Can the Xfinity X1 box actually be set to output in 1080i instead of 720p?
I have just recently upgraded to the Xfinity X1 box. My TV is a 2003-vintage 42”Sony Plasma KE-42TS2U, capable of displaying HD in both 720p & 1080i (e.g. it displays just fine in 1080i from my Oppo BDP-83 Blu-Ray player). When I first set up the X1, it came up in 720p. My problem is that I’ve been unsuccessful in my attempts to set up the X1 to output in 1080i instead of 720p – even though the X1 has a 1080i menu setting and, as I said, my Sony Plasma displays fine in 1080i when fed a 1080i signal.
Whenever I go through the X1’s menu process to select 1080i (menu/settings/device settings/video display/video output resolution/16:9, 1080i HD/OK/Do you want to keep this resolution/Yes), the X1 seems to accept the “Yes” – but when I then check the X1’s output resolution, it still says “16:9, 720p HD”.
(Note, might this be in any way related to the problem… my Plasma set has only one HD digital input - a DVI, as it is a bit too old to have HDMI. As I have three HD digital output devices - X1 cable, Oppo Blu-Ray Player, Xbox 360 - but only one HD digital input, for years I’ve successfully used “HDMI to DVI” adapter cables, one from each HD output device, plugged into an active DVI switch box for video switching – and one pair of stereo RCA audio output cables from each device’s analog RCA stereo audio outputs, plugged into a simple stereo RCA cable switch box for the audio switching. This setup has worked just fine for my needs. However, might it in any way be related to my problem getting the X1 to output in 1080i instead of in 720p? Frankly, I wouldn’t think so, but who knows…)
Thanks, in advance.
