the 84LM9600 for 5800 and then we have the 84UB9800 for about 10,000
is there a major difference between both?
what are other good options for a price range within 6500 dollars.
The 84LM9600 was LG's first gen 4K Tv that hit the market in late 2012. The 84UB9800 is their second gen replacement set that hit the market a few months ago. The major differences (out of the box -- more on that distinction below) are:
* The 9800 has all the latest standards that are either required now or expected to be required to play 4K content. HDMI 2.0 inputs (versus 1.4 for the 9600), HEVC decoding for streaming sources, 4:4:4 color sampling support and HDCP 2.2 copy protection. HDMI 2.0 will definitely matter. HEVC is already necessary to stream Netflix in 4K and will likely be the standard for most or all streaming sites that have professional (versus YouTube) content. The benefits of HDCP are theoretical at the moment since nothing yet uses, but the 4K blu-ray players expected late next year may.
* The UB9800 uses LG's newer WebOS user interface which has more apps and is generally considered a nice UI.
* The UB9800 has built-in Harmon Karman front-firing speakers on either side. Vastly superior overall sound quality, but if you plan to use an AVR for sound an unnecessary appendage.
* The LM9600 has had issues reported by many with audio getting out of lip sync track with the video and with some visible vertical banding of the image. So far these issues have not been reported by users of the newer UB9800.
* The later model cycle LM9600's have only 3 HDMI ports while the UB9800 has 4.
If that were the end of the story I would say avoid the LM9600.
But I qualified "out of the box" above for a key reason. LG has started offering a $500 upgrade for the LM9600 where they send a tech to your house to install new boards in the panel. These boards fix many of the above issues, including adding HDMI 2.0, 4:4:4, HEVC (and therefore Netflix 4K capacity), 4:4:4 and the lip sync issue. Not clear yet whether it fixes the banding issue which only impacted some people anyway. They have started releasing this on the West Coast so it may take a while to reach your market.
All that said, one other important note. When you compare $5,800 for the LM9600 to $10,000 for the UB9800 it's apples-to-oranges. Assuming you're using Amazon, the LM9600 is now only sold by third party merchants on the Amazon website while the UB9800 price you see is basically full price from Amazon itself I suspect (or one of a handful of their merchants who sell at the current manufacture's suggested price). However if you go to any of the price comparison sites, for example the Shopping tab on Google, you'll see the street price for the newer UB9800 is really between $6-7K from the same kind of merchants that are selling the LM9600 for under $6K. So from an apples-to-appples merchant, the price difference is usually within $500 gave-or-take, which is the cost of the upgrade for the LM9600. Which is why, barring a special deal you find somewhere, I would get the UB9800 of the two and save the upgrade hassle and still end up with the better speakers. The downside of most of these vendors is they will not have a return policy though. BTW, Amazon price-matches some places including Best Buy, and they have the LM9800 for $9K.
