I want to say thank you to all the reviewers on here. Like you, I scoured the internet looking for reviews on this TV and only found this thread. Your positive reviews helped me to make my purchase. I bought my Sanyo for $448 at my local Walmart along with the 3 year warranty. This TV is replacing a 1080p 60hz Samsung I currently own. It was only 32 inches and I needed a larger TV for my living room so I decided why not get a 4K? Initially I was going to get the Hisense 55H6B, but couldn't justify spending $370 on a 1080p 120hz when I could spend just $78 more for this 4K. I love this TV. The picture is beautiful. The sound is amazing--no sound bar needed. No problems with black bleeds on the screen as I've read with other brands. I use the preset picture and audio settings. I use "standard" for daytime viewing and "natural" for night. I use "vivid" preset audio. Several salespeople told me 4K wasn't necessary because cable providers and many apps aren't offering 4K content, but with this TV that isn't a problem because it upscales 1080p and lower resolution content to 4K. Is the upscaled content 100% 4K? I'm not sure, but it's noticeably better. I also hear that bluray looks so much better on 4K so that's another plus. Lastly, I want to talk about this TVs smart capabilities. This is NOT a Smart TV. I thought it was when I saw the YouTube app on on the box. It has Netflix, YouTube, VUDU and Pandora and several mini apps and has dedicated buttons for Neflix, YouTube and VUDU, but there is no app store where you can download new apps and games. The 36 mini apps include popular networks like A&E and Lifetime and CNET and TMZ apps were you can watch snippets of shows. I didn't see any live streaming apps. If you need a true smart TV you will need to purchase a Roku or other streaming device. All in all I'm happy with this purchase. I would buy it all over again. I hope this TV lasts for many years.
