I have already brought up some of my troubles with Windows 10 elsewhere, but this place sounds more suitable for a thorough discussion.
I have been using an HP ZBook Firefly 15 G7 Mobile Workstation for about a week, and I am struggling with the high brightness and the intense white background. The OS is Windows 10 Pro, version 10.0.18363 Build 18363. Please let me know if sharing other specs is of help.
I read many complaints about Windows 10's extreme brightness on answers.microsoft.com and other websites.
Here is a list of a few things I checked upon.
The display is nominally PWM-free at all brightness levels.
Blue filter-glasses are of moderate help, but do not solve the problem.
I find some comfort using High Contrast # 2 among the High Contrast settings and red-green (red weak, protanopia) as colour filter. I tested this at night only, and it appears a solution only for reading text. The laptop tends to suffer and activates the fan when I use these settings.
I removed the automatic adjustment of the brightness, which clearly was not working well.
I have been testing Iris for a day, but making the screen more orange has not led to any major improvement. I have not tried their anti-aliasing font type yet, but that is not strictly related to colours and brightness. Actually, the text looks decent to me. It is only poorly contrasted to the background, which does not look even. I can perceive some glowing. Dithering? What is the final verdict on the famous dither.exe program? Can someone please update? Is it worth a shot?
As already reported multiple times in the past, more than once I was able to convert an unusable device into super-smooth on my eyes by lowering the screen resolution from native. I did a quick test reducing the resolution from 3840 x 2160 (250% scaling) to 1920 x 1080 (125% scaling), maintaining the same aspect ratio, but I was not impressed. Perhaps I need to try for a longer time.
When I close the laptop lid and I re-open it, the brightness goes to the maximum value and stays so until I hit one of the brightness keys. It happens all the time. I wonder if updating the OS and the driver via HP Assistant could be a good move, given that I have not been on Windows for 3 years and I do not have a "good" setup to refer to anyhow.
I forgot to mention my symptoms, which are pretty weird. I used the laptop for 3 hours on the first day at night. I got the wildest eye twitching ever. Other muscles quickly began twitching as well, such as between my arms and shoulders and my oblique abs / low back. Neck pain started immediately in correspondence to the cervical spine. Within a few hours, the inflammation had spread to my all body. Since my second day, I have mostly had sore and inflamed arms and neck. I never had issues with my arms before! The most puzzling thing is that, besides the eyelid and facial muscle twitching, my eyes are not that bad. I can move them around quite freely, and I feel instantaneously better if I stop using the laptop, or I read on an old Kindle. This is in stark contrast to what I experienced less than a month ago, when I was completely knocked down for a week by just looking at a car display for 30 minutes or playing with a Microsoft Surface Laptop 3 15 inch (13.5 inch was okay).
I forgot to mention that, after day 1, I have been using the laptop 10-14 hours a day. Maybe too much for a start. Symptoms have sort of stabilised after day 1, but I do not know what to await for the future. I am not positive about all the twitching that is going on. My body is clearly not enjoying and is sending out messages.
I appreciate any advice. Thanks.
