First, a simple question (I think) and then maybe some more complex issues...
(sorry for the length of my post, I'm only slightly informed on this stuff and wanted to provide all the details needed to orient me - please be gentle)
Is it true that a coax cable is not capable of transmitting HD programming?
The reason I ask is because that's what I was told by a support person from the manufacturer of my new TV, when asked why the image quality on this nice TV was so poor. They said that coax cable (which is how this TV is connected to its signal source) is simply not able to carry an HD signal. While that sounds plausible to me (I know nothing), I wanted to get confirmation that this is indeed true before taking any further steps, because it could be complete BS, too.
Here's more background on my setup...
We have had Dish service in the house for about 3 years* (maybe it's time for me to renegotiate - see below) . I got Dish when we replaced our old, primary TV in our living room. At the time, we dumped Comcast (a move that made me very happy), junked our old analog tube TV and got a decent flat screen Vizio TV (we'll call this TV#1). Before the switch to Dish, we had 3 TVs in the house, all analog tube TVs: one downstairs in the living room (TV#1), one upstairs in the master bedroom (TV#2), and one small one in an upstairs office (TV#3). All three TVs had existing coax cables that had been used previously for the Comcast feed. When we switched to Dish, we got one new TV for the living room (TV#1), replacing the old analog TV that was there. On installation day, Dish brought us a VIP722, which we located adjacent to the new TV#1 in the living room. I also have an external HD connected to the VIP722 via USB. The VIP722 is connected to the adjacent TV#1 via HDMI cable. The picture on TV#1 looks good, from live TV to recordings (of course, HD content looks better than SD). TV#2 upstairs in the bedroom was an older analog tube TV, which we expected to replace some day (some day came a couple weeks ago). This TV was fed by a coax cable. The picture quality on TV#2 was OK, not super, but it was what we expected on an analog TV. Recently, I decided to replace TV#2, swapping in a new Vizio E480i-B2 (48" class) TV. I hooked it up using the same coax cable that had been feeding the older TV it replaced. The picture quality is not good, viewing either live or recorded HD programs - it's a bit fuzzy, muddy and obviously not what the TV is capable of. We also have a (new) Bluray disk player connected to the new TV#2 via HDMI cable, and the picture quality from that is spectacular. When viewing any signal coming from the VIP722 (via coax cable), the TV (TV#2, new) says it's displaying 480i. When viewing a DVD or Bluray disk from the Bluray player, the TV says it's displaying 1080p.
Both TV#1 and TV#2 draw their signal from the VIP722 (programs recorded to the VIP722 hard disk are available on both TVs).
(TV#3 has not changed. That's a small, analog TV in an upstairs office that is fed by another coax, going into a VIP211K. No issues with that, low expectations there, not part of this question.)
I called Vizio product support and related the above. The Vizio CS agent said that the new TV#2 will not be able to display HD as long as it's being fed from the VIP722 via coax. Coax doesn't have HD capacity. Hmmm.
The signal from the actual satellite dish itself goes to a cable junction box (on the side of the house). That first run of cable looks like HDMI or some other high capacity cable - it's not a round cable like coax, it's flat and thick. But running *out* of the cable junction box, there are three coax cables. One goes to (I assume) the VIP722, one goes to TV#2 upstairs, and a third goes to TV#3 upstairs - at least that's my guess, I have not followed each cable all the way (cables run along the house exterior; it's night time now so I can't easily see all runs, but I'm pretty sure I have it right).
So it appears that a high-capacity cable delivers the sat feed to this junction box, and from there, all remaining cable appears to be coax - except for the short connection directly from the VIP722 to TV#1 (and the connection directly from the new Bluray player to TV#2).
This appears to be how things are wired (I hope the formatting is preserved...):
-------------------------------------------- --- TV#2 (bedroom upstairs)
------------------------------------------/
dish -- junction box ====
------------------------------------------\
-------------------------------------------- --- VIP722 + TV#1 (living rm)
All single cable coax here, except for the first run of cable from the sat dish to the junction box.
I am guessing that the signal between the junction box and the VIP722 must be bi-directional - is that possible? - since it appears to be the only connection between the VIP722 and the junction box. It must feed the incoming signal to the VIP722, then carry the output from the VIP722 back to the junction box, where it then goes up (again via coax) to TV#2 upstairs. If that's not how it's working, then I'm stumped.
OK, so that's how things appear to be wired, at least to me.
Given all the coax in the mix, I am skeptical that the information provided to me from Vizio tech support was accurate and complete.
So my questions...
- How do I ensure that I'm getting an HD-quality feed from the VIP722 up to TV#2 upstairs?
- Was the Vizio tech correct in telling me that the problem is the coax cable feeding the TV?
- If so, is the solution to run HDMI up to TV#2?
- Or is the issue really just a setting? If so, is that a Dish setting, or a setting on the TV?
- Basically, who do I call next to resolve this - Dish or Vizio?
*It has been well over 2 years since we signed up for Dish. Is now a good time to try to renegotiate our subscription - or is that a fantasy? This is a separate question, but if I have to call them and they need to come do some cable work, maybe I could kill 2 birds with one stone. Just a thought. Right now I'm mostly interested in addressing the picture quality issues on TV#2.
Thanks for your help and for any suggestions.
