Six identical tellies (for an identically cheap price of £420-ish) bought in August 2012, which are in fact not identical.
These monitors are fairly generic high-definition TVs built by Vestel, which then get rebadged by several different manufacturers. Each monitor is slightly different - some have red status LEDs while others have white; five have an internal power supply while one has an external 12V supply; they all have different picture when setup exactly the same.
Despite their faults, they are one of YSTV's main control room monitors. Five remain in service, with the sixth having been dropped a few times; damaging the LCD panel.
They are currently in the process of being converted to YSTV's XLR-4 power standards, with SDI to HDMI converters also being retrofitted internally.
