We bought a 28 inch LG led TV but had to return it because it did not have any outputs; none! Keep that in mind in your search.
So we bought a 28 inch TCL Roku smart TV which has as good a picture and many outputs to a sound bar or headset or whatever. All TV's have cra**y sound (speakers are small and in the back) and this one is no different but hooking it to a sound bar helps.
P.S. haven't used the Roku system as the TV cannot seem to find our home Wifi so I wouldn't count on it. When you get closer to a decision check the internet for comments. I like Amazon because they note the number of reviews. It there are several thousand reviews it sort of shows the people like the product.
