PSA: Sensitive To PWM Flicker? You’ll Want To Keep The Switch OLED’s Screen Nice And Bright


Switch OLED Nintendo Life
Picture: Nintendo Life

Nintendo’s newest iteration of the Change launched on eighth October and whereas it’s miles from the long-rumoured ‘Change Professional’, the brand new display screen on the Change OLED mannequin is a phenomenal factor and has led to the brand new Change SKU receiving typically constructive opinions. It does not damage that unbelievable video games like Metroid Dread and Tetris Impact: Related launched alongside the console and actually showcase the distinction and wealthy color of that beautiful new OLED display screen.

Nevertheless, there’s one comparatively unreported concern that appears to be inflicting a problem for a minority of gamers: PWM flicker. It is to do with the way in which the brand new display screen handles brightness by way of Pulse Width Modulation, and at decrease brightness settings it can lead to a flickering impact {that a} small variety of gamers could also be delicate to.

Earlier than we discover the difficulty, we should always preface this piece with the truth that this is not a widespread or alarming drawback and it’ll not have an effect on the overwhelming majority of gamers utilizing Change OLED. Numerous Nintendo Life employees members have examined the display screen and, whereas we will view the PWM impact via our smartphones capturing video at 120/240 FPS, not one in all us is ready to understand a flicker with the bare eye.

Nevertheless, for gamers who are delicate to PWM flicker (we’ll get into precisely what that’s in only a second), utilizing decrease brightness settings with Change OLED could also be distracting sufficient to trigger an issue and result in eye pressure over time.

So, what’s ‘PWM’ precisely, and the way is it utilized in Change OLED’s display screen?

Pulse Width Modulation is a technique of simulating a change in brightness with out altering the voltage equipped to a display screen.

Primarily, when the person lowers the Brightness setting, screens utilizing PWM activate and off quickly at a charge supposedly past human visible acuity. Viewers understand the general discount of sunshine output over time (together with the extremely temporary intervals when the pixels on the display screen aren’t illuminated) as a decrease brightness.

The issue arises for people who find themselves delicate to this fast display screen change and may understand a ‘flicker’.

The video under demonstrates the phenomenon by filming the Change OLED’s display screen utilizing a digicam filming at each 120 frames-per-second and 240 frames-per-second. Many telephones are able to this now, and we carried out related exams ourselves — you can also see the impact by viewing the Change OLED display screen (or every other PWM display screen) via your telephone in the identical method.

Once more, we stress that solely when seen via one other gadget capturing the display screen at a excessive body charge will the overwhelming majority of customers be capable of discern this flicker. For the small variety of people who find themselves delicate to this, although, you will get a imprecise thought of how distracting and straining PWM screens could be.

For context, though this author cannot see the glint on Change OLED’s display screen at any brightness setting, I might say I am inclined to different types of electrical gentle flicker, particularly sure kinds of gentle bulb. It does not occur too typically however put me in sure rooms — typically with strip lighting — and I will immediately be scrutinising different occupants and questioning how on earth they will stand spending any time in any respect in such interminable situations. It is not one thing I’ve spent a bunch of time researching; I merely get the heck out of the workplace or elevator or wherever it’s as quick as doable.

What ought to I do if I can see PWM flicker on Change OLED at low Brightness ranges?

Is there an answer for PWM-sensitive individuals when utilizing Change OLED or every other display screen which makes use of Pulse Width Modulation? Hmm, kinda. It is a straightforward one, in truth — preserve the Brightness setting good and excessive.

PWM flicker is less complicated to understand at decrease brightness settings (when the display screen is popping itself off at longer intervals to provide the specified lower-lit impact), so protecting the display screen above 50% always will minimise that impact.

A display screen at full brightness will naturally enhance the potential of ‘burn-in’ — a subject we have explored earlier than — however the actuality is that fashionable OLED panels are considerably higher at mitigating the dangers of picture permanence than in years previous. Burn-in is a threat, sure, however most likely not one you need to be worrying about except you play the identical recreation for days on finish at full brightness and by no means dock your console.

Sadly, having the display screen at near full brightness always will inevitably drain the system’s battery at a sooner charge — one thing that may have an effect on transportable gamers who’re affected by this phenomenon.

So the place does that go away us, then? Nicely, whereas it ought to completely be famous that this would possibly not have an effect on the vast majority of Change OLED customers, it is also essential to recognise the potential concern for gamers who might encounter it. Finally, when you have had hassle with PWM screens or related light-flicker points prior to now, we would undoubtedly suggest testing a working Change OLED unit earlier than shopping for one — simply to make 100% positive that it is the Change for you.
