What would it take to make a 120hz *input* TV

[psolord]

snuuggles, congratulations on your queries in this thread (and your patience) and thanks for the bump, otherwise I would have missed it.

I've been using a Philips 32'' PFL9603D for three and a half years now, as a computer monitor and I am loving it. Some people may consider 1080P to have a very low ppi for 32'', but I'm fine with it.

That being said, after watching Avatar back in the day, all I could thing of while watching the movie, is wow, think about the possibilities in gaming.

And bam, here we are today, with only a handful of 1080P/120Hz solutions that can do 60Hz per eye stereoscopic 3D. So as per the topic of this thread, 120Hz native input is very crucial, for both 2D/120Hz and 3D/60Hz.

I've been monitor the situation for a long time now. Come the new Nvidia 7XX series, if a HDTV with native 120hz is not available, I will just go for the Asus VG278H and call it a day. This will be a severe downgrade though, since I was aiming for a 37'' this time.

The infernal 300Mhz HDMI chips have been made available since May 2011 for the love of God.

Makes sense they are coming from SI since they were very actively involved in the TMDS signal development.

And of course apart from HDMI, they could do it with other ports. I don't know why no manufacturer has taken interest in this. Ok it's not like it's a huge market, but it's a market non the less.

LCDs don't have a refresh rate. They're not CRTs. So 60mhz and 120mhz will look the same if you watch tv. To work out a LCDs real emulated refresh rate
1000/response time

You're wrong, they do have refresh rates.

And actually they do refresh in a very similar manner to CRTs, you're right when you say they do not use an electron gun, however they do scan down the screen line by line when they refresh.

The fact that LCDs can (and do) have tearing is proof of this.

The response rate is something entirely different, that is simply the time it takes for a pixel to actually change from one colour to another. You're confusing latency of an operation with the frequency of that operation.
