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?

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.

Definitely the second one.
Looks clearer, there’s more contrast and definition. Also, when presets start off with a relatively softer foundation, things can easily get blurry when viewed from a distance, especially on larger screens.
Unless a CRT had an issue, they generally delivered the gaming goods without being blurry. Blur was never a thing not even the slightest amount, at least to me.
Then there’s the destruction of the mask that takes place the more we add artificial brightness, glow and blending/softening tricks.

Sorry to continue with final fight screenshots, but it is my reference.
I’ve just uploaded come new code to (hopefully) properly emulate dot matrix display.
I think this is the name for handheld consoles like gameboy, gamegear and so on, right?
This time ti grid alings to content pixels properly and rgb triads are drawn in every cell.
Of course the feature is not compatible with scanlines, or other, already in place, methods to draw rgb or mask triads, so if you want to try it, i suggest you to start from an all-off preset.
Oh, forget to use any kind of curvature, this is a not problem, since those screens were not curved, right?
Say yes please
Planned for the future is motion blur, but meanwhile i’d like to hear from you what do you think about it.
One complain is that unfortunately integer scaling with aspect correction plays verybad with it, so i’ve added another option to integer scaling to ignore aspect, but several games look really distorted.

Hello @kokoko3k. What is the preset for the handheld consoles you mention? I don’t see any new names in the shader pack.
On the other hand, version 4.0 of your shaders works great for me, with only the application of the general zoom I almost align the bezel with reflections with the thebezelproject (there is an edge left but I don’t care). Ideally, the bezel with reflections would be drawn on top of thebezelproject (regardless of size), but I don’t know if that can be done (and if it can, I don’t know how).
No preset yet, i’m still experimenting right now.
Still, if you download the development code, there is a new DOT matrix group you can play with, with a rudimentary motion blur too, but i repeat, it is in development.
@fenix76 (i always forget to press the reply to user button, damn)
As for images, you can choose if they are drawn on top or behind, depending on the alpha channel, but to draw the image on top, it has to be transparent via its alpha channel, as you can see in 1084s presets in koko-aio.
I don’t know if that’s the case btw.
As always, I strongly encourage to read docs.md (link in first post)

Gameboy emulation is shaping good imho:
Colors are from gambatte itself, no coloring done in shader.
The cell grid can be drawn in black or white (white in the screenshot ofc).
Motion blur/ghosting effect is in place, and one can choose if the ghost happens only on dark or bright pixels; i made this without really knowing how those dot matrix screens work.
Read: was the gameboy slow to draw black on white or slow to refresh the black to white?
Play with it.
In the screenshot you can see that there is that typical oblique shadow, i was implementing it, but then realized there is no need, since one can use the already in place deconvergenge y setting r,g and b to the same position (21,21,21 in the screenshot).
Rest of the wow effect is from vignette and spot, integer scaling used.
Edit-
There is now a gameboy preset on the development repo.

Little update. Now it is possible to emulate a monochrome display and selecting the hues for bright colors and dark colors; that way you can colorize the gameboy monochrome display by specifying the background color and the foreground one.
Also there is a new parameter to fadeout the dot matrix grid on the background (i remember that highering the contrast on the GB you were able to hide the grid)
As a side bonus, you can play super puzzle fighter 2 with gameboy colors and risk your eyes:
…or continue to risk your eyesight by using funky gameboy colors:
…still not sure if the color shift from one hue to the other has to happen in rgb or hsv space; mixing h from hsv could lead to weird results has you can see in the second shot, where actually there are three primary colors generated from just two of them; that could never happen in rgb.
