HDMI cable questions

OK, we just bought a nice new Ultra High Def 4K TV. Next week, we'll be having Comcast internet installed, which is 105MBps speed, if I remember correctly. Now, if I want to watch 4K programming from Netflix (or elsewhere), what sort of difference does the HDMI cable make? I see cable rated for 10.2GBps, 18GBps, 22.5GBps, 29GBps, etc... I had read somewhere that if you want to stream 4k programming, you need internet speeds of 25MBps, which if well under even the lower rated speeds of the 4K HDMI cables.

So, am I okay with just a regular 4K HDMI cable rated for 5 or 10 GBps? Or, would getting 22 or 29 GBps make a difference?

4K Support

The HDMI 1.4 specification adds support for extremely high video resolutions that go far beyond today’s 1080p systems. 4K is shorthand for 4,000 lines wide by 2,000 lines high, or roughly four times the resolution of a 1080p display. The term actually covers two formats, both supported in the HDMI 1.4 specification:

3840 pixels wide by 2160 pixels high
4096 pixels wide by 2160 pixels high

4K displays will put high-end home theater systems roughly on a par with the state-of-the-art Digital Cinema projectors used in many commercial movie theaters. Staying true to its commitment to future-readiness, the HDMI standard can now support these systems with the extremely high bandwidth connectivity they will require.

How to Ensure 4K functionality in your Home Theater System

Look for devices that support 4K functionality.
All High Speed HDMI cables will support 4K functionality when connected to 4K devices. You can use your existing High Speed HDMI cables or choose a different cable type.

As long as it meets the HDMI 1.4 specs, I would say you are good. Unless you are going to need the added Ethernet usage.
