SAMSUNG QA50QN70HAJXZK 50-inch 4K Smart TV Review

T. Y. Chan 25/05/2026

Ordered from BBE and received it next day. The NQ4 AI processor does a fantastic job upscaling older 1080p content. HDR10+ Adaptive works perfectly in my bright living room. Best purchase this year! 👍

De****p 15/03/2026

Packaging was super secure and delivery was fast. This Samsung TV is amazing for gaming. The Game Bar makes it so easy to adjust settings on the fly. Highly recommend this model for console players!

Mrs. Cheung 10/05/2026

BBE嘅CS答問題好pro,幫我比較咗幾部。最正係有7年Tizen OS升級同Knox security,唔怕部機好快outdated。AirSlim機身好薄,掛牆一流,成個vibe即刻高級咗!

Be*****k 10/04/2026

NQ4 AI粒晶片真係有啲料到,睇舊片upscaling效果好自然。Mini LED夠光,色彩好vibrant。BBE包裝得好穩陣,無撞花 😊。

K. Y. Wong 18/12/2025

Love the AirSlim design, sits so flat on my wall. Tizen OS is smooth and has all the streaming apps. Delivery was next-day as promised.

Er*****g 12/08/2025

BBE送貨超快,裝機師傅好專業。部機打PS5一流,有120Hz DLG打芒好順,Mini LED隻黑位好堅,直迫OLED!

Mr. Ho 30/11/2025

Mini LED對比度真係無得輸,但內置喇叭20W比較普通,要另外加soundbar。BBE在線CS答問題好有耐性。

K. H. Lau 20/03/2026

Excellent service from BBE. Fast delivery and the TV setup was done in 15 minutes. Great picture quality!

Mi******g 05/10/2025

Super fast delivery from BBE. The 4K screen is incredibly sharp and beautiful. Highly recommend!

Ra*******t 18/04/2026

The picture is great, but the sound is lacking. Need a soundbar. BBE delivery was on time.

Ga****k 15/05/2026

Only 3 HDMI ports is not enough for my devices. Otherwise, TV is fine. Shipping was fast.

T. C. Lau 05/01/2026

TV is good, but delivery was delayed by two days. Disappointed with the logistics.

Mi*****g 02/04/2026
