I don't think the Lite will have the necessary mechanisms to output audio and video to a TV, otherwise they would've kept the feature. It would be better to get a regular Switch, or just wait for the inevitable Switch TV.
inevitable Switch TV ?
I had a reason to believe why there could be still the necessary internal mechanism to output but they prefered to officialy cancel the function.
In 2019, 720/540p are ugly resolution on a big screen, I personnaly would accept to play these resolution from Switch games on a TV, but maybe they did not want to show this in 2019 to the mass, while the normal Switch is already at the edge of the acceptable.
