no, you would have to hook up a streaming box to it like an apple tv, roku, chromecast, amazon fire, or a game console such as a wii, ps3, ps4, wii u, xbox 360, xbox one, or your mobile device or laptop.

No, but I bought one of those boxes that stream Netflix from the wireless modem and it work great.

The width is 29". :-)

I pluged in my Creative GigaWorks T40 Series II speakers in the back 3.5mm output,and they worked great.Then I pluged in just my head phones and they worked perfect,with the tv being in exturnal or not they will work.

No 3.5 mm audio.

No

If your going to use this as a monitor,Dont rename your HDMI input to anything,just leave it at HDMI 1 or 2. Turn down the sharpness 20 or lower,if you dont, your Text will look very bad.Turn sharpness down when you have the computer screen on. Hope this helps,it did for me.

Yes but only with HDMI. It does not have a VGA input.

Just put a small piece of electrical tape over the red light. It will blend right in, problem solved.

I own 3 Samsung TV's and they all work this way. The light is on when the TV is off (I guess so that you can see it in the dark) and off when the TV is on, I think so it doesn't detract from your viewing experience. One of these TV's is in my bedroom and it has never been a distraction for me once my eyes are closed. I love all my Samsung TV's (the oldest is about 6 years old and as good as the day it was purchased)!!!

What input & outputs do you have on your Bose (HDMI, component, composite (yellow, white & red))? Ideally if you have the proper connections everything should go to the Bose then the Bose is connected to the TV.

You can buy a HDMI switcher to hook up multiple devices to this TV's limited inputs. You could use this and then use the TV's audio out to connect with the Bose. You can also get a component switcher if need be. Either can Be purchased from Best Buy, Amazon, Walmart, etc. there are inexpensive models to outrageously expensive ones.

Component issue: hook up a device making sure you have the color connections correct then turn on that device, then turn on TV. If that doesn't work you need to check your cable. You can use a composite cable (yellow, red, white) to check. Hook this cable up to the red, green blue component inputs. Make sure it is the red with the green & blue and not the red and white. Make sure you match what color you are using on the TV & device. If this works you have a bad cable if not your TV has bad inputs.
