A:AnswerYou can easily fit it in the back seat of most mid-size cars, or if you can drop down the rear seat to open it to the trunk. The TV is about 48” x 28” x 2.4” (without stand). The box is about 52” (longest) by 32” wide. It’s not too heavy, just over 45 pounds.
You do not need an SUV or pickup or a big car to pick this up yourself. The other answers said it is 55” long which is wrong - only the diagonal dimension is 55” (from top-left corner to bottom-right corner). That means its max length is smaller than 55”.
A:AnswerDigital optical sp/dif is not a speaker output, It carries the low-level signal from the tv to an A/V receiver or soundbar. Then you go to the speakers if you go with AVR.
A:AnswerI believe the speakers are pointed down. Not forward or back. As a result, the sound has more low end frequency (bass). Although the sound was better on this TV than my previous model, I ended up purchasing an inexpensive soundbar to help hear dialogue (voices) on some channels. Hope the info helps.
A:AnswerThere does appear to be a Sling app, but it is not pre-installed. Select apps from the home screen and search for Sling. The app can then be installed and saved as a favorite.
A:AnswerI believe this particular Samsung QLED TV model came out in the Spring of 2018. I have read that there were some slight changes in the 2019 version. People familiar with both the 2018 and the 2019 versions, seem to prefer the picture produced on the 2018. Hope the information helps.
