Image quality is the biggest asset, but not OLED-level.
After two weeks of testing the LG QNED 65QNED82, the image quality is good, but not outstanding. While my old OLED TV achieved deep black levels, the backlight on the QNED clearly shines through, especially in dark scenes, creating a grayish-blue cast instead of true black. Colors are bright and the details are beautiful, but the contrast can't compare to OLED quality. However, the screen is bright in daylight and suitable for watching TV in a brighter living room.
Sound leaves much to be desired.
The sound quality is the biggest drawback. Voices are still clearly audible, but as soon as you watch a movie with lots of effects, explosions, or ambiance, you immediately notice the lack of bass and depth. This causes the audio to lack warmth and power. For a truly good experience, I recommend connecting an external soundbar or speaker system, as many other users have mentioned.
Usability compromised by privacy and advertising
What really bothered me were the very strict terms and conditions you have to accept to use the smart features. As a consumer, you're not allowed to install your own apps, and LG pushes a lot of advertising onto the TV. The fact that I could see how much data was going to advertising networks and LG itself via network traffic was annoying—fortunately, you can technically block this with a DNS filter, but this isn't an option for average users. The pressure to accept terms and conditions and tracking are serious drawbacks for me. Moreover, the extra buttons on the remote control for services I don't use are unnecessary and sometimes annoying to accidentally press.
Menus and settings - chaos for advanced users, ignorable for regular users
The menu is extensive, but in my opinion, confusing. This won't matter to the average user, as they probably won't adjust anything except the volume, but if you enjoy tweaking settings, it can be a maze. While there are many options, it lacks a logical structure. This makes the device less appealing to users who do want control over their devices.
Price/quality - only the price is convincing
The LG QNED 65QNED82 is attractively priced: you get a large screen size and modern features for a relatively low price. However, the price doesn't justify the limitations in the picture quality (compared to OLED), mediocre sound, and annoying advertising. In this price range, there are other models from competing brands that score better on ease of use, sound, or privacy. Therefore, I would only recommend this TV to those who are purely looking for the size and basic picture quality.
