA converter allows it to display 1080i50 signals from the vision path. | |||

Donated by [[hist:Peter Eskdale|Peter Eskdale]], allowing the TV to be now connected over HDMI (allegedly uses HDMI 1.2). It should automatically negotiate to run at 1280x720p, it should also be possible to output 1080i50 although it is only a 768p panel. | |||

The commands are issued by placing the ASCII characters of each command between a STX (start transmission) and ETX (end transmission) ASCII control code. For example, to turn off the panel you issue <STX>POF<ETX>, or 02 50 4F 46 03 when seen in hex. | The commands are issued by placing the ASCII characters of each command between a STX (start transmission) and ETX (end transmission) ASCII control code. For example, to turn off the panel you issue <STX>POF<ETX>, or 02 50 4F 46 03 when seen in hex. Parameters that are numeric (e.g. AMT:0) are spelt out in ASCII numerals; for example AMT:0 would be spelt 02 41 4D 54 3A 30 03. | ||
The panel will respond with a similar-looking string that indicates the command was recognised. If the command isn't recognised, no reply is sent. In Panasonic projectors, it's possible to query the state of the device with commands that begin with Q - e.g. <stx>QPW<etx> will query power status, QIN/QIM will query input source, QSH queries the picture blank status and QAV queries the current volume. Some of these functions may carry over to the plasma screen, but are untested. | The panel will respond with a similar-looking string that indicates the command was recognised.

The screen now lives in the main studio on a raised wheeled platform. The screen is sometimes used as part of the set for game shows or for tea time chat. Also useful for those in front of the camera to see themselves either as the output of the stream or as the multi-view. Rumour has it that it also has been used late at night to watch back the original footage of Jim'll sodomise you. | |||
