Update makes TV app 480p on start up

I am sorry to hear about the issue. To get a better idea of what is at play here, the following information is very useful. I have not yet heard of the system update doing such a thing, more proof would be excellent for me to follow up on. Before I do that, let us run through the troubleshooting (if you are so inclined).

1. Make AND Model of STB (cable/sat box)

2. TV Provider

3. Layout (example: STB HDMI Xbox One HDMI TV) (please note splitters and hubs).

-Cheers

Thank you XB1R Hermes!

I have DirecTV as my satellite provider.

My DirecTV HD DVR model HR24 is connected to my XBox One via standard HDMI cables.  From the XBox One, I have an HDMI cable connected to a powered Auvio SimPlay HDMI selector which has 4 HDMI inputs.  The HDMI selector is needed to share an HDMI input on my TV with 4 devices (my XBox One, DVD Recorder, Nintendo Wii, and a Google Chromecast).  The HDMI output from my HDMI selector is connected to an LG Plasma TV Model number 50PV400.  The other HDMI input on my TV is not being used, since I don't want to buy any more expensive 10-foot long HDMI cables for it (I have my TV mounted inside a very wide entertainment center.

Please keep in mind that I had no issues at all with my setup prior to the XBox One system update.  

Just to make sure that my HDMI selector wasn't an problem, I connected my XBox One directly to my television today and bypassed the HDMI selector.  It didn't make a difference.  The picture was the same 480p resolution on start-up.

Thanks again.

I have a similar problem.  My pass through TV signal comes out as a lower smaller image (like a letter box but with black all around it like a photo frame)

It could be 480 I guess I have not measured it.  

I can stretch it to fit in the Xbox settings, but its scaled and doesnt look good (not HD quality) and if do scale it up the menus from the cable box are too big and run off the edges of the screen.

I havn't done much troubleshooting yet (I leave my cable box on all the time and I dont have the Xbox turn it on or off)

STB is a Motorola/Comcast HD DVR box

TV is an Olevia 720p LCD

STB ---> HDMI cable ---> Xbox ---->HDMI cable ---->  TV

No other connections.

It turns out that this problem is NOT new.  Others have had the same issue dating back to the November launch.  The link below proves it.

I am extremely disappointed.  The more I think about it, the more I regret buying my XBox One at launch.  It's going to take a lot of fine tuning to get the TV app to work properly for everyone, regardless of their TV model or cable or satellite provider.  What remains to be seen is whether or not Microsoft is willing to acknowledge all of their issues and work diligently to fix them.  So far, all I've seen nothing from tech support but denial.  The line I keep hearing is, "That's the first I've heard of that issue."

For what it's worth, I've spent the past couple of days trying even more fixes on my own, all to no avail.  Add these to the list:

1. Switched the DirecTV box native resolution option to OFF.

2. Unselected 1080p as an option on my DirecTV box.  720p is now the ONLY option checked.

3. Switched DirecTV box aspect ratio to 4:3 instead of 16:9.  The XBox One support website suggested that.

4. Turned OFF the XBox One's ability to turn my DirecTV box on and off, so that the DirecTV box is always ON and ready to feed a signal to the XBox One during start-up.

In short, NOTHING works.  No matter what resolution I have my TV and DirecTV box set to, the XBox One will always power on in 480p with a picture stretched all the way off the screen.  I hate it!

After further review, I have NO DOUBT that there is nothing wrong with my TV, satellite box, HDMI cables or settings.  The problem is definitely the updated XBox One TV app.  

How do I know?  I noticed that the XBox One TV app never launches in 480p whenever another app besides the TV app is in the main window at start-up.  In other words, if the YouTube app was the last app used before the XBox was shut down, the XBox will boot up with the YouTube app in the main window (not the TV app).  In that case, the XBox doesn't need to hurry up and put a live TV picture in the main window at start-up.  What I've noticed is that the TV app launches just fine (in 720p) whenever it is not pre-loaded in the main window and it is selected from one of the smaller windows underneath the main window.  That tells me the XBox One isn't giving itself enough time to load the TV app properly at start-up when it's in the main window.  Clearly, the system update was designed to make the TV app load faster than before, but I'm afraid the extra speed causes a flawed picture that is displayed in 480p.

When given enough time to load after start-up, the TV app works fine.  That also explains why cutting off the satellite box and cutting it back on again upgrades the corrupted 480p picture to 720p instantly.  It's just giving the XBox more time to load the TV app, and then re-sending the signal from the satellite box after it does.

In conclusion, The TV app needs to be updated again to fix this problem.

Thank you for the nice run down on troubleshooting. I hate to take the low-road, but upon testing simplification to form a control. Have you removed the switch to test?

Thank you for responding Hermes.

Yes, I removed the switch completely from the chain to see if the picture looked any different without it.  Unfortunately, it was the same 480p, overstretched picture.

The HDMI switcher was among the first possible causes that I tested.  I'm sorry I forgot to mention that earlier.

I have switched my XBox One power settings from "Instant ON" mode to "Energy-Saving" mode.  The TV app now launches in 720p every time, which further convinces me that "Instant ON" mode loads the TV app too fast to work properly (at least with my DirecTV receiver and TV).  I'm ready to bet my life on it.

I don't want to jinx it, but I turned my TV on twice today with no issues.  A perfectly-scaled 720p picture loaded into the main window with the XBox in "Instant ON" mode.  I haven't changed anything.  It's just working, at least for the time being.  Perhaps there was a TV app update last night?

Never mind.  It was working just fine for about 2 days, then this afternoon I turned on the TV and it was back to the same overstretched 480p picture.  The only thing I did different this afternoon was a hard reboot of my Xbox One.  I had to reboot because My XBox Live screen kept showing those pesky loading circles instead of actually loading content (even though my XBox One passed an internet connection test).  After rebooting, XBox Live loaded just fine, but the TV app was back to being broken.  I just can't win.

I know this is a ridiculous question, but could there be a connection between how the TV app loads and how XBox Live loads?

Here's an update.  After trying every possible fix for weeks now, nothing has changed.  The TV app still boots up with an overstretched 480p picture.  As I mentioned earlier, I strongly believe an update is necessary for the TV app to work properly.  Perhaps the TV app should wait a few seconds longer before attempting to display the live TV picture.  That would give it a chance to get complete signal information from the set-top box, including the correct resolution.  Why else would the TV app work perfectly whenever it is NOT in the main window on start-up?
