We've been hearing about the upcoming OLED displays for years now, and it almost seemed like the technology was going to be killed off before it even started. Thankfully, a few companies are pushing forward with OLED sets, including LG, which has just invested $655 million into the tech.

Hisense is among those jumping on the 4K technology boat and they're bringing a new set with a range of sizes. Those looking for a more standard set can pick up a 65 inch version of the XT900, while those looking for more can step it up to 84. If you're ready to go all out and you've got the space for it, Hisense also has a 110 inch screen available.

We can all agree on a few things: UHDTVs look great, the massive sizes make them even more appealing, and that there absolutely needs to be content to watch on them.  Despite the good points, that lack of content combined with high prices left a question as to just how well they'll sell.

When the first consumer TVs to take advantage of UHD resolution were announced, it seemed like they were all going to hover in the 84 inch range, but LG is bringing things down to the living room level.  Their newest 4K sets will be coming in sizes more appropriate to the average living room – 55 and 65 inches.  Prices haven't been announced yet, and we don't expect to see that happen until after CES.    

The folks at Sharp have been touting their new IGZO technology for a while now, and we've started to see it show up on phones and tablets, but the PN-K321 is the first application of the tech to a larger screen.  This 32 inch monitor boasts an Ultra HD resolution and a frame of just 35mm thick.
