Here is a shader that is aimed to replicate how an old CRT monitor would look, this method is currently used in most emulators eg: MAME, RetroArch, Snes9x, Project64...etc etc.
What can this shader do?
All the nice things a shader like this should have.

Could be better
It looks cool and works well, but I had some scaling issues, especially in full-screen. Maybe add a bit of code to auto adjust to the window size?
Also it seems like a weird thing to not respond to anyone, kinda the opposite of what you should be going for. Anyone who has issues won't really be able to get help.
The asset is provided for FREE, I've made it clear there is no support. If you have issues with this, then don't use it. As the old saying goes: "you get what you paid for".
There are other CRT shaders available on the Marketplace, spend your money on them and get support or learn how this FREEEEEE one works and fix it yourself.
The shader code is OLD and I have no intention to ever update or change it.
Amazing
This CRT is almost as good as I hoped for.
I only wish there was an easy way to adjust the scanlines, (and maybe a little color bleed)
great, but the formatting sucks
Great shader
You should add highp qualifier to the line 58 of your shader.
On iOS shader is producing artifacts without it.
So the line should be:
highp vec4 coeffs = PI * vec4(1.0 + uv_ratio.x, uv_ratio.x, 1.0 - uv_ratio.x, 2.0 - uv_ratio.x);
Doesn't scale great with fullscreen
I had to add a line of code in the shader object to set its scale variable relative to the size of the screen to get fullscreen to work at all for my project (it would just place the screen in the corner of my monitor) but even then it ended up looking very different from windowed mode. Better, but different enough that I can't trust that it will look good to all players (those in windowed mode get a worse experience, for example).
Works Great
Works perfectly and does what you would expect.
Wonderful!
This just went into my toolbox. Does what it does well. Thank you for this.
bad
Awesome
Made by the best shader coder out there!
Nice
Good. But does't seens to work with views and fullscreen.
Great!
It's a really good system.
One thing I need help with is scaling with views and fullscreen.
Superb!
This shader was really easy to implement in my current project. I will probably tweak it a little but overall the effect is really nice. I would happily have paid for this shader, getting it for free is amazing, thanks! :)
Excellent
Easy to use and greats a very realistic effect.
With a bit of tweaking I was able to get the right look I was looking for.
Great Shader
Great shader, but I get a weird circular distortion around the middle of the screen that's hard to ignore with a black background. Might just be how I implemented it though. (Or maybe that's how it's suppose to be)
Oh and btw I like your vignette & noise shader. I think it'd be cool if you made a shader that combined the screen distortion from this shader with the noise from the other.
Fullscreen and views?
Does it work with fullscreen and views?
Great, but could use adjustments
The filter is great and I'm going to use it on my game. I wish I could adjust the intensity of the scanlines effect. It's too much, I wish it was 30% of that. I have tried to change the code but I couldn't reach that effect.
Very usefull !
I like it but i can't use it untill i found how to delete the line effet i'm just looking for distortion :/
But nice job !
EDIT: Thanks, this update is perfect, 5 stars !

Version 1.0.2 - Added a shader that only does distortion and borders, no scanlines.
Perfect nostalgia
Provides perfect retro effect for your game!

Thanks, I've fixed this issue now

not bad, but..
is it possible to remove only stripes?

works very nice!
I have a section in my game that I want to look like a CRT monitor and this is perfect!

Looks good, but might take a bit to use
I had to learn how to draw text while this is enabled. Be sure to devote a little time to it.

A must for retro projects. Excellent work.

An essential shader for retro-game projects. :)
Does a fantastic job at mimicking the old CRT screens and was extremely easy to incorporate into all my retro projects and configure it to the player's tastes. Recommended! :)

Viewtiful!
I love all xygthop3 works with shaders, but this one is probably my favorite one, to the point i decided to use it in my game. The most beautiful flowing water i could find around!

Love the effects available - good fun playing around with the settings.
Could maybe use a few more comments here and there but for free it's great.
