Please show off what crt shaders can do!

Just for some additional context @anikom15 and @DariusG, this is the “TV” that I grew up with. From the 80’s straight through the 90’s and it was very sharp and clean through Composite. I wish I had known about the S-Video “mod” back in the day.

Late 90’s it developed some issues, then spent the last couple years under a table before finally being dumped at the side of the road long before we knew the real value of those things.

Yeah the commodore 1702, not a bad monitor at all. I still got my old 1084S-P1 on storage with a blown flyback.

The TVL figures given (for TVs usually from the marketed total linecount) are typically for the best signal type available.

There’s obviously going to be differences between CRTs of different time eras. Many years ago , I connected the Wii to the TV from a deceased family member. TV was probably from the middle of the 80s. I thought it looked ghastly, but I didn’t know half the things I know today, so I couldn’t make any significant adjustments.

The 1994-95 17" model I got a few years ago didn’t have that much worse composite compared to my newer 2000+ CRTs, but ofc these are not really Apple-Apple comparisons. The TV couldn’t do NTSC and was in worse condition compared to the ones I had.

Figures like TVL or the phosphor pitch are obviously also not the end of the story here. Interestingly, the 0.64mm pitch of the Commodore 1702 is still the same given for TVs of similar size 20 years later according to the CRT Database. I’m guessing this isn’t the part where significant jumps were made. As I stated in another post, the IBM monitor released for EGA equipped PCs in the early 80s also already had a pitch of 0.31mm. That isn’t much different from the 0.28 mm SVGA monitors 10 years later.

That being said, here’s a bunch of collected pics from older CRTs.

The Genesis has an extra soft composite signal. That is the major cause of blur in my screenshots.

If you do the math

1702 with 0.64mm: 440x330 resolution at 14"

1084S with 0.42mm: 660x500 resolution at 14"

That 1084S had insane TVL for the size. should be 500 TVL more or less. The Daewoo models (1084-SD) still got the same TVL. There is another Commodore monitor, the mutisync 1950 that got even more, 600

The TVL differences for the same tube get rarely documented, but there is some info available for 20" Ikegami/Panasonic models:

600 TVL

700 TVL

750 TVL

All for a tube which is supposed to be capable of 865 TVL.

Hey there,

This week I made my eyes bleed on some of the finest 90s motives I could find on the Megadrive. Funkedelic acid, face glued on the TV. How can something be so repulsive and yet so beautiful at the same time?

I’m sailing the Seas of Cheese!

With less de-converce, I wonder what this would look like. I like it the way it looks now but up close I see the de-convergence.

Hey there,

This week I bring here some pine trees for Christmas, as I planted quite a few on Alpha Centauri… Upscaled from 1360x768 to 4K with Gamescope/FSR and CRT-Guest-Advanced-HD’s slotmask and tweaks on top to bring some analog grain and break the squares. And the PRACX and Thinker community mods. So awesome to revisit that favourite of mine with those great shaders and improvements, thanks a lot! Here’s the .fx file if you want to test that in Reshade or VKBasalt.

Have a merry one guys and gals.

This is beautiful man! It would be nice to see a variation with a tiny bit less saturation, a little brighter Gamma, a little more sharpness and possibly a slighty cooler colour temperature.

Saturation from 1.20 to 1.10, temperature from 7200 to 7900, sharpness from 1.00 to 1.5 and gamma out from 0.5 to 0.41

Hey there,

Wish everyone here all the best for 26! This week I realised using Gnome on Linux there’s a built in scaler named “Fractionnal Scaling” in the settings that was messing things up when I used 4K.

It’s a fast scaler I started to use when I tried Wayland and had issues with GTK UIs. I left this naughty boy on and forgot it existed until recently when I tried to investigate issues I had with OBS and my 4K screenshots being way too soft in Lutris.

Turns out this fractional scaling, despite being set to 200% integer in 4K, was the culprit all along.

And I’ve been living in a 4K lie… Lesson’s learned, should always read the fine prints… XD

But the good thing is, now I got to go back and tweak all those shaders once again. And this time I’ll stuck my nose on the screen for good! At least I dont think that scaler was affecting Retroarch, which has its own fullscreen res setting.

So I’m back today with Heroes 3 Complete Edition, upscaled from 1066x600 to 4K with Scale2x and bilinear sharper from the great HD mod, gamescope/FSR and CRT-Guest-HD on top. Here’s the FX file if you want a go at it with Reshade or VKBasalt.

And here’s a close up showcasing the scalers, the mask and thin scanlines.

Hey there!

This week I tried 50 shades of Resident Evil… Gotta play them all eventually, even that version with clown fart sampled music…

Biohazard Mediakite + Classic REBirth / HDMod / SeamlessHDMediakite + Shaderglass & preset CRT-Guest

ROMHack RE True Director’s Cut on Swanstation / PGXP, 4X internal Res / Downsampling 240p / Shader CRT Scale2X+Newpixie

RE Deadly Silence (NDS) on Desmume or MelonDSDS / 4x internal res, hybrid screens / Shader aa4x+NDSColor+NewPixie

Side note, with the Desmume core I couldn’t solve the “blowing candle” puzzle, seems the sample used to emulate the mic wasn’t loud enough. Converted the save and got it working with MelonDS DS, but in turn the “spin the disc” puzzle wasnt working there (no audio) so I went back to Desmume.
