I have had this TV for two months now. Out of the box it was pretty good, however it seemed lest bright than a 6 year old Sharp Aquos. But after playing around with the picture settings I have this tweaked perfectly. Although th TV sound speakers were good, I also added a sound bar which made it better but not that much, probably not worth th emoney unless you really want thumping bass from a sub woofer. What I find annoying is the remote control, the cursor is jumpy. I rate that remote as one of the worst remotes I have ever used, probably will get used to it but the cursor remaining on the screen for a bit is unecessary. The updates seem to help so allow them. For the money this TV can't be beat. I was going to spend a bit more money and get the OLED but until they figure out the burn in I will pass. I only reason I did not give this 5 stars is that stupid remote. There was nothing wrong with the old school method of scrolling down to find the menu item you needed. I would reccomend this TV

Got this TV from Best Buy and we love it! The picture is beautiful, especially with 4K streaming and movies. The LG magic remote and smart technology is also very user friendly and works very well. Very satisfied!

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

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.
