Would like to check... is latest model Samsung smart TV come with HyppTv apps installed? Thanks.

How can I mirror my phone to KU6000?

TV must connected thru wifi?if LAN cable cannot?

Of course u need to connect ur smartphone to the WiFi unless u connect ur smartphone thru LAN, but if u use Samsung phone with Samsung TV, u can discover nearby TV even without connecting to the same network for screen mirroring.

No shit Sherlock! 
Who said anything about connecting the smartphone via ethernet cable? Fella posted about connecting the TV via ethernet cable. And yes, that will work and with compatible devices, it is automatic.. It's been around for years. TV connected via cable to router and phone connected via WiFi to the same network. FYI, LAN stands for Local Area Connection. So, connecting to a wifi network also establishes a LAN connection.. You may want to actually know about stuff before commenting as if others are dumb.. 

Btw, is it better to 'shutdown' the TV before turning off the power?
I usually just switch off the power plug when the TV is still on.

Powering down the TV through the remote before physically turning off the switch is recommended as TV has become complex and powering down allows "some" functions to go to standby mode.

Killing the power is not supposed to happen unless you know, your electricity got cut off.

Put it this way, for your desktop you dont want to kill the plug power before you shut down Windows right?

Well said
Basically need to shut down first via remote control

Quoting from other Forum I'm reading in relation to killing the power

"In the case of a digital television, you're talking about a power transformer inside the set that is really rated to handle those peak voltages, even at startup - but over time when you constantly subject a component to that spike it simply ages quicker.

The short answer is - no, you can't damage a digital TV by using a power strip to turn it off (especially if it's a high-quality surge protector), but yes it can age the set more quickly by putting the power components in the TV under a little more stress than they need to face."
"Electrical it's not advisable: You will certainly shorten the life of the power strip and or switch until it is damaged.

Whenever you intercept a circuit (using a switch or pulling the cord) an electric arc is created. Usually this arc exists only for a millisecond (or less)."
So basically, it won't spoil your set instantly, but it may cause some "degradation" to the power supply (the one that takes the 240v and convert to electric that your TV needs). It will be minor degradation but it will compile over time and in the long run it may cost problem.

Guys, just bought a UA55KU6000, quick q:

1) There's no Games tab in the Smart Hub. How to enable it?

2) The antenna connector is RF. I plan to buy a Yakaki digital antenna, but the cable type is RG6. How to connect?

3) I hooked up a 4tb Passport NTFS external hard disk, it can browse the content but when I tried to play, it says unsupported format. I copied the same video to a usb NTFS thumb drive and it played flawlessly. Why?

4) How can I play a file from a network share with this tv?

Thanks

Samsung Support has released new firmware 1123.2. Has anyone already updated firmware to 1123.2?  Any changes or improvement?

Has anyone tried this?

Well that is just your opinion.

I have a 65" KS9000 mounted on the wall of my home and I have friends who have 65" C6s mounted on the wall as well and it looks just as great if not better IMO. But I will not knock you on your preferences. After all this highly depends on one's taste.

However, FYI it is not difficult at all to mount curved TVs on the wall or panels. I DIY-ed it myself and helped my mates as well and each time it was no more difficult mounting a curve as compared to mounting a flat. Flat or curved they all come with the same standard VESA mount interface. Please stop spreading false information if you've actually never done something yourself before.

Impossible, Vesa mount exist since 2006 and nowadays all mount is VESA mount. I don't think u can find non VESA mount anymore.
