I'm trying to get to the reality of inputting at >60 Hz over HDMI. I know that most LCDs on the market can't handle this... but I just think Panasonic TH-42PZ80U plasma might be capable of handling something over 60 Hz.
The specs on my plasma state an internal refresh rate of 480 Hz. This means that any number of even multipliers could be used for various refresh rates without rendering judder. e.g. 80 Hz, 120 Hz, 160 Hz. Obviously 80 Hz wouldn't be useful for video content, but for games it would be great.
Now, I'd be prepared that the internal refresh rate is strictly that... but when I probed the display configuration options, and the display was reporting it could handle up to a 330 MHz pixel clock. That's high enough to drive the display at 1080p 120 Hz easily.
However, I've not been able to get any settings above 60 Hz to work, but there's a pretty innumerable number of low-level configuration options. Anybody have ideas on what might work? Or confirmation as to why >60 Hz isn't going to work?
