I'm somewhat of a novice when it comes to high-end video, so I'm coming to you guys for help. I've got two short questions with a long explanation... Here are the two short questions: 1.) How do I know what refresh rate an HDMI cable is rated? 2.) How much difference does it make? Here's the long explation to my questions: Last year we bought a new Samsung 52'' LCD TV that touted the difference its 240 mHz refresh rate would make in an HD picture. I connected it to an up-convert Sony DVD recorder using both a cheap HDMI cable and a Rocketfish (Best Buy) HDMI cable that claimed to transmit a 120 mHz refresh rate signal. With either cable, the picture was great, but I never got over a 60 mHz signal. I was told at the time that 60 mHz was the best a standard DVD upconvert could do. Then, for Christmas, I received a Sony Blu-Ray DVD player (model BDP-S360), which I connected to our 240 mHz refresh rate-capable TV with the Rocket Fish 120 mHz capable cable. Needless to say, the picture was astounding, but when I checked the refresh rate, it was only 30 mHz on a Blu-Ray DVD, but 60 when playing a standard DVD. I thought about going to Best Buy to get a Monster brand cable capable of 240 mHz, but most of the reviews say to save my money and get my cables from from someone like Blue Jeans Cable. What's a novice videophile to do?
