Until you’re an enormous AV-obsessed nerd like myself, you could not know what banding really is.

OLED banding is a kind of show defect that’s precipitated in the course of the manufacturing course of. As a result of not all TVs are created equal on the manufacturing line, no two screens will ever be similar, even when they’re the identical mannequin.
OLED screens are self-emissive, which implies totally different pixels on a panel might be brighter or dimmer than others; that is the first reason behind banding. This defect isn’t restricted to a single TV producer — I’ve returned LG, Phillips, Samsung, and Sony OLED shows on account of banding.
Vertical banding is most typical on OLED TVs and manifests in a method that isn’t solely totally different from the “Soiled Display screen Impact” (DSE) on LCD panels. Whereas DSE produces noticeable blotches on LED shows on account of some panel areas being brighter than others, banding seems as skinny vertical traces. These are simpler to identify in darkish scenes, the place display brightness is mostly 5-10% above black.
Why display uniformity is vital
Like video video games? Banding might be tremendous annoying
Easy gradients/uniform backgrounds may also make vertical banding clearly seen, notably throughout digital camera pans. What content material will coax out banding points probably the most? In my expertise, that must be sure live-action sports activities (particularly ice hockey), and enjoying video video games the place you’re continually panning the digital camera throughout blue skies (as is widespread in lots of open-world titles, like Shadow of the Colossus or Pink Lifeless Redemption 2).
Rockstar’s outlaw epic is probably the one sport I can consider greater than every other that makes vertical banding notably straightforward to identify on an OLED TV. Arthur Morgan’s Outdated West world continually encourages you to slowly shift the digital camera to admire the blisteringly blue skies above its rolling prairies. On panels with poor display uniformity, the place explicit sections are brighter than others, vertical bands can show oh-so distracting if in case you have a eager eye.
When obsessive TV dweebs like me discuss “the panel lottery” on boards, they’re referring to the truth that some OLED screens might be blighted with worse banding than others.
I’ve despatched again an embarrassing variety of OLED TVs over time, swapping them in the course of the return interval till I discovered a panel with a degree of banding I may dwell with. You’ve obtained rather a lot to reply for, Arthur. Fortunately, this superior accent made my OLED TV so a lot better, even once I was affected by the banding blues.

In brief? Typically. Whereas no massive OLED TV goes to have a wonderfully uniform panel, based mostly on my previous unhinged experiences of returning OLEDs at an alarming fee, it’s greatest to not choose a display straight out of its field. Usually talking, OLED TVs take a short while to settle in. For those who spot notably unhealthy banding shortly after unboxing your show whereas viewing YouTube take a look at patterns that test display uniformity by way of grey-scale exams, attempt to not instantly freak out.
As a substitute, it’s greatest to provide your new TV time to settle. After round 100 hours of regular display utilization, your panel ought to hopefully look extra uniform, with clear gradients and darkish areas showing versus whenever you first unboxed it.
You may additional assist scale back banding in your OLED through the use of panel/pixel refresh cycles. Mentioned cycles are one of many methods fashionable OLEDs stop burn-in, however they’ll additionally assist scale back banding when you run them each day over various weeks.
With some producers, pixel-cleaning options should often be manually enabled. With LG OLEDs, although, a panel refresh will kick in after 4 hours of steady use (supplied it’s in standby mode). In fashionable OLEDs, this course of sometimes takes solely round 10 minutes and may actually assist scale back banding over time.
Banding points stay an issue for OLEDs

I’ve but to come across an OLED TV that didn’t have no less than a bit of vertical banding. Fortunately, pixel cleansing cycles are simpler than they was, and generally, I’ve discovered that as OLED expertise has improved, banding points have lessened.
For instance, my present LG G3 OLED from 2023 has a lot much less banding than the LG C1 OLED I purchased in 2021. Banding doesn’t blight OLED panels fairly as usually because it used to, however it’s nonetheless a display subject my eyes are continually looking out for.
