Reddit mentions of LG Electronics 32LB5600 32-Inch 1080p 60Hz LED TV (2014 Model)

A good monitor at that size and price is going to cost too much.
For $200-$300, a decent TV is a much more realistic option.

For 32" this LG or this Samsung are both ~$250.
For 40", you're looking at the low 300 (that same LG model)+.

That's a 24" Vizio 1080p LED LCD..


If you have $50 more dollars and if you have Prime.. I HIGHLY suggest getting this

It's an LG 1080p 32" tv!!!

If you don't have amazon prime.. if you're a college student or know someone who is a college student .. Ask them to help you out. A person with a student email address can get 6 months of amazon prime for free!

This TV is pretty nice

what about this Amazon says it's the newer model and it only costs $250?

$1000 - The best ones for that price on the market currently is either a 50 or a 55 inch Samsung 6350 series. They cost $947 or $1040 respectively. They have great specs, even better reviews and are gorgeous in person. If you set it up correctly, its picture quality is pretty ridiculous for this price range, it makes me wonder why people ever buy way more expensive TVs.

Another option would be the just released two weeks ago 50 inch Vizio P series. It is the best cheap 4K tv on the market now. That being said, the Samsung above is better in every measurable way except for resolution. Since, there wont be much 4K content for a few more years and 4K is worthless unless you plan to sit really close to it (<5ft for a 50 inch). I would go with the Samsung and wait till my next TV to go 4K (or fingers crossed OLED).

If you want bigger, I would go with the 60 inch LG 5900 series for $929. Again not as nice as the Samsung, but a really good TV for the price. One problem though is the stand is weird and you'd need to either mount it or own something wide to put it on.

Under $300 - This is actually a booming market these days, there are a lot of good options depending on what your needs are. The best two sets available are the 32 inch LG 5600 series for $279 and the 32 inch Samsung 5000 series for $297. The one caveat is that neither of these are smart TVs, if you need smart features I would go with the $298 Vizio M322. Or you could go with the LG and buy a Chromecast or Roku.

Personally I recently bought the $348 Samsung 5500 series for my bedroom and its the nicest small TV I've ever had. It works great as a second monitor (although any of these should).

Here is a 32 inch 1080p TV for ~$270;

You can upgrade from a PS3 to a PS4 if you want, but i wouldn't recommend it unless you have friends who already own one. Many PS4 games actually don't run at 1080p anyway (Call of Duty and Battlefield for example, only display in 720p to get a higher frame rate). If you want to play games at 60fps in 1080p, then the only real option is to save up for a gaming pc build (or build one for ~$500), and use Steam's big picture mode and DS3_tool to support your controller.

*EDIT; never mind, accidentally looked at Xbox One specs, but still, future games will most likely get downsized to 720p for the PS4.
