What reviewers didn't like

We noticed that QLEDs tended to have problems with color contrast and deep blacks when watching them at odd angles. Samsung solved this problem by adding anti-reflective screens to every 2018 TV ... except the Q6FN. A
The Q6F isn't flawless, however. Viewing angles are a bit disappointing, with noticeable color shifting setting in when viewed even 45 degrees off axis. Backlighting also isn't quite uniform, with minor shadows in the corners of the screen.
HDR performance has limited effectiveness
Unfortunately, the image loses accuracy when viewed at an angle.
TV’s local dimming technology is really poor, with only limited dimming zones and because of this, it suffers from noticeable bleed-through and halo effects during sequences in which brightly lit content is contrasting with dark backgrounds.
- 4K
But unfortunately, comes with local dimming technology, its local dimming is not effective to boost its native contrast ratio.
You may need to run firmware upgrades to make the most of the smart options.
