Please show off what crt shaders can do!

[Electrode]

I see. It would be much easier for me to make adjustments if I had a consumer-level CRT TV with me lol (I do have a CRT but it is a Philips Magnavox 27MS5402, which is an HD CRT with Progressive Scan support via component). Then I could make adjustments on the fly to see how I can make low TVL look better.

I just can’t seem to get Mask 8 to look right on my end. It just looks funky at times. I will have to experiment more, could be my monitor. Though I did mess around with Mask #6 and by turning down the Mask Strength to .60 and the Low Strength to .70, it makes it look very nice. It has a very consumer TV look.

I want to also show what it looks like with pixel art games such as Streets of Rage, but the Genesis Plus GX core isn’t letting me take good screenshots. They always come out like this.

Anyway, here are the settings. Feel free to adjust Grade levels as desired (tried to put it in a quote without the shader preset being a whole wall of text; not sure how to do it lol).

That looks really interesting with that game, though it’d be interesting to see that chain on dark souls or bloodborne, I think that it would add to the atmosphere tbh.

Two of my best games,I’m waiting for Elden Ring.

To be fair, mask 8 is a very coarse mask, it’s 270 TVL (at 1080p) which is like a 14" - 19" TV. Scanlines on such a TV are much less visible because the beam focus was the same as on a larger set, but the mask is smaller. Tighter beam focus would have increased the cost of these smaller TVs.

For mask 8 I recommend reduced scanline strength and some additional blur.

Then again, it’s also very subpixel-dependent. The subpixel-respecting masks are likely going to look pretty weird if you don’t have the right subpixels. The BW masks are probably your best option.

Here are my custom files from CRT-Royale and NTSC shaders.

My goal was to obtain the clearest, most colorful, sharp image possible as well as the maximum input gamma without loss of detail.

The same goes for the transparency effects that I added. I removed anything that was unnecessary to make the shader lighter.

Copy paste everything in you shader directory. For GL_Core and Vulkan.

Very cool, I like the ambiance and organic feel this is adding

Current progress on a pro monitor setup using the new Guest-Dr-Venom.

Here’s what I’m using as a reference. Obviously it’s going to be impossible to replicate this level of detail at 1080p, just trying to get as close as possible.

Is this one of the Royale presets posted by ProfessorBraun?

[CybeREX]

No, this is custom presets by me with your hyllian-glow-new shader. I will post settings when came to home.

[Hyllian]

Oh, didn’t recognize my own filter. Lol. That mask is great. I tend to like trinitron masks more than any other.

In my region there was an auction with dozens of Sony TV Trinitron (New ones, never unboxed) and they are selling them on “ebays”-like here. I’m thinking about buying a 21" one, fabricated between 2007 and 2008. They’re asking some 100 Bucks for those. Link: https://youtu.be/HONCktzSzD8

Do you have any experience about comparing real crt with the most advanced crt shaders? In stills they look very similar. My question is more about how they compare in movement.

[Nesguy]

It doesn’t look like that on a plasma at all, though

Plasma looks best with just scanlines IMO.

In motion, all mask detail is going to disappear completely unless you have black frame insertion activated, and even that might not be enough on some displays in my experience.

[DevilSingh]

Tried my hand at taking a photo of my monitor!

Nice! If you zoom in further you should be able to see RGB phosphors/subpixels for an even more accurate shot, but this requires something close to 100% mask strength.

It’s also nice if you can get the very bright phosphors to bleed over the black lines but this is hard to do. I feel like the Secret of Mana shot I posted is nailing this, wish I could remember what settings I used.

There are a lot of intangibles that break the illusion. I don’t have any emissive flat-panels (like OLED), but that might help with some of it. Having a thick piece of glass in front to handle the internal reflection/haloing would be good, too.

And, of course, the quality of the motion and natural glow-trails are very hard (read: impossible) to fake well at 60 Hz.

[Electrode]

I agree with hunterk. In fact, having a higher refresh-rate LCD monitor can help immensely with getting movement closer to that of a CRT. My 1440p monitor is a 144Hz G-SYNC monitor and if I enable G-SYNC and set the Vertical Swap to 2, it does help mitigate ghosting quite a bit and helps in trying to preserve fluid motion like in CRTs.
