using the charts here (http://en.wikipedia.org/wiki/High-Definition_Multimedia_Interface#Relationship_with_personal_computers) what ver would offer the optimum performance on my ln40a650?
I just bought a LN40A650 and one of the driving factors was the 120hz refresh rate. I have a scientific atlanta 8240hdc and am using a standard hdmi to connect w/my tv.
I am trying to figure out why the picture keeps coming up as 60hz when i hit info on the samsung remote. Is this bc i need a ver 1.3 hdmi cable? As i see some hdmi's are advertised as supporting 120hz?
Which version does the ln40a650 take?
and if i am connecting my macbook does it make a difference?
Then I read in a product description of the LN40A650 that "...4 HDMI v1.3 (3 rear, 1 side) ? accepts signals up to 1080p (60Hz, 24Hz)" (http://www.crutchfield.com/S-mZYLUEmZQY0/p_305LN40650/Samsung-LN40A650.html) which seems to say no matter which hdmi I use it will only support 60hz(?).
So I am trying to figure out what input must i use to get a 120hz refresh rate?
and does it make a difference what type of coax is used between the outlet and the box? could that be the issue?
Please help as i know so little about this stuff i may as well drive to amish town to get some answers.
