SageTV 120Hz???

[vexhold]

I currently have a 52" Samsung ToC 650

It is a 120Hz LCD but I have yet to get it to utilize it using SageTV.

I thought it was because I was going directly from the Server when watching movies, but now I have it fed from an HD200 and still the same thing.

Does anyone have the same TV that could shed some light on this issue?

I have tried AUTO and HIGH for the 120Hz Settings, but it changes nothing.

Whats the problem you are seeing?

You say it changes nothing, what are you trying to change?

Make sure you cycle thru the resolutions with the video out button on the remote and give it time to sync after each push. (Maybe up to a minute)

On the TV, if you hit INFO, it tells you the time, date, input, resolution and Hz of the current display..

It never changes from 60Hz to 120Hz.

Make sure you cycle thru the resolutions with the video out button on the remote and give it time to sync after each push. (Maybe up to a minute)

Thanks, I will try that tonight.

I just got a new LN52A850 last week (the PQ is amazing).

I'm pretty sure these sets only accept up to 60Hz input and interpolate frames for the 120Hz refresh when Auto Motion Plus (AMP) is enabled. I leave it set to low. Any more and it gives too much of that soap opera look.

Aloha,

120 Hz TV's do not accept a 120 Hz input signal. They accept a 24 Hz, 30 Hz, or a 60 Hz signal and internally multiply it by 5, 4, or 2 to get 120 Hz.

This is too bad because I was hoping to be able to set my PC to 120 HZ refresh for better gaming but alas...

Yea, this is a misconception about 120Hz TV's. AFAIK they never accept a 120Hz input. As was said, the reason for a 120Hz TV is because it's the lowest common denominator for 24, 30 and 60. Remember algebra? For this reason you don't need a 120Hz input to take advantage of it. That might actually make things worse. What it does do is allow film or video at 24, 30 or 60fps to all be displayed smoothy without judder because there is no need for a 3:2 conversion.

True. Today adverticements with 120Hz and 240Hz LCD's are just confusing customers. Making them look for compatible devices for content delivery. When in fact, HDMI (as of today) has 1080p 60fps as highest possible video signal (as far as I know).

Nothing to be sad about really. Because the 120Hz and 240Hz functionality are good stuff. It does make material with much movement, like sports, shine in HD.

The future may bring 120Hz over HDMI though. One reason could be 3D:
HDMI spec could see update to better handle stereoscopic 3D

Also on the computer front there are/will be LCD's with 120Hz real refresh rate. But here we have HDMI / DVI / DisplayPort / ... Not sure who will prevail here. Something needs to change though, because having to connect two DVI cables against display. To go beyond the 1920x1200 resolution, is not very elegant.

Dual-link DVI is only one cable, just with more pins. I have a Dell 30" running at 2560x1600 res and it uses one DVI cable that just has a bunch more pins. No big deal, other than you darn well better use the cable that came with the monitor.

Thanks. Learn something new each day Haven't read the spec good enough. Bought 24" a while back myself, so only needed 1920x1200. When I bought it I though the first 30" was two 'separate' displays. Might be wrong though. From the wiki on DVI I now see that you can get 2560x1600@60Hz or 3840×2400@33Hz through DVI-D Dual Link. Or 3840×2400@17Hz through DVI-D Single Link. The last one must be a fun mode to work with
