Fizeau - Adjust color of your Switch screen

guily6669 · Jan 22, 2020

I'm still to see a LCD where the black is actually black lol, you mean a bit gray blacks... This ain't OLED...

Also there's probably many different LCD manufacturers for the switch and very different color calibrations and no way to fix or change anything since nintendo doesn't have the settings to do anything, to correct white, colors...

Looks like there has been a mixup with 1.1.0, where the release zip didn't actually contain the latest version -- despite its commit hash showing otherwise (go figure). I updated the files, let me know if you run into any issue.

Does this also Work with sx os ?

Of course not.

Wrong, it works fine on the newest SX OS.

Are you sure? Is there a 3rd party sysmodule support in sx os?

Yeah they apparently enabled it in latest versions when they updated their atmosphere code. Maybe by accident.

so are all sysmodule working now in the latest release?

Heh, good to know, at least. I'd also like to remind only Atmosphère is supported.

It's been enabled for quite some time, actually. Either way, yes. Sysmodules work.

I need to ask: is this applying layer to each frame independent or it works by different principle? I was thinking if this could be used to develop FPS Counter if it can detect each frame.

The problem is less the overlay than getting access to a game's framerate.
My layer and the game's update at different framerates (mine is actually 0, since it doesn't update unless its color should be changed).
Regarless of all that, the screen refreshes at 60Hz, which is independent from the actual game framerate (usually the game will sync with the screen's vsync).

Hope you could manage was to actually change the screen calibration it self instead of a filter rendered. Totally would love to give slightly more blue to the white balance on my screen but I would like it for the SX OS too

...

I will probably eventually move to atmosphere emunand when it's officially finished V1.0, but for now I just use SX OS and I barely use my switch anyway

Given that I don't think I will be adding anything worth releasing any time soon, I've decided to flush what I committed since last release.
So here is v1.1.1:

Massive improvement to sysmodule memory usage (nsp down 79% of previous size)
Made time sliders easier to control

Thanks!..
Can I make a lil' request — is there any way to autoboot the sysmodule / program and not to launch Fizeau homebrew by hand at every Switch boot?

It's possible, but seeing as the output binary is much larger (by 20+kib, ie a ~30% increase in size), I've decided that having to open the companion app after a reboot was a small enough inconvenience that is wasn't worth clogging the system memory pool.

Maybe you can do an option for that?..

Btw, thanks in advance.

Found this on reddit....

Unfortunately this doesn't filter out blue light (a la f.lux). This is a transparent overlay that adds orange to the screen.

Imagine a pixel has a RGB value of 100/150/150. A blue light filter would make this 100/150/20 (which appears more orange), whereas an overlay would make it 250/150/150 (which also appears more orange but still has the same amount of blue).

Is this true? If yes, might be best to properly explain that this doesn't reduce blue but instead adds additional coloring to the screen.

This would actually do the opposite of its intended effect as more color would likely keep you up, not put you to sleep. The study on page 2 indicating yellow/white light is more disruptive on sleep patterns is especially relevant considering this.

From the main post;

Overview:
Temperature/color:

Use the temperature slider to select the desired shading.

You can override the color by using the RGBA sliders.

The "Alpha" value controls the opacity of the layer.

Due to the way Fizeau works, it is sadly not possible to directly modify the screen color. Instead, it creates a transparent layer and applies color to it. However, this can lead to an overall increase of luminosity, especially visible with dark colors.

Additionally, the layer is not visible in screenshots/recordings.

Overlay makes it 250/150/150, you lower luminosity and end up with less blue light.
