HD resolution setup question

08-08-2005, 10:05 AM
so i went into my hdtv setup menu and changed it to 1080i as soon as i did this the screen went black like i still have sound on all my channels but just a black screen. My tv says 1080i on it so i dont see what happened. I tried resetting it and that didnt work. Any help would be greatly appreciated. :confused:

Your HDTV's setup menu? The resolution produced by the TV cannot be changed. Do you prehaps mean your external STB's setup? What makes & models of hardware are you using, and what type of interconnects?

Sorry i wasnt specific enough I went under my dish network menu. Menu button then pressed 6, 1, 9 then i switched it from 480p to 1080i. After that I pressed save should I have selected adjust first? cause as soon as i saved it the screen went black. :(

Are you using HDMI cable or component, or perhaps attempting to use both?

I think there are some stipulations depending on which cable you are using.

Over at Satellite guys they call that the black screen of death. Mine would black screen and have to be physically reset to get any video back when switching to or from any of the resolutions. Mine would always go black going from 1080i to 720p.

I have a question reguarding resolution also. If say tnt hd is broadcasting NASCAR in 1080I and ESPN hd is broadcasting in 720P, do you need to adjust your receiver to the according resolution for best picture? I always have my 811 set to 1080I. Thanks

Depends on your setup... you don't NEED to change anything, the tuner will convert whatever is received to the configured output res. If your TV has a better format converter than your STB, you may want to use 'pass thru mode' which outputs whatever res is received... that's essentially what you're doing by changing to the broadcast res.

Bottom line, whatever res is received is ultimately converted to the native res of your HDTV, since TVs are MONOsync not MULTIsync devices.

I use an HP multimedia projector fed by a Dish 811. I have to manually set the resolution as necessary on the 811 to tweak the picture quality. I have never experienced any of the black screen anomoly.

Was wondering if the problem might be in the input being used. I have a similar problem with a Philips TV when using the component line input 2. It appears to only work with 480p (i.e., screen blanks as you indicated) while component line input 4 automatically switches between 480p and 1080i as output by the receiver. Have to admit, however, that I prefer the 480p setting as there is less overscan as displayed on my particular TV. (Unfortunately, TV is older model without HDMI, so I couldn't check that aspect.)
