This is a most excellent place for technology news and articles.
TVs often do a bad job at switching on when the computer turns on, then off when it turns off/goes to sleep. Drives me spare. That was fixed in like 1995-2000 for normal monitors.
CEC has been around for years. This is probably more an issue with the PC in question rather than the TV. TVs do an excellent job at turning themselves on when CEC is enabled. ๐
