Firstly I want to introduce to myself to this community! My name is Stephan and I am one of you, suffering from most modern lighting and devices, due to a hemiplegic migraine, it's neurogenic effects, astigmatism and more.
My problems started at the end of the 2000s, a time when this forum probably didn't exist and probably the time when 6+2FRC was introduced?
Since I was not aware of all the details sorrounding this topic and pretty young by that time, I didn't give this phenomenon too much attention and ended up in pretty frightful situations. Why? Because I was also not aware of my neurologic condition back then and attributed every single detail of what I was experiencing, solely to my undiagnosed health condition.
Then the time followed where AMOLED and OLED were introduced. I remember happily using my iPhone 6s for over 4 years, when I received an Samsung S8 as a present. I sold it in one week.
After that, as time passed, I someday decided to go for the Samsung S10, which I liked and used for a few months, until I ended up in strange situation of vertigo and a so unnatural perception of my sorroundings, that I almost felt like living in a glitch.
So back I went to the iPhone, still struggled with my old Dell Latitude, which by that time did use PWM for regulating the brightness of an IPS panel. Yey. Let's say that all these factors drove me into a crazy health issue, or heavily agravated my condition.
Meanwhile I kept my eyes open and I do personally know otherwhise healthy people that drastically changed their behaviour, after switching to OLED iPhones or AMOLED Samsungs so I pulled the emergency brake.
I am not saying this is some sort of conspiracy going on, I just believe that as with every invention, there is good and bad. Maybe though, the bad aspects of these new technologies are becoming a struggle for humanity. Stroboscopic effects as with PWM might become a hazard for every human being, since long time exposure might damage the brain.
Given my condition I am in high stress even while entering a supermarket nowadays, start to have vertigo and sometimes almost faint, exactly due to this combination between my hemiplegic migraine and the new LED lightings, using PWM. The problem is that everybody starts to act different, while being exposed to these modern lightings, but do not realise it. If you stay aware and keep your senses focused, you will see what I am talking about.
I have personally ordered halogen bulbs, which are costly nowadays, but have brought back my cozy lovely atmosphere that I enjoyed every evening for the decade prior to the LED invasion that occured.
Switching to LED destroyed the pleasant moments I was heavily depending upon, given my condition, without me even realising it.
………………………
In the past years I have tried a multitude of smartphones, laptops, even switched to MacBooks, which made everything worse and ended up contacting different manufacturers for more information regarding the panels they use in their products, after buying and sending back tens of devices.
'Drums please' - I found it! Here it is , right in front of me and I am extremely happy that I bought it! It is the device I am writing this post from and I have been using it for 7 hours now, without even thinking about shutting it down until bedtime.
It is the 2024 DELL Latitude 7450
What makes is so special, next to being a beautiful and really well build device? The panel of course!
DELL was the only manufacturer that offered detailed specifications about the panel choice and yes, the problem is the temporal dithering / FRC and not Windows itself.*
In this model, they have two 400nit panels as an option, which are indeed true-8-bit ones!
You can look up the spec-sheet, here: https://products.b-cdn.net/Brochures/1081065572.pdf
I have found no other manufacturer using or even specifying a description such detailed about their panels. Even the Thinkbook P14s, which carries the best TÜV Rheinland Certificates does not even come close to this DELL Latitude. The Thinkbook P14s was on of the worst Windows Laptops I have tried.
So apparently the DELL Latitude 7450 which I have ordered, the one without the touch-capable panel (matte only for me), does come with a panel produced by BOE. More exactly the: BOE0B18
For the exact specs: https://www.panelook.com/NE140WUM-N6F_BOE_14.0_LCM_parameter_60510.html
So if you want to opt for the DELL Latitude 7450 be aware that only the 400nit panels are true-8-bit ones. The official description should be DELL Latitude 7450 GV98K.
Of course, it might be possible that DELL also uses the BOE0B18 panel in other laptops. You have to check for that yourself, if interested.
I hope that this information could help you!! Thanks for all of your work and for the existance of this forum, which helped me tremendously in finding a solution!
*Windows is natively giving out an 8bit colour range, which can be changed in the display settings to achieve 10bit by using dithering. Of course, most of us, have stayed away from that feature.
Imagine what a typical user encounters when buying an 6+2FRC (hardware) panel notebook and decides to turn on that colour management feature, for more vivid and pleasant colours, which adds another +2FRC by software. Pain!
