I have had several brands of tvs but my last 3 TVs have all been loyalty to LG. But this one seems much tougher to get the picture quality that works across multiple platforms. i.e. Xbox. Directv. Blue ray. ItÕs only been a few days so IÕm gonna keep trying to get it where I like it.

This television is unbelievably clear and the sound is incredible. I was asked if the sound was a surround system connected to the tv. Their jaw dropped when I said no it's from the tv. The features and apps makes it easy to have fun and have access to tons of entertainment. I own the LG G6, front load LG Washer and Dryer and now this set. LG is doing awesome things and I'm glad......

I'm using 65SJ850V as monitor and game TV Issue that on this model some single colors (yellow , light blue etc) are shown as set of alternating lines. These lines are recognized from distance up to 1.5 meter and very frustrating during work at this TV Issue is general for this model

Great look, sound, and content

I have never bought a TV for this price but IÕm glad I did. The picture is beautiful, the interfaces are user friendly and the setup is easy. I got the 65Ó and it looks amazing in my living space.

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.
