you can certainly bring in TVs on delta in their original box. 32 inch TV can be checked in as luggage. the bigger Tvs that come in bigger boxes that exceed the allowed dimensions (I think 65 inches total=Length+ width + height = total allowable) can be checked in for an additional 75 dollars. the rest, like 55 inch TV boxes will have to be checked in as cargo.
It is not cost effective to bring in a 55 inch TV or bigger from usa. the chances of it getting damaged in the transit is very high. then in addition to shipping cost in the airline, you would be subjected to around 48% tax / custom upon arrival in DR. No warranty will be served in DR.
Now my 55 inch Tv set me back 47 thousand pesos with 1 year warranty on parts and labor. I am very happy with the purchase. The picture quality is unmatched by any 1080p tv I have ever seen. now the latest models come with 64 bit quad core processors which help open up apps in TV with a snap. The whole Tv experience is very snappy and i feel like I am using a fast laptop. The browser is good and works as designed. I am able to see rt news on full screen. I was even able to watch a pay per view event on the browser
www.zonadeporteshd.tv. they have all the latest UFC and latest boxing ppv fights for free.
so I didn't have to connect my laptop via HDMI cable, the TV is almost a computer and the browser helps me see whatever I used to see with laptop connected via HDMI cable.
Now the USB port is also a very good way of seeing movies on usb drive. My USB 3.0 drive was able to play a full 4k video smoothly. I was able to see 1080p videos, up-scaled to almost 4K like resolution without any hiccups. the video player is great and even plays the MKV video file format. The resolution was great and almost seemed as if the movie was being played in 4K. The samsung video player gives you the option to choose audio tracks (example: if the movie has english and spanish audio tracks). The video player also lets you choose subtitles embedded in the video file. I mean, what else anyone can ask for? My previous sony 46 inch 1080P HD Tv didn't do any of that. slow as turtle, the browser was so slow that I considered it useless for viewing anything. netflix would take forever to open up. no MKV files played on the video player and no choice to pick audio or subtitle tracks. Even some regular video formats had trouble playing smoothly. In comparison, the new samsung 4k smart TV is light years ahead of the TV made just a few years ago.
