Nope, verified working. If it supports 12bit then it will support 10bit. High color displays are backwards compatible with lower color outputs. Dell at work will do 6/8/10/12bit with no issues. Can't really compare a TV to a desktop monitor. A TV that doesn't implement a specific color output into it's programming doesn't mean it doesn't support it at hardware level. Some TVs wont even accept RGB output from PCs but RGB works on other devices.
