This TV is great to start off or if you donÕt want to spend 3,000-4,000 for a OLED 4K TV. The only down side for this TV is the black level. ItÕs still a little grey.

The 1st LG (60UJ7700-UA) I bought at Best Buy in Heath Ohio, was defective, the picture would go black, and the audio was intermittent. I returned It, and brought home the same model. We set it up yesterday, and it seems to be working fine. It was a hassle getting the TV back to Best Buy, and of course, I wasn't sure of the 2nd one would work properly.

I bought this TV and an LG soundbar at the same time. Love both. The only issue is that the because I am using the stand instead of mounting the TV to the wall, the sound bar cannot sit in front if the TV, because it blocks the remote sensor. I have placed the soundbar behind the TV, but am not sure I am getting the full rich sound from the soundbar now. I would have thought LG would have designed their soundbar to fit better with their TV's.

Best choice!

So happy with this tv. Crystal clear picture and so man ways to customize the color. Easy set up...literally took 20 minutes from box to ready to watch! No regrets!

Knie Price Match Policy

Low Price Guarantee

Found a lower price? No problem! We match all local competitors’ prices, just give us a call or email with what you’ve found

(815) 626-5631

Price Match Policy

We’ll match any local competitor’s price on an identical item. We’ll need to verify the price. Any store within 30 miles we consider “local” competitor.

Why just match the price, why not beat it?

In addition to our price match policy you get the advantage or highly trained sales staff, and our professional and experienced delivery team.  We won’t ask you to pay more, but we can’t  provide our advanced level of service and always beat our competitor’s pricing.

Why don’t you match ALL web prices?

There’s little risk in buying books and shoes online. Not so with furniture, appliances and electronics. We’ll match any local store (whether they offer Knie’s level of expertise or not), but there’s going to be a modest price difference between local and web-only stores. If you find a difference you feel is excessive, bring it to our attention; we want your business!

Our well trained sales professionals are also here to provide you with the information you need to make an informed decision on your appliance, electronics or furniture purchase.

How can Knie’s compete with national retailers?

We belong to the Nationwide Marketing Group, a collective of thousands of retailers like Knie’s across the country. Together we have more buying power than a top-ten national retailer, and we negotiate accordingly.

Give me the complete details.

    •    If you find a lower price on an identical item at a local competitor’s store or website, we’ll match it
    •    Pricing not listed on websites must be verified via phone, print advertisement or written quote
    •    May not be combined with other special offers not available at the competitor
    •    “Local” competitors are those in the same city or within 30 miles of a Knie location
    •    Limited quantity specials, closeouts, and damaged/as-is items are excluded
    •    We reserve the right to limit quantities


Knie's offers great quality Furniture, Appliances, Electronics and Mattresses at a low price to the Sterling and Polo cities and the surrounding areas.
