Can you achieve a HD signal using solely the comcast cable to the HDTV and no box or DVR?

I dont deem so....you need a HD Box it will be going on for $7/month. I have the HD chanals and they are sooooooo worth it...
Yes, if your TV has a QAM/ATSC tuner. But you will single get the locals approaching cbs, abc, pbs, fox, nbc. No discovery/hbo hd (even if you already have hbo), etc unless you get the box.
Just do a channel hunt and it should find all the channel hd or sd. For me, NBC (new york channel 4) is 4-1. 4 is sd, 4-1 is hd, 4-2 is approaching nbc weather scan, etc. Hi Missing,
It can be done with a TV that accept a cable card. Unfortunately that system for some reason wasn't completely well standard and the TV selection beside cable card capability is small.
My TiVo uses cable cards so I don't hold to use a set top box.

You can't recieve any HD channel just using a cable. If you're TV is HD equipped you can use an antenna to get local stations. A standard coaxial cable isn't ample to recieve HD. Otherwise you will need some sort of subscription to your cable company, and they will distribute you an HD receiver.
HD runs on weird channel that have dash after them. Comcast configures their digital cables to run on channel that are independent of the cable box representation of them. On my dad's TV, without a cable box, TNT comes contained by on channel 74-65521, among sixteen other unsystematic numberings.
The HD box I rent from comcast costs me $6 a month. I highly suggest it if you really want HD.
But unsurprisingly if all you want is the local HD, it's configured pretty simply. Our NBC runs on vessel 7, and 7-1 is it in HD, 7-2 is weather scan, 7-3 is digital SD.
