the connection from cable box to TV is through HDMI cable. i am not sure where the problem is exactly, but some HD channels look "better" (clean lines and edges) than other channels. there could potentially be many reasons for poor HD reception here, so i can't say for sure that the SA 8300HDC is the cause, but its just the easiest target when trouble shooting these image issues.
thanks for the tip about switching from 1080i to 720p. i was having issues with displayed letters and fonts having blurry and distorted edges, and it was quite distracting and annoying. i was power cycling the box to try and improve the image and this would work for a little while. however, setting the box to 720p now seems to have improved this issue. my HD picture quality could still be much better. for the time being, i am just going to settle on what i have, and hope the next "updates" will improve my Xfinity Xperience. i exchanged an SA 8300HDC for the Cisco RGN200N but it wasn't working at all, and the tech just gave me another SA 8300HDC, so i guess i am stuck with this ancient box for now. its a real shame to have a nice HDTV that is limited by such an inferior converter box.
..the manual refers to the ability to display different settings on the front display panel (1080i, 480i, 720p).
I am trying to figure how to change the front panel to display "720p".
I have 1080p x 720p flat screen connected with HDMI cable.
Using the silver cable remote with TV turned on, shut OFF the cable box. Then push the Zoom button [bottom right] and run the setup to get it working the way you need. Try both tests if you don't get it with the simple setup.
This allows you to select the output scanning rate of the set-top box needed for your TV.
To add, the de-interlacing capabilities of the Moto DCX3501 are quite good and generally better than many HDTV's. You can input native 1080i to the set from the DVR, but it's not as optimal taking native 720p and interlacing it and then de-interlacing again. You're better off upconverting and deinterlacing in the box before the TV.
I merged this with your other thread, since they're related. Your TV is capable of converting whatever the cable box outputs and displaying at various resolutions. The setting on the box won't cause problems such as what you describe, but if you state what make/model cable box you have we can tell you how to change the
(I see that you mentioned the cable box model in one of your many previous posts. Someone with familiarity with that model should respond soon.)
Do I need to configure the (Cisco) RNG 200 to take advange of the TV "720p" ?
It's my understanding (which may be wrong) that the default is setting for the box is 1080i x 480p.
(I am trying to troubleshoot a problem: Right now my TV blinks or drops the sound & video signal every :10 seconds or so. I am trying to determine if it is the TV or the current setting on the box. I am connected with HDMI cables).
