Situation -
I recently bought a Samsung Smart TV and wished to duplicate my display (clone) from my main monitor and stream what I am doing on it. For example the show "Band of Brothers", I ended up trying to steam it from my PC via cloned displays and this is what happened.

Problem -
The show would screen tear and stutter just enough to make it irritating on the Samsung Smart TV, yet viewing it at the same time on my main monitor it was completely fine.

Screen Tear / Stutter:

The show is going through a 20ft hdmi cable (BJC made and I am familiar with not going over 25ft) and then through a 6" inch mini-hdmi to hdmi adapter cable (I have ordered a different one with good reviews from Amazon in-case this is the problem).

4 different HDMI cables have been used to test if it was a bad cable, all get the same result.

If I take the same show and put it on a USB HD and plug it directly into the smart TV, I have no screen tearing or stutter.

Potential Diagnosis -
1.) Bad - HDMI Ports (all 4 of them)
2.) Bad - HDMI Cables (all 4 of them)
3.) Bad - Mini-HDMI Adapter
4.) Bad - Graphics Card Mini-HDMI Port
5.) Bad - Computer Settings
6.) Bad - TV Settings

Tech Specs - (links provide more specification info)
TV - Samsung UN55F8000 60HZ Native (I think)
Monitor - Acer HN274 120HZ Native
Processor - Intel Core i5-2500K Sandy Bridge Quad-Core 3.3GHz Not sure if this has anything to do with it
Graphics Card - EVGA SuperClocked 015-P3-1582-AR GeForce GTX 580 This is where the mini-hdmi adapter is plugged into


Solution - ???
I will post the solution here upon someone in this thread coming up with something. So can you guys help me out? How likely is it the little adapter is the problem?

is it when playing games or is it all the time

if it is when playing games try turning on V syne in game or you can go to NVIDA control panel and set V syne on all the time

see if that fixes it

The solution was that I was forcing the CLONED displays to use 120hz, the TV was not capable of that so it would attempt to do things it could not do. I've only updated this in-case someone stumbles across this problem.
