Issue with Iris Xe Graphics Integrated External TV Monitor

I have a Lenovo laptop with the integrated Intel Iris Xe Graphics card. However, I use an old Samsung TV as an external monitor with an HDMI output. Unfortunately, the image is not being transmitted to the TV, even though the second monitor appears in the display settings. The only way I managed to transmit the image was by changing the resolution to 800x600. Could you please assist me?

Use the gnome display settings panel to configure the second monitor.

Your description if sadly lacking in needed details to provide further assistance.
