Rated 5 out of 5 by from Replaced my 32 inch TV! I received this for Christmas! I love having a Smart TV and we are very happy with it.

Rated 4 out of 5 by from Nice picture Have had it for a month now. Nice picture and sound. Had to buy different legs because the legs were too far out for my tv stand. Also a little difficult to learn it's features such as the apps or screencasting. Overall nice tv for a relatively decent price.

Rated 3 out of 5 by from Just so so First thing I noticed is that the remote sensor on the tv is underneath it, I bought an LG soundbar to set in front but I can't, it blocks the remote control operation. Second is I can't get good contrast on blacks and darks, they wash out too easy.

Rated 5 out of 5 by from Beautiful Color, Voice assistance is outstanding. We started looking at 35 in. TVs for a bedroom and ending with the 43LJ550M. The access to apps are so well done, easy to access and operate. The colors are beautiful and the voice assistance is a great feature as the operations are learned. We are very pleased with this purchase.

Rated 3 out of 5 by from nice tv but lacking in basic app availability just received, excited to get a smart tv so i could use my roku elsewhere... turns out this model doesn't support Sling TV. guess that's my bad for not checking more detailed but a new tv with the newest WebOS would be expected to include one of the most popular apps around for cord-cutters. Disappointed.

Rated 4 out of 5 by from Nice tv - good picture but lacking some features Bought a older LV tv a year ago and like it. I like the channel plus channels it had because I have below basic cable. This TV does not support channel plus. I thought all lg tvs hat channel plus , I was wrong. This tv also does not have Bluetooth for speaker output, only optical connection. These 2 options would have make it Six stars.

Rated 4 out of 5 by from Very good features I bought this product 2 weeks ago. I totally enjoy the clarity of the picture and the resolution. The sound quality is good. However this is the first smart TV I have owned and was a feature I was looking forward to. The instruction manual is not very good. It explains very little of the T.V.'s operations. In short the product is very good but the instructions are poor.

Rated 3 out of 5 by from Nice features, color not good. Nice size, nice features. Only difficulty is that the picture is dark. It is not crisp and bright like my other Smart TV's. It is a disapointment, I expected more from LG.

when will sling tv be available on this model?

Asked by: CDNash
The Sling TV app is available for all 2016 webOS 3.0 and 2017 webOS 3.5 LG OLED and UHD Smart TVs. Although the LG Full HD 1080p Smart LED TV - 49" Class (48.5" Diag), Model # 49LJ550M is a webOS 3.5 TV and is not listed as a model that supports this app, you can still use the Sling TV service via other devices such as computers and smartphones, or you can enjoy its service on your TV screen by connecting those devices on which Sling TV is available to your LG Smart TV...^IFV
