Probably no way to find the previous version. Have you got a backup

I just restored them from a backup I made in Franco's app, but you can also use Arstoien's app which lets you directly set VisceralPsyche's settings (plus a few others like Halfbreed), though you have to manually do the RGB values to 175 yourself.

Edit: Also note that if you manually force Visceral's settings, the Franco app will crash at the gamma selection screen unless you reset them to default. Just something to be aware of.

Edit 2: Here is an updated version with full gamma/RGB control (though without the presets).

Franco thanks for listening my problem and added the hotplug settings on boot in 8.8. Much appreciated.

My observations with Display Tester on Obsanity, Kel Ghu and Visceralpsyche's (1st version, not currently compatible until properly matched to the new values) settings, all on brightness 50% and their respective recommended rgb values:

average:
Obsanity: 2.17
Kel Ghu: 2.3
Visceralpsyche: 1.99

detailed (Obsanity / Kel Ghu / Visceralpsyche):
2.4 / 2.6 / 2.2 – grey
2.0 / 2.1 / 1.8 – red
2.1 / 2.2 / 2.0 – green
2.1 / 2.2 / 1.8 – blue
2.3 / 2.4 / 2.2 – yellow
2.3 / 2.4 / 2.1 – cyan
2.2 / 2.2 / 1.8 – magenta
little colour banding issues / slightly less banding / no banding issues

Thanks. It looks like you have the same screen as mine. But your screen responds differently to settings. I get 1.7 gamma for RGB with Obsanity's setting.

Screen count is still 3, but we have something new. Screen response to settings are also different (in-unit variation) it seems.

I only calibrate RGB gamma, because they are the pixels on our screens and the only relevant gamma. The other ones are not important in the sense that we have no control over them and yellow, cyan and magenta being the results of the mix of RGB 2 by 2. Do only the average of RGB if you have to do it.

Franco, do you plan on doing gamma for each color channel like Faux? I don't need it, but it looks like some people could use it.

VisceralPsyche will probably give us new settings based on the new value limits.

The screen count so far is 3.

I'm guessing that I'm in the same boat as them. I'm getting similar values. Altho' some are close to 2.3. But most of them are around 2.4/2.6. This is with your and obsanity's settings.
I'm hoping someone will figure out the correct values for our type of screens

In additional, whenever I check the CPU, just 2 cores in using, I dont know when I play game or running heavy apps, 2 others run or not? Thanks

If you don't know what it is do not mess with it. Leave it as it is. Franco changed it for a reason. You can download a app called "perfmon" from the play store to see if the CPU cores are running.

Hi Franco, does it mean I don't need to back up any kernel setting that I configured in your updater app before flashing newer kernel but still can preserve the previous setting?

I noticed that on the new kernel app, the sliders are awesome but.

I can no longer set values beyond 255.
It also won't let me enter the value of "12". It slides to "23"

My previous gamma values were:

Grays 0
Mids 255
Blacks 255
Contrast 0
Brightness 0
Saturation 7
Whites 12

The new slider app won't let me enter these anymore as they were very awesome.
Is there a way to roll back to 8.7.1?
