It’s there (if the TV is relatively new.). Where it would be in the menu is dependent on your TV model.
I would do a search on “Change Resolution Settings for Brand Model”. That will probably bring up your user manual. You might even find a You Tube video.
Are you using a digital TV antenna?
this a digital or analog broadcast?
Youtube. As much as I dislike the people that run youtube it is the goto for howtos.
Absolutely nothing to do with an antenna, as long as it is not noise.
Sounds like a processing error in whatever box you are using to view it.
I gave up on using antenna. They worked for a few junk local stations but the picture quality was poor. I had to keep shifting the antenna position.
Using Roku now, and it is much better, and equally cheap. Lots of free stuff, and get all main channels albeit with delayed streaming, but quality of picture is as good as cable service providers. Roku requires having wifi at home. Setup is fairly easy. Best of all no more TV bills from Xfinity.
If you are getting 2 signals, that sounds like a problem.

how much is a new sognal?
You need to provide more information about what hardware you are using.
OTA antennas do not connect to a TV with HDMI. Sounds like you may have a separate tuner. The cable from the antenna should be a coax cable with a screw on connector. If so what is it connected to? Does you TV have a tuner? If so it should have a screw on coax connector. What does the HDMI cable to you TV connect to?
Descriptions of the hardware you’re using would help, including model numbers would be even better.
$1000 question:
Did you plug your antenna into a converter box and THEN connect it to your HDMI on your TV???
My beeber got hurt when 3 signals tried to enter it at once.
The HDMI input on a TV is not for an external antenna. There should be a coax style antenna connector somewhere for the antenna hook-up. And as mentioned earlier there is no such thing as a “digital antenna”...any old (but still in decent shape) outdoor antenna will do i.e. the old one you had for your “picture tube TV”.
