Love at first sight
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I was originally looking for a large TV, biggest I could buy, since my space and wall were so large. My viewing distance was 20' and the space was 19' to the ceiling. Think racquetball court. I decided to check out BBY because they had all of the models side by side for comparison. They put the LG OLED off by itself in its own showcase because once you see it the others look so blah. I decided I could sacrifice some size for that spectacular picture. The depth and the contrast was second to none. I haven't looked back. This TV was everything I wanted and then some. A bit more than I had budgeted, but still substantially cheaper than my old 65" Plasma that was 12 years old. My new theater space looks good. It doesn't have much furniture yet, and the fireplace isn't installed, but it is already my favorite room in the house because or the LG OLED television.

LG OLED B3 TV Review
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.We bought this TV to install in our living room, and we are very pleased with the product! The experience is very immersive, and the TV is also very functional and easy to navigate. The OLED technology allows for a very striking picture quality, with the natural colors and contrast being displayed as more vibrant. We thought installation would be difficult, as we already had a 65'' at home, but we were surprised by how light and thin the screen was. It was so easy to install that my 15-year-old was able to do it mostly by himself! While there are many good aspects, we noticed that the Chromecast technology was a bit lacking in quality, and it took a while for the TV to connect with our mobile devices. However, overall, I would strongly recommend this product to anyone looking to buy a new TV.

beautiful oled
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.It's a beautiful TV, I struggled to decide between this and the C3 but I believe the B3 is just as fantastic. I got the 77" and it's massive. If you're on the fence, just get it when it's on sale. Once you go OLED you won't ever go any other type.

Great resolution and sound!
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Great picture and controls. It did take a little while to get used to the cursor. We also purchased the wall mount and service for install. I highly suggest purchasing the installation. Quick easy, the work with you so well! They were in and out in about 45 minutes. Probably saved our marriage in the process! :)

||Posted .

Q: QuestionI moved to Germany and brought my LG - 77" C2 Series OLED 4K UHD Smart webOS TV. (1) Can I use this on a 220v system or will I need a converter? (2) Are there compatibility problems with the U.S. NTSC and German PAL (B/G) systems if I only use cable TV?
