Does anyone know what the “Zoom” option does under “Video Display” settings in the Xi6 menu? Seems like toggling it between “Full” and “None” doesn’t do anything at all…
This setting only affects SD channels with a 4:3 aspect radio. When set to "None", you will see a square picture with sidebars on a widescreen TV. When set to "Zoom", the picture will get stretched horizontally to fill the screen.
Ahhh ok. So only SD channels and not SD content on HD channels, correct?
Yes, that's correct. The Ignite set-top box can only Zoom (stretch) a channel that broadcasts with a 4:3 aspect ratio.... and the channel needs to be encoded in a very specific way to allow that to happen.
Because all SD content on HD channels (e.g. Star Trek Voyager on CTV Sci-if) show the black bars on the sides regardless if Zoom is set to Full or None.
Yes, because while source content may be 4:3, the channel itself is widescreen HD.
Anyone else notice this improvement recently?
Yes, I noticed this as well!
It's funny... usually, I try not to fixate on that old little glitch but did when I noticed channel changes taking a fraction of a second longer than they used to, but then saw that they were now streaming immediately at a normal bitrate. The slower channel change issue (thankfully) went away and I think that channel changes on Ignite are now actually slightly faster than they were before.
