Summary: First...I've had this TV for a year and three months, we quit using the 3D features w/in a month. They just aren't that impressive especially when you ultimately realize that there really isn't that much 3D programming out there. Don't waste your money on that feature.
3D Preload App does not work-TV under warranty - LG support is useless

Summary: Model: 55GA6400 The 3D Preloads are about 17 minutes long. About 2 minutes into the 3D Preload, the app freezes. Sometimes the TV screen blacks out. Contacted LG via email. The support team told me to make sure all updates were done.
Summary: Could not update adobe flash player on the Google Smart tv. That limited the number of app you could use. Was also told by google support that it had the latest firmware but there were problems with it
Summary: I wanted to buy a 55'' passive 3D TV. Currently only Vizio and LG make those. And I also wanted to spend less than $1K. I was leaning toward the Vizio set but it's never on sale. Then Fry's Electronics had the LG55GA6400 on sale for less than $1K.
Summary: I mainly bought this TV for the QWERTY keyboard. I was not able to find any other smart TVs with such a good keyboard on the remote. I do not have a TV connection and only watch youtube videos and play games/watch movies using my PS3.
Doesn't support SimpLink - Works as expected but not a great television

Summary: I really want to like this TV. I'm out of my return period so I can't return it, but here's what I think about the LG 55GA6400. The picture is fine, I don't see a lot of motion blur but we do watch a lot of streaming content so it's already compressed and lower quality.
Summary: As another disappointed reviewer pointed out, this LG tv is great as a tv, however, the other features are a huge disappointment. HBOGO and other streaming apps mostly work, but are cumbersome to navigate and the apps are prone to buffering issues as well as outright hanging.
