hi! so we have this SONY Bravia TV at home. it is a 40 inches full hd with 120hz refresh rate. it has 2 HDMI ports. so my question is if I connect my gtx 960 using HDMI can I maximize the refresh rate by setting 1920x1080 @ 120hz? or my card will only read 60hz? thanks!

i'm confused with the specs about video signal here it is:

1080 / 24P (HDMI™ ONLY)
YES
480 / 60I
YES
480 / 60P
YES
576 / 50I
YES
576 / 50P
YES
720 / 24P (HDMI™ ONLY)
YES
720 / 30P (HDMI™ ONLY)
YES
720 / 50P
YES
720/60P
YES
1080 / 60I
YES
1080 / 50I
YES
1080 / 30P (HDMI™ ONLY)
YES
1080 / 60P (HDMI™ / COMPONENT)
YES
1080 / 50P (HDMI™ / COMPONENT)
YES
 
Hi,
The 120Hz is an INTERNAL smoothing option which takes a 60Hz input and creates one artificial frame for every real one.

*It should NOT be utilized because it adds a lot of additional latency when creating the new frames (suitable for sports videos, not games). It's also not suitable for movies for a different reason (the video motion blur is optimized for the 24Hz film rate).

Other:
In addition, see if there is a "GAME" mode option in the HDTV settings. This minimizes any video processing in the HDTV to reduce input latency.

UPDATE:
The HDTV may or may not be 3D, and may or may not have motion smoothing (may have 3D, smoothing, or both). Regardless, the computer does not "see" the HDTV as anything but a 60Hz screen, and anything done after that is internal.

That doesn't change the fact you should simply use the appropriate setting in the NVidia Control Panel:
HDTV-> 1080p_NTSC@60Hz

(should look something like the above, adjust overscan if needed)
 
photonboy, if the native refresh rate is 120 Hz, the interpolation is 240 Hz or more. If the native refresh rate is 240 Hz, the interpolation is 480 Hz. A few of older Active 3D sets were native 240 Hz giving 120 Hz to each eye, removing the ghosting found on 120 Hz sets, because that was the only way Active would beat Passive 3D at the time. Even if the input maxes at 60 Hz, it'll frame repeat, interpolation can be turned off.
 


HDTV's have a 60Hz input.

They display at 60Hz unless doing something like motion smoothing, or active shutter 3D. It's pointless to delve into whether he have 3D or not and if so if it's passive or active because nothing changes the fact he should be using the 60Hz 1080p setting.

He doesn't want to add smoothing due to the added input latency, nor is it suitable for computer 3D.

Other: I have no idea where you got your "480Hz interpolation" info either. Pretty sure that's wrong. If the HDTV is at 240Hz it's because it's creating THREE artificial frames for every real one (ideal for sports like tracking the football). Regardless that the content may be 30Hz (i.e. 30FPS) video input the input signal is still 60Hz, then that is turned into 240Hz by sampling several frames to determine content acceleration and then artificially creating three new frames.
 
No, my point is that if you turn off frame interpolation, you can still have the TV run at 120 Hz even if the input maxes at 60 Hz, giving you less ghosting than running it at 60 Hz. It'll simply repeat frames on it's own, which is why it's also a good idea to run a PC monitor at 120 Hz even if you only push 60 FPS, because you'll still benefit from the faster pixel times. There are a ton of misinformation floating around regarding TV's and refresh rate.
 


I see.
I know what you are getting at because I've been to the Blurbusters website.

I have no way to verify that but can't dispute it might work. Essentially it's creating black video gaps which temporarily reduce light to the eyes which end up reducing the blur caused by oversaturation in the eye/brain and it's been done in the theater for years (each image is pulsed several times).
 
It also appears there are ways to get true 120Hz from some HDTV's with a workaround:
http://www.blurbusters.com/overclock/120hz-pc-to-tv/

If you could get that working you'd essentially have a 120Hz (or almost, depending on what works) monitor.

That does present the issue when trying to use VSYNC (to avoid screen tear) is to force on the "Half Adaptive VSync" method in the NVidia Control Panel for the game as you're now trying to achieve 120FPS. Possibly make the "HALF" method the GLOBAL method for gaming and force the normal method (i.e. 120FPS VSYNC) on a per-game basis instead.

The "Half Adaptive" method simply drops to half (i.e. 60FPS instead of 120FPS) and toggles VSYNC ON or OFF depending on whether your GPU can output 60FPS or not. Thus, if it can it's just like normal VSYNC, but if it can't it's VSYNC OFF.

You never want to use VSYNC but drop below the required FPS output because that causes stutter (i.e. 60Hz, but can't output at least 60FPS).

Anyway, some food for thought.

Start with the normal 60Hz 1080p input then work from there.
 


Hi! The TV has GAME MODE in SCENE SELECT. so if I select that and go gaming that will not cause any stutter or tearing even if the FPS go over 60? i'm not an expert when it comes to FPS and Refresh rate talks all I know is when your game reaches 60 and above and your monitor only has 60HZ it will cause tearing. (PLEASE CORRECT ME IF I'M WRONG I WOULD LOVE TO LEARN). about Motion Flow . the TV,as stated in their website, has that feature BUT is always active. the only setting is CINEMA DRIVE.to be exact it is written MOTION FLOW XR 120hz
