HD Picture on HD Channels after splitting the signal?

should still be HD as long as the splitter has not reduced the signal below it's "lock on" levels I work for a cable company.. your Transmit, Receive, and Carrier to Noise ration must be within certain levels...or you will have problems ...to receive HD channels you will need a digital converter box (Set Top Box)

Depends how good of a job you did and if it is cable, Directv, etc. If it is Directv, I have a high confidence both TVs will not work. If you are lucky, one of them will still work. If it is cable and you did a good job and if some of the channels don't require a cable box, then you might get lucky and both TV could work.

Umm... to the cable guy :) ... just one quibble: > to receive HD channels you will need a digital converter box (Set Top Box) There is an exception - cable companies are required to carry the local OTA DTV channels, "in clear" (unencrypted). A TV with a QAM tuner will be able to receive them without a cable box. Similarly if there are any other unencrypted DTV channels on the cable, the TV with the QAM tuner can receive them. Of course most systems don't have any such channels. But they're required by the FCC to carry the local broadcast stations "in clear" and this has been interpreted to include the digital broadcast signals (since, of course, soon that is all there will be). This is not meant to detract from the rest of your answer, which of course is accurate. The questioner should give you 'best answer'. :) btw, my personal experience agrees. My cable comes into my place, first gets split off to a cable modem and to an analog VCR, then gets split again in the bedroom to feed the bedroom TV, and finally manages to get downstairs to the living room where the digital cable box. The HD works fine in the living room. The bedroom TV can see the clear QAM channels on the cable, too, but I hardly ever watch them since there's no DVR in that path.
