TV & Home Theater

I recently purchased a 4K tv and want to ensure I get the best picture, period.

I am thinking about getting the Hopper 3 and Joey 4Ks.

I have standard HDMI cables that run from my Hopper to my Yamaha RX-V377 surround sound receiver and then from the receuver up to the TV.

Are standard coaxial cables throughout my house that carry the signal from the dish to the Hopper sufficient for 4K picture?

Are standard HDMI cables sufficient for 4K picture?

Is my receiver carrying the 4K signal without and quality loss?

Any other gaps that will cause me to miss optimal picture?

I don't have an opinion on the Hopper or Joey as I have cable.

However regarding your coax.

Look at a segment of your existing cable and it should have written on it what it is.

When I upgraded to HD years ago I had to have cable all the way from the street to my TV replaced as what I had could not handle it.

Chances are if your exisiting coaxial cable is more than 10 years old you may need to replace it to get 4K.

I only replaced my cable to the one HD TV in my house and to my cable modem.

Any idea what kind of writing/wording will be on the coaxial cable if it's ready and what will be written on it if it's not?

many cables will have a number like RG-##  that number will be something like a 6 or 7 and sometimes followed by a letter like U, X, A, etc...

a common cable is RG-6.  there are many dozens of possibilities.  

When your service person comes to do the install they should be able to run a test on your cable to tell you how good it is.  My cable company hooked up a device was able to get a readout of how good the signal was.

There are a variety of variables that will also have an effect on video quality.  the number of splits in the line is a significant factor.

You would want to set it up with the minimal number of splits between the dish and your primary TV.

This is the exact cable I have throughout my house

Will it work for 4K...? Fingers crossed*

Hey 4Kboy, 

Thank you for your patience as I look into your cable for you. 

While I was researching what is the best cable out there to have, you do currently have a top of the line cable. You have one that would be classified as a RG6 cable. 

There would be a RG11, and  it would be able to provide you a higher frequency and a better response for a cleaner picture. The downside to this cable is that no TV or Cable boxes will have that option to accept it; meaning that a converter would need to be used. (Converters degrade signals)

So in short, you are doing everything correct! I hope you are able to get that crazy amazing picture you're seeking! 

Please let us know if you have any other questions. 

Warm Regards, 

Mariah

Sorry I did not get back.  Looks like Maria covered it.

RG6 would be good for 720 or 1080 resolution.

4k is up to 8 times the bandwidth of 1080

RG6 carries about 1 GBPS

Some sources say for HDMI you will want to look to V1.4 HDMI or better as it is rated to carry the band width.  Others say that is bunk. Don't know have not tried it.  However, I tend to believe the technology.  One thing to consider is price on them. It should be that brand A rated the Same as brand be should perform exactly the same despite the price difference. 

You may want to directly call the people at the Dish company.
