How to fix darkness caused by crt shaders ? I want to play games with natural lighting whitout dark
If your monitor support HDR then activate that in Retroarch.

I am using phone, is there shader fix that?
Swipe your brightness slider to the right.

Unfortunately, this drains the battery and eye strain
Use a faster / lighter crt shader (for battery life) which usually come with a decent ammount of mask mitigation, in other words, masks, which usually lower overall brightness, are less strongly applied.
Most shaders also come with brightness adjusting parameters, but this canât overcome the actual screen brightness settings.

Cyberâs advice was not a joke.
If the screen is dark, what eye strain would you get by making it bright till natural by pushing your phoneâs brightness?
Also, probably your display is an (am)oled; this means that the power consumption does depend on the real light emitted, not by the brightness slider.

Thank you for Reply I am understanding now
I know Cyber donât mean a joke Thank you for information I meant that when I turn on the CRT shader, the image darkens about 40 percent. I just wanted to compensate for this percentage with a shader like bright boost dark boost etc.
Sorry for my bad English

Why?
Youâre gonna sacrifice quality by that way, thatâs why the preferred method on oled like screens is to push their brightness, I repeat: no added power consmption compared to the method of using the shader knobs.

Thanks, This is new info for me ,so i will swipe bright slider to right. I love libretro community

Other than doing this, you can use things like Bright Boost, Gamma Correction, adjusting Gamma In/Out, Post CRT Brightness, Bloom, Halation, Mask Strength, Glow however, most of these partners lower the accuracy and intensity of the CRT Mask and can lead to clipping of highlights if abused.
You can also use thicker or less opaque scanlines. This also has side effects.
What @kokoko3k said is true, in that youâre probably going to have a similar power usage increase by increasing those settings as opposed to just increasing the brightness of your screen if youâre using an AMOLED display.

Have you tried crt-hyllian? That one barely drops brightness compared to no shader.

Thank you I will try it
THANKS You are welcome Glow is look good for me My preset ntsc mini, simple color controls, glow. lottes mini has mask like my crt tv
I always learn a lot of things everyday on this forum

Even if you use a shader that doesnât âdrop brightnessâ, the effect on power consumption is going to be similar or the same as moving the brightness slider to the right.

Well, I figured it was worth recommending since hyllianâs light scanlines and aperture mask that it uses by default result in a bright image without having to crank brightness to compensate. hyllianâs shaders are also pretty lightweight performance wise.

Youâre not understanding. On an AMOLED screen white is white, bright is bright is bright and dark is dark. Dark uses less power, white and bright use more power regardless if this is achieved through brightening the screen by sliding the brightness control to the right or via the shader through accuracy compromises like âfake bloomâ and other stuff which adds white or activates extra subpixels on the display or decreases the saturation of the emulated phosphors or opacity of the scanline gaps.
In an âaccurateâ shader preset, the gaps between scanlines would generally be off as theyâre intended to simulate the areas on a CRT where the beam does not hit and energize the phosphors, on a less âaccurateâ preset the spaces that are supposed to be black might actually be a darker darker version of the colour of the raw pixels which would be displayed if no shader was used.
The latter might have a brighter image out of the box if the display isnât configured for âdisplay poweredâ presets but if it is then the net effect might be that both approaches might be consuming the same amount of power from the display.
âDisplay poweredâ shaders like Sony Megatron Color Video Monitor are inherently extremely lightweight because they donât use the GPU for all of those brightness and other enhancements.
Less GPU usage means less power consumption and longer battery life, not so?
Take a look at some photos of Sony Megatron Color Video Monitor to see what would be sacrificed by going with other methods. This is all subjective as to what everyone prefers though. Some like their CRT Shader presets to look good from a distance while others like them to look good all thr way up to the screen when they put their nose up to the screen.

I did mess with the Megatron shaders with HDR enabled on my LG C2 once, but it still looked way too dark even though I have the OLED brightness at 100 for HDR. I always end up preferring a lighter scanline effect when I feel like using a CRT shader, so stuff like hyllian or easymode-halation. I didnât know that Megatron was lightweight enough for Android portables though, thatâs neat. I thought it was more heavy on resources like Royal.
