What People Are Saying

Rated 5 out of 5 by from The right size, picture clarity, and price. We use this as a TV for watching while on the treadmill. Its is the perfect size and projects a bright clear picture. Very Happy

Rated 5 out of 5 by from Great small TV Bought this to go in our updated bathroom. We are news junkies and didn't want to miss anything while getting ready in the morning. Exceeds expectations with all the apps and features. Easy to set up and use. Needed the white for the decor, but the TV is great - regardless of color!

Rated 5 out of 5 by from Great tv This tv is the perfect size for our kitchen. The picture is clear and the remote is simple to use. The sound quality could be a tad better because it seems that we have to in increase the volume in order to hear spoken dialogue. That's why we are glad that it has the written dialogue function .. the set is easy to clean- just the swipe of a damp cloth works wonders.

Rated 5 out of 5 by from Kitchen TV We bought this TV to go in our kitchen. It fits right under the cupboards and gives us a great HD picture even though we don't have it hooked up to cable.

Rated 4 out of 5 by from Works for me! It is great tv with nice quality. The only problem I have is it has no audio output options. I use this in a semi truck and with all the noise around me, it is hard to hear.

Rated 3 out of 5 by from Nice TV This is a nice TV, I needed white for my kitchen and this was pretty much my only option, I like this tv but I really wanted 19 inch but that was not available. This tv is nice looking but the volume is bad, you can go from 10 to 100 and not hear any difference in sound, that I do not like at all, I was very surprise by this flaw.

Rated 5 out of 5 by from Like the color. Difficult to find a white tv. Have only has a short time but don't find any negatives thus far. Some reviews mentioned a volume deficit but I can't agree.

Rated 4 out of 5 by from Good second TV Bought for bedroom to replace an old CRT TV. Good sharp picture and I like its rapid on picture. What I think could be improved is the loudness control (not enough) and the picture contrast controls.

How do I get the TV to connect to my speaker via BT? I don't see a BT option in the on screen display menu but the box shows that the TV has BT.

Asked by: Skip1945
You would not be able to connect the speaker to the unit via Bluetooth. The Bluetooth on the unit would be for the Miracast.
