Read the desccription for 1.4a at this link
Remember that the naming convention has been changed as can be read here in this link
It might seem confusing at first but just remember that you need to look only at cables labelled High Speed as per the explanation in the link above.
I have NEVER bought HDMI cables from anywhere except MonoPrice as they have the best prices.
Here is the link
for their HDMI cable page.
The main thing you need to determine is the minimum length you need to get the job done.
Then make a shortlist of High Speed cables on that page that are available in the next highest length than you need.
If you still have multiple selections in your short list, remember that a longer cable run is better implemented with cables with thicker shielding and the thicker the shielding, the smaller the AWG number.
Also, having Ferrite Cores on the ends is a good thing but it might not be available so dont fret too much about this.
Once you have selected the High Speed cable in the length and thickness you want, you can look at HDMI port savers at this link
These are useful if you are planning to switch cables at either end as it prevents the HDMI connection at the device end from becoming really loose.
