New TV gives poor quality via HDMI?

Yesterday I connected my new Toshiba TV model name: 55UA3A63DG. I have a little problem, however, when I started my receiver, I noticed that the TV delivers a much poorer quality via HDMI but a much stronger quality via YouTube or netflix. What can I do about it, the receiver settings are also on normal, could it be due to the HDMI cable? I would be grateful for any little help.

Try something out:

Why connect a receiver again? Everything is built in there.

Integrated triple tuner (DVB-T2 HD / S2 / C), TPQ 1900 (Total Picture Quality)

away with it.

Unfortunately, I noticed that the quality is not only this way via HDMI but also with other apps, although I can't quite understand that because it is perfect via YouTube.

This is a 4K UHD screen so look what you have set as the resolution
