Reviews & Research

CNET Editors' reviewMediocre


    Numerous picture controls enable the inexpensive LG LK450 LCD TV to achieve accurate color. Surprisingly for a 60Hz TV, it handled 1080p/24 cadence properly, and its matte screen is a boon in bright rooms. It also exhibited a relatively uniform screen and offers better connectivity than most entry-level TVs.


    The LG LK450's picture quality falls short of its entry-level competition, mainly because it produces a significantly lighter shade of black. Its image also suffers more when seen from off-angle. The TV's styling is lackluster and we noticed lag when using the menu system.


    While the picture quality of the LG LK450 has its strengths, they're overcome by its grayish reproduction of black.

Awewome product! Comparable to SONY !

Yes, I would recommend this product to a friend.

I needed another TV for the kids rec room. I thought the LG brand with its quality reputation would be a good choice. I was right. It surpassed all my expectations. The HD connectivity to cable and satellite systems met quality standards in resolution, sound and color. I highly recommend this TV to anyone looking for a good size flat screen and comparable with SONY.

Remarkable value for the price

Yes, I would recommend this product to a friend.

This is our 4th 42" flatscreen monitor, and by far the best.

It serves our family as the TV, DVD, and Internet monitor. It is connected to our computer as the Home Theatre PC monitor. It is very light, and easy to set up. Connected to a small digital television antennae, we pressed channel scan and now receive over 62 channels of HD broadcasting free. There is no need for any SAT TV or Cable costs.

Our family uses the PC daily, and despite the use, this monitor never gets hot. It is easy to jump between functions. The 1080p DVD clarity is remarkable, and is much better than our previous flatscreen.

A good value for the price, delivered free with no tax.

Awesome 1080p 42" LG HDTV

Yes, I would recommend this product to a friend.

I bought this TV because ours was getting old and we had never had a HDTV before. What a difference in this one and the old one. Best picture I've ever seen and it has so many options that come builtin. The price was also great. I would never have thought I could get an LG brand 42" HDTV with all the options this one has such as internet apps. and 1080p for less than $600.00. There is nothing that I don't like about it. I think it is perfect for everyone and it's not too big or too small. It's just the right size. Thanks LG.

I’m enjoying this set.

Yes, I would recommend this product to a friend.

The set is appropriate for our large family room. With the right connectors you can get inputs from your laptop. This allows everyone in the room to sees the same slideshow or powerpoint presentation. Once I figured out how to make adjustments, I got a fabulous picture.
