Hi @IrdinSilverbow,
You can play MSFS 2020 on a TV. I have mine connected to my 55" HiSense UK7. Couple of points:
- Make sure your HDMI cable rating equals or is greater than the HDMI rating of your TV, especially if running in 4K.
- When MSFS 2020 starts for the first time with the TV connected, it may display on your laptop screen. If in full-screen mode, just Alt-Enter to have MSFS change to windowed-mode, drag it over to your TV, then Alt-Enter back to full-screen. MSFS usually (but not always) then remembers which screen to display on. On my PC, it first always opens on my primary display, then switches to my TV once the initial loading is complete.
Hope this helps.
