Should I believe this email (related to 120hz tvs)

Dear Ayashi Kaibutsu,

Thank you for contacting Samsung Electronics.

We understand that you want to know if there are any TV's that support 120Hz.

The following model TV's support the 120Hz input devices: UN40D5003BF, UN40D5005BF, UN40D5500RF, and UN40D5550RF.

It says 120Hz input devices. I can't find accepted inputs in the documentation for those. The only company that even bothers to specify it seems to be Sony and they apparently don't have any.

Edit: I tried Live chat to verify and explained multiple times that I was looking for 120Hz input and not 60hz + 60 that the TV made up, and they insisted it's supported.

If it's not explicitly in the specs it's not supported.

HDMI 1.4 supports 4096x2160@24Hz

That's 1080p at 103 Hz. 120Hz 1080p can't happen over HDMI. Period.

For it to support 120Hz input it must have Display Port or dual link DVI... which of course it won't have, as big media has mandated HDMI for copy protection reasons... TVs that call themselves 120Hz are ALLLLLL fake 120Hz.

Yea, I was figuring as much, but I get hopeful easily : (
 
HDMI 1.4 has a maximum clock rate of 340Mhz. That is 142.886Hz for most generic 1920x1080 (2080x1144) LCD monitors.

My BenQ XL2420T really only needs 7 blanking lines (2080x1087) to display a nearly perfect picture reliably. That is a pixel clock of only 271Mhz for 120Hz. You could probably get it a lot lower by messing with the horizontal blanking space. Unfortunately it can be a bit of a crap shoot. I wish my camera on my phone worked, I know of a few settings that are worth a few giggles.
*edit*
BTW No, Those monitors don't support a 120Hz input 🙁
