LG entry level TV is quite premium for the price
I purchased this TV 6 weeks ago. It is a fantastic television, replacing an older 55inch LG LED backlit TV which was still working after 8 years! I use this in a room that does have plenty of outdoor lighting, a window to the left of the television at approximately a 45° angle, and a patio door, about 18 ft to the right also at an angle has the television is mounted on a stand in a corner of the room at an angle? I know this TV is not as bright as the C5 however, we have had no problems with glare or brightness of this B5! With all the features this television has, it's really lacking very little that's significant to me over the higher end oleds. Saved a grand over the C5, and very happy with it.

Awesome OLED
Bought this from LG just before Christmas and I'm very impressed , 4K looks amazing and to my surprise the sound has lots of bad perfect for movies and music videos I must say I didn't expect it to be this good and I have a 2024 QNED86 55 inch in the lounge they're both mad smart TV's but the OLED beats the QNED86 for sound , picture quality is more pure on the OLED but the QNED86 is 120hz so is the OLED so you get what you pay for LG rocks

LG - 48" Class B5 Series OLED
For this product being an "entry level" oled, I must admit the display and the resolution is superb. I have been using this product mostly for resolution mode gaming and the fps on resolution mode gaming varies from 60fps - 40fps which I am okay with. With proper optimization this product will for sure satisfy any consumer who is looking to upgrade from their old set up; of course bearing in mind this an "entry level" oled.

Great TV!
[This review was collected as part of a promotion.] I recently bought a new LG OLED55B56LA TV and I’m extremely impressed with the quality. The picture is stunning with deep blacks, vibrant colors, and incredible clarity that really makes movies and shows feel cinematic. The OLED panel delivers amazing contrast.
The design is sleek and modern, fitting perfectly into my living room. Setup was quick and easy, and the smart features are fast and intuitive to use. Overall, this TV exceeded my expectations and I would highly recommend it to anyone looking for a premium viewing experience at a reasonable price.

A not so 'smart' tv compared to my 2018 LG TV
I was really looking forward to this OLED65B5PSA as it was recommended by Choice Magazine. However, it's range of codecs are very limited so i'm not able to view as many media files as i did on my 2018 LG TV! Instead, i have to connect my laptop to the TV which is very old school
The other inconvenience is the remote and the main interface. The input button does not show the whole list of input options to select from. Instead, you have to scroll to select play media from usb - again my 2018 LG TV remote button provided much more direct access to select
As these were the main major functions i valued in a tv and they've been quite wanting, I've therefore sadly not been happy with this purchase
