Resolution Gone Bad

This is a real brain twister (for me, anyway). My entertainment center consists in part, 80 in. Sharp HDTV, Denon Receiver, DirecTV box, ROKU 4, Apple TV.

Everything has been set at 1080p for a while now and working flawlessly until recently when I went into the ROKU 4 and discovered the screen width much too wide. I verified the ROKU setup was correct at 1080p but nothing changed. I then selected 720p and the width came into where it ws supposed to be which is just the opposite of what it should be. I've entered a ticket with ROKU but so far they've been unable to come up with anything.

I've verified my TV is set at 1080p as well as the DirecTV box which I realize wouldn'y have anything to do with it.

Now, stranger yet, I went into my Apple TV and discovered a screen width way too wide, At first I thought maybe the ROKU had failed but now I don't think so but have no idea where to look next.

HELP!

Is it the mode of the TV, besides just setting the resolution, isn't there TV menu option choices that let you choose which viewing mode you are using like wide 16x9 or 4x3, or cinematic

Since you didn't give the exact model TV, I just Googled 80" Sharp TV, and chose this model:
LC-80UQ17U
In the manual, it's talks more about what I was saying so maybe one of these choices works best?

That's one of the puzzling things about this TV. You can't find anywhere where it actually allows you to set resolution. There's a button on the remote that flashes a box in the corner 1080p but that's it. It must set it automatically. I've messed with all the settings under the A/V Mode and View Mode buttons on the remote but nothing seems to change the extended width or screen size of the ROKU or Apple TV.

The model I have is Sharp LC-80LE632U

What about on the remote, see the attached pic for possible location on the remote( not sure if your remote looks the same as the one in the screenshot).

Found the manual download link from Sharp:
https://www.sharpusa.com/Support/ProductDetail.aspx?model=LC-80LE632U

Here's the same page from the manual for your TV:

Actually, rereading your question. Since it was working at one time...try bleeding the entire system.

Unplug everything from electrical power, then while each component is unplugged, try turning it on if it even has an on/off switch to make sure that everything bleeds out any residual power.

Then after you have bled out everything( unplug each component from the other if necessary) plug it all back together one at a time to see if the problem is still there.

I took my ROKU over to my Daughters house to see if the results were the same as in my house and it clearly showed my problem was the TV, not the ROKU device. After spending more time focused on my Sharp, I discovered the aspect ratio had changed - on it's own, apparently. A few minutes testing resolved all my issues. Thanks for your response.
