You should get an LG 22in. TV. The reason you should personally get LG is because the quality of those certain TVs are really good. They can also come in 3D depending on how choosy you are.
The best TV to purchase for a small room would be a Samsung LCD TV. Flat screens are the best kinds of TVs to use in a room which is limited in space.
Depends on the room size you don't want too big or too small.
You'll want a 3D TV since they produce the best 3D images. If its for a large room, you'll want a passive 3D TV that can show pretty wide angles. Might i suggest a LG 3D TV. Two of their TVs ranked in the TOP 5 (1st and 3rd) in a 2011 list from PCworld.
Best Buy sell a complete range of LG LCD tv monitors and they are readily available in different sizes to suit your individual needs such as whether you want a small tv for a bedroom or large for your living room.
A 40 inch LED TV will be best suited for the living room and it will not occupy more space as it is wall mountable and will add style to your living room and will also enhance your status.
A wall TV which stays out of the way is probably the best choice for a kid's room. Children need a lot of room to spread out their stuff or even kick a ball around, so TV on the wall would be safer for both the TV and the child.
The TV's they make today can be as thin as an inch thick, so they don't take up valuable space in your living room and they can also be mounted to the wall by a fixed wall mount. When purchasing a TV for your room follow the rule of thirds. The rule of thirds means the distance you sit from your television should be three times the diagonal screen size.
For a small bedroom a 22 inch LED TV might be too small, however I would recommend something a little bigger for your room. A 26 inch LED would be much more accommodating for your room.
Corner TV cabinets fits in the corner of any room. The use of the corner cabinet required very small space. If one do not have a big room, this type of cabinet is good for small space.
LG has a 21-30' TV that would work really well in a children's room. Most big box electronics stores will carry something that will suit your needs. Best Buy, Walmart, Target etc would all carry tv's on the smaller side.
For a small space, consider convertible furniture. Modern sofa beds and futons are quite comfortable, both to sleep on and to use during the day. The advantages are that space usage can be minimized when the beds are not in use and the family can also use the room as a TV room or lounge when there are not guests staying in the house.
There are a number of mini-VESA mounts for small TV's under 24 inches.
