New to HDTV.....help

Hello All. I see that the Directv H10 HD receiver has been having problems. I also read here that DTV sent a system upgrade, which I did receive yesterday here in Maryland - old 4.03, new 4.33.. Bear with me as I am new to this forum.

I have a Mitsubishi Medallion Series TV 62725 (HD) DLP. The TV can accept 480i/p, 720p and 1080i. The Directv H10 HD is connected to the receiver via the HDMI. Below are my questions.

1. I have the resolution set to "All" and Native "Off". When I turn to the DTV HD channels, I get 1080i for all HD channels and the TV does not black out when I switch the channels. Now, when I set the TV to "All" and Native "On", the TV blacks out for a few seconds before tuning to the channel, specifically channel 73 ESPNHD. Also channel 73 now displays 720p and not 1080i. What's wrong? Which set up should I keep?

2. Which HD resolution is best - 720p or 1080i?

3. I'm about to have an OTA installed Friday and wanted to know if I can just plug the coax directly to the TV's Ant input or do I have to connect to the H10. I am trying to cut out DTV $5 charge for the local channels, which over some years will pay for the Ant. Will there be any ill effects?

3. Since I got the system update yesterday (i.e. I saw this in one of those set menu selections) do I need to reset the entire system to possibly help with the black out issues.

Thanks for any help. Peace :confused:

Your first question.

Your H10 is configured correctly. ESPNHD is broadcast in 720p, that is how it is "pushed to your TV. If you use 1080i on ESPNHD then the "scrolling ticker" will not be seen.

number 2. I use "ALL" and Native "ON", this allows the H10 to push the correct resolution to whatever format it is being broadcasted in.

connect your TV ant to the H10, keep in mind you will have to return to setup and scan for your channels.

I don't think you have an "Blackout" issue, it takes a few seconds, to get the correct resolution on the channel you are watching example, Fox News channel 360 is broadacst in 480, ESPNHD, OTA ABC and Fox locals are broadcast in 720p; NBC and CBS in my town San Antonio is broadcast in 1080i.

I hope this helps.

Well Let me give this a shot here. I have mine set at native, and it does flicker black between channels because some are 720p and some are 1080i.
Now when the reciever is set to native it will switch to whatever the show or channel is being broadcast in. 480/720 or 1080. Example ESPN is 720p so now if you switch to Yes-HD its 1080i it will switch to that.
Basically on native it will switch to the accual resolution of the broadcast.

**The couple seconds of blackout you experience with native on could be the box determining what format the channel is broadcasting in. The "Native" setting means that the box will set itself to whatever format the channel you are watching is broadcasting in. ESPN HD probably broadcasts in 720p and that is why your box is setting itself to 720p when you watch that channel.

2. Which HD resolution is best - 720p or 1080i?

***1080i is the best resolution. Not all channels broadcast in 1080i though. I think CBS might, and PBS affiliates usually do. Others broadcast in 720p.

3. I'm about to have an OTA installed Friday and wanted to know if I can just plug the coax directly to the TV's Ant input or do I have to connect to the H10. I am trying to cut out DTV $5 charge for the local channels, which over some years will pay for the Ant. Will there be any ill effects?
***Unless your TV is a true HD set (meaning you dont need to run the signal thru the Direct TV set top box to decode the HD signal) you will need to run your coax thru the Direct TV box to get an HD signal. All you have to do is plug the line from the antenna into the box and the box will do the rest.

3. Since I got the system update yesterday (i.e. I saw this in one of those set menu selections) do I need to reset the entire system to possibly help with the black out issues.

***The blackout issues you are having are probably unrelated to the system update. If you switched your Native option to off and set your resolution manually you probably won't have the blackout issue anymore.

Thanks for any help. Peace :confused:

Thanks for the info. I feel a little better now. Peace

Which image format is preferrable depends on the content being viewed, and the native format of your display. Your DLP has a native format of 720p.

1080i has more pixels, but is interlaced & a framerate of only 30 fps. It is better for images with little motion, as motion creates interlacing artifacts. The slower framerate doubles the size of the motion blur compared to 720p.

720p is progressive scanned, and has a framerate of 60 fps. No interlacing artifacts & half the motion blur. IMHO, 720p/60 is superior for the content I watch... which is why I bought a 720p native DLP.

While 720p/60fps may be the better format for high motion video, there is not a choice given for the source you will watch. You have to view whatever format the channel you want to watch in the format they send it down the line to you.


Actually the type set you choose will determine the ultimate resolution and framerate you are able to view. With the STB set to feed through the signal will probably be best for you even though you get that black screen while the TV is figuring out the new format. If you are a person that surfs constantly, then you will probably want to set the STB to a fixed resolution so that the STB converts the signals to the desired format rather than allowing the TV to do it. That would be 720p for your TV.

I notice ESPNHD is 720p also. But I also have it along with everthing else set to display 1080i just to avoid the temp blackout and flicker. That is really bothersome to me since I like to surf alot. I've never noticed the ESPN lopped off at 1080i....I thought the H10 converted it with no problems. I'll have to double check to make sure.

check the scores at the bottom of the screen, espcially noticable on fox news channel 360. unless my TV is messed up.

ESPNHD doesn't lop off the scores for me at 1080i.....just re-checked. Don't know what to tell you except that maybe the aspect ratio settings on your box and on the TV are interactive. So maybe you should double-check them.

1080i will not cut any content. It doesn't specify the size of the screen, but rather the scan lines and fps displayed. setting it to 1080i will only force the stb to force a 1080i signal to the TV, which (because he has a dlp) will be down-converted to a 720P anyway.

It sounds like you may have your tv set to zoom in on the picture.

I am pretty new to directv, actually had it for about 5 months now. I am planning to move and i currently am under a one year contract with directv. The place im looking to buy is a condo which has trees all around it and looks pretty much likely i wouldnt beable to get a sattelite signal from my location. has anyone had a simular situation where they were under contract and moved somewhere they were not able to get a signal? and anyone familuar with ending there existing contract with directv and what the consequences are?

Thanks. I reset the resolution to "All" Native "On". I just thought I was having the blackout issue. I can deal with the delay it's only a couple of channels.
