I have a question: How can I generate an image like the one on the left instead of the one on the right?

1. How is it when considering video output from actual consoles?
2. How is it when using emulators?

but to answer your question, that image is just a lower resolution LCD screen

And how is this called? CRT shader?

No, I mean about rendering the pixels like a grid. Like rendering the "subpixels" of the CRT. Is there something like it?

>> No.8347051

that grid is literally just a lower resolution LCD

On the off chance this isn't a troll, the image on the left is a Cathode Ray Tube or CRT television. If you've ever seen one of the big bulky old ones, or the huge boxy computer monitors, those are both CRTs. Because of how it displays pictures, blocky shapes tend to seem smoother and developers designed with this in mind - Look up the waterfall in Sonic the Hedgehog 1 as an example of a trick that only works on CRTs without help. This is why us and Generation X have such rose-tinted glasses for retro shit, because it really did look better back then.

You can achieve it by just getting a CRT - The brand I can recommend is Sony Trinitron, but they're hard to find and expensive nowadays even for desk models. Most people on this board will advocate for just grabbing any old CRT off the street of someone throwing it out, but that's not viable logistically at all. Note that games from the Seventh generation onwards are hit and miss on CRTs unless they're HD, which are in even shorter supply than regular ones.

For emulators, look up CRT Royale, but I hope you've got one hell of a rig, because the effect requires 4K if I recall correctly. I can't help you further, as I don't know how to configure it either.

it is not, that is quite clearly an LCD

Ah, thank you for the post. That was the information I was looking for.

The only difference is the colors are darker on the left. Fuck that shit. Just get a retrotink 5x and turn on the aperture grill, set the Pre-Emph to -3, set the filter to the notch filter and send the signal over composite. It's pure kino.

step back from your screen about 4 feet and they become the same image.

What's the point of this? Its not like the pixels are blending in a meaningful way like on the MD. CRTfags are so retarded.

That's not what sanic looks like on a CRT

Does that "blending" occur on an LCD when using composite?

Please stop posting this. It's an HD CRT. https://youtu.be/3PdMtwQQUmo
To answer OPs question, to make games look like that you either have to play them on a CRT (and that image is atypical of how the vast majority of CRTs look), or emulate and use shaders. Retroarch has a bunch, and Sonic Mania has an option in the menu to turn them on. I don't think there are any shaders specifically for emulating an HD CRT but likely you can get a similar effect by modifying something. I'd recommend CRT-Geom as a starting point: it's easy to run and has only a few options, unlike royale, which is much more advanced. The scale factor setting might approach the look you're after, not sure though. Have a play about.
