I stumbled upon this same mask a while back. It’s surprising how well it works at couch mode distances, but lacks subtlety up close. It’s a decent option for 1080p.

Is it possible in the latest version to align corner reflections with the conversion point of the overlay’s edges?
soqueroeu pointed that mega bezel can do that:
It would be especially useful in case there were too many textures to redo.

Nope, I already explained the reason in the past:
While I use a pre-generated png for the monitor frame, Mega Bezel generates the whole thing at runtime, so it is more versatile ad adaptable via parameters than koko-aio.

Hi Kokoko3k, I wanted to thank you again for your work. I use your shaders on a regular basis with RetroArch on smartphones with surprising results in terms of quality and performance. I have a Poco M4 Pro, and of course I use a joypad (you hate touch controls in these contexts). These are shots using your tv-aperturegrille-bloom-bezelwider preset with very small tweaks (I brought the gamma out to 55 and turned off the BRG deconvergence for darker colors and better sharpness. Thanks again.

Small side note: doing this post, since it wasn’t recognizable from the screen, I saw that on that preset keeping the RGB deconvergence active improves the smoothing of things, as you can see from the screenshot of the Shinobi III screen, so I think I’ll keep just that change to the gamma out (the smartphone has an OLED screen, the colors are stronger than average) Thanks again for your work.
Very subtle, but yes, it is expected to apply some kind of blur.

I finally got to try the latest release, but it seems that you adjusted some default parameters that I was counting on in my custom presets, since I didn’t think I would need to override them in case of such future changes, this is the first change I found so far:
The Red, Green, Blue values were at -0.30 or -0.50 I don’t remember.
I will redo all presets.
Yeah, i slightly changed them, sorry 
…at least you can override with ease, keep up the good work!

Hi. Small bug in ver4 - there is a faint black vertical line on the left and right side of the screen - should be easy to spot on a game with a white background (sonic etc) using any of the TV settings.
@oldpainless Weird, I tested all of the presets before release. Could you send me a screenshot please?
You can see them on the left and right hand side (1080p output).
Thanks, I cannot see on my side, damn… I see you are using an overlay there, i’m I right? What if you don’t use it?
I’ll check, but no problems with the previous version (using the Bezel Project pack).
EDIT - still there with overlay off.
Yes, but I need to replicate the issue to be able to fix it, so we need to use the same configuration. btw I don’t know about the bezel project pack, so if the issue is not present without that overlay, could you please tell me how to use the exact same configuration?
tv-aperturegrille-bloom-bezelwider.slangp
Output 1080p. Vulkan. Issue present in Mame, FBAneo, Genesis Plus GX wide etc etc
Any other info you need from me?
Sent you a pm so that we can discuss there.

Sent you another PM.
I was looking to an old post here and noticed that somehow the look of my preset has deviated from the one I intended at first.
This was from a post of mine from months ago:
At the time, I really liked the sharpness and it gave me the impression of a real CRT when watching my LCD monitor.
By the way it seems, i kinda lost the sight, it may be highly subjective ofc, that is why i’d like to ask you all.
This is how the monitor presets look more or less now:
This is how i eventually will turn them into, please see at 100% zoom, since the colors when scaled are really messed up:
What do you prefer, i really can’t decide

They both look sexy to be honest lol. Hard to choose but just off shots alone I would probably go with the first one, looks more “bloomy” and I love my bloom. I’d have to try the second one out first hand to get a better feel for it.
I’m kind of in a similar state as you right now, I wanna switch things up a bit with my presets, only difference is I don’t have a set goal to what I even want. Maybe I should start looking at some high quality crt pics for inspiration.
