yes, it can wall or stand mounted

Absolutely. It uses either wall mounting bracket LSW240B or MSW240. Either bracket will require 4 screws (M6)

Yes wall mountable. Uses standard VESA mount.

Yes this is wall mountable, you have the universal 4 screw holes on the back of the tv.

Yes, this is able to be wall mounted.

I would get the Blu-Ray player in 4K and also, DO NOT FORGET to buy the 4K HDMI Cables!!!!!

Upscaling is a nice option on TV's but it is never as good good as Native 4K content. There will be 4K players and content coming out very soon probably by the end of March. Cnet has alot of coverage on the new tech being introduced at CES in Vegas going on this week. I would recommend a 4K player for the best picture the TV is designed for. The upscaling can be a tad laggy or pixel distortion depending on the source you apply to the TV. Hope this helps

It would work just fine in regular dvd. But if you want the full use of it get the 4K dvd player

Had standard tuning done to my 43" in the living room but a higher level tuning is available - takes about an hour to an hour and a half. They bring in specialized tuning equipment and adjust the TV for lighting in the viewing area. Had it done for my 32" inch in the kitchen last year and it still has an extremely crisp picture even with the overhead lights on.

Yes, the color can be fine-tuned.

Yes, it has a minor delay when viewing it mirrored to my main screen, but not enough to cause my gameplay to be undesirable. I didn't even noticed unitl I happened to see it out of the corner of my eye. I dont think I would use it as my main or only monitor though. Like with most TVs, the white lettering on your desktop icons are not as clear as a normal monitor, but other than that, I have seen no downsides. Can't beat the price for what you get.

Yes, I have hooked up my laptop. Very easy with the right cables and a newer computer.

The thing that sucks about this tv is lack of ports, your only option is to use the optical audio port and hooking that up to your Yamaha, if the Yamaha doesn't have optical audio, you can buy cheap adapters on amazon that go to optical audio to red and white rca inputs.

Did you run an HDMI from the DVD to the receiver? If so seems like there's a problem with the receiver inputs and/or settings

There was immediate answer on this as well. It seems like there really is no difference between the 2. The build quality may be different but spec wise it looked the same.

More features and better design, suppose to have a better picture?

Yes

Yes

I am on direct tv and the lag time is minimal,. I have another LG HD TV in the house and it is much worse with that TV

This is common with digital television sets. It takes a few seconds for the television's engines to build the picture from the data feed.

This television does not have Bluetooth.
