Please show off what crt shaders can do!

Nope, I just tried it yesterday on the CRT and I think Retroarch does weird stuff. I found out that toggling drivers, D3D12 is slightly sharper than open GL, also toggling things like taking notifications off and power savings, does affect sharpness. I can tell the difference, even taking borderless off and leave exclusive full screen looks slightly better on a the CRT.

Seems odd this would be exclusive to a CRT, unless somehow he specific drivers/settings for it (e.g. switchres,emudriver) had an influence.

I would expect any sharpness changes to be more noticable on non-CRTs.

I’ve run into some issues with the Nivida driver and CRTs as second screen, where it’s necessary to make sure that no scaling is applied and scaling needs to be re-set to 1:1. But that’s a general issue, not RA releated.

I have no scaling, and I have it natively, games look awesome, I just don’t touch settings knowing now that Retroarch messes a bit with the image.

New presets available!

Now getting the hang of this miniLED with BFI thing.

Thank you! Can you tell, what presets are on those screenshots?

Those are just some of my latest Turbo Duo presets from my miniLED preset pack which I’ve been working on recently. The one with the animated movie is a Shadow Mask Preset from either the same pack or my W420M pack. It’s similar to the Genesis Composite Shadow Mask preset but I think I gave it an Alias with the word “Video” in it to help indicate that it’s suitability for video use as well.

Just sort the presets by Date Modified and you’ll see which are the newer ones.

Here are some more screenshots.

I wanted it to look like a CRT, like on the Astro City, but I think there’s still a lot of work to do.

I Know I’m almost there, but there’s something I can’t figure out what is missing… I’m still fighting to achieve what my new CRT looks like, I always find there’s half notch missing. I won’t stop until I’m satisfied. I know there’s still work to do.

Real Philips CRT.

My settings…

in real life the image looks clearer than the one on retroarch

Beforehand, we should test something like this. I also notice that Ryu’s colors are lighter on the TV than on RetroArch. That said, it’s just my personal opinion; we don’t all have the same screen, and that can vary from one screen to another.

I know, but it’s not only about that, it has to do with brightness, gamma, and contrast. I can make it sharper, but in some ways there’s something not matching, there’s something that I have to figure out, that looks blurrier than other settings, when I think I’ve got it, after a while I find there’s a notch I still can’t find what it is, and I haven’t yet found it yet. I know is not going to look like a real CRT, but I’m convinced that will look amazing if I find what it is. All I do is by eye, I don’t have any knowledge of image or photography.

You can notice that the sub-pixels are not visible in the image on the right, which removes part of the natural look that a real CRT screen provides. There’s also a loss of nuance in the colors and brightness, making the image less vibrant. To improve this, adjustments should be tested to make the pixel grid more apparent and simulate the sub-pixels as well as the physical structure of CRT screens. This could help recapture the realism and detail seen in the image on the left.

Yes, I know, that’s what I’m trying to do, but I don’t know which options I have to touch. I think that could be one of the reasons I still can’t find. Any Ideas?

Philips CRT screens, known for their marked brightness and slightly saturated colors, often used a slot mask or a fine dot mask, creating that effect of visible sub-pixels (red, green, blue). The scan lines of Philips CRTs were well-defined, especially in low resolution, often having a slight curvature and slightly blurry edges. They had a very fine mesh that gave the image a particular texture. These are the memories I have of my old television.

Increase the color saturation in the shader menu to make the colors more vibrant. Add a soft “bloom” effect to simulate light spilling slightly around bright colors.

Enable fine scanlines in the shader and adjust their intensity so they are visible without darkening the image too much. Activate the screen curvature option to mimic the curved effect of CRT screens.

Add subtle blur on the edges to simulate the limitations of a physical screen. The fine mesh pattern of Philips CRTs, in particular, gave the image a distinct texture. Adjust the pixel mesh or “mask strength” in the shader and experiment with different settings to achieve this tactile effect. After, I’m not an expert, I can only tell you what I know about this screen.

Which option is this? It would be easy if I know whick ine is it, I’m Using Guest NTSC advanced

We should check that with @guest.r

My recent presets including ntsc always include increased mask boost and lowered mask gamma.

Depending on which mask mitigation technique (bloom, mask bloom, halation…) is used it’s also worthwile to adjust the technique’s mask strength.

Halation is good for this, but might require to use fine bloom sampling at like 3.0. It’s also nice to tweak bloom pass settings for the effect height and width.

Imho it’s perfectly fine in terms of sharpness. If you increase it to much, it begs the question of what the difference to high TVL monitors is supposed to be in this regard.

The target display you’re using it on has presumably also a totally different size, affecting perception of the content.
