Lenovo Legion Legion Y520 running windows 10
I am connected to a Sony TV by HDMI. When I use the TV as the only display or as an extended display the image is downscaled to 720p. If I clone the display from my laptop it will render full 1080p.
All of the settings I can find appear to be correct. The laptop says that it is displaying 1920x1080. I would like to get the TV to work as primary display. I know it is not the TV. It can display the cloned desktop and works properly for game consoles also using HDMI. I have tried using different HDMI ports on the TV.

For new external Display device, on external mode, extend display cannot show 1080p, maybe it is a device compatibility problem. I think you can try to manually set the display resolution, hope below step can help you:
1. Open "Display settings" from right-click mouse menu on desktop.
2. click the entend display device on Display Setting.
3. Scall down and click drop-down menu of "Display resolution" to select the appropriate resolution.
