Scan lines on an LCD?

Obviously everyone prefers what they like but in some cases pixel blend made things effectively “higher resolution” than you get when you just have the pure pixels.

I’d not want to simulate a rf antenna either though. For me it’s about getting a good yet era appropriate picture not a bad era appropriate picture.

Indeed, that screen you linked to is with a consumer CRT using composite. The entire “PVM with $300 golden-plated RGB cables crafted by elves” thing is ridiculous. Nothing like that was available back in the day and no art was designed with it in mind.

The PVM outputs an image that is totally far from what was originally envisioned by game creators - almost as far as what an emulator outputs. There, I said it - I will wait for the PVM owners to come for me with the pitchforks and torches

I'll say it again... CRT FTW! lol

SCART (or Component as the SCART was more European / Japanese standard rather than USA) > S-video > Composite

I have been tempted to get a PVM but it goes from one extreme (pixelated glory on LCD/LED etc to over vivid scanlines) both of which are not how the games were originally designed.

Now back to searching for a 21" CRT...

when using BMC on my pi and an lcd I put the sharpness way down on the tv but also don't use point filtering so it's sufficiently blurry and then use scanlines or trinitron filter. This to me is pleasing especially as my real C64 was always played with rf and very nicely blurred. The C64 was quite blocky so the idea of it running on a monitor never appealed because of how sharp it would look. A different case though for Amiga I'd say

But you can tweak it with tons of different masks, scanlines, gamma, contrast, sharpness etc. The Retrotink 5x Pro scaler has similar advanced features. So, real machines pretty much look the same.

Sorry for raising an old-ish thread.
Can you change the aspect ratio using a Retrotink? I find some miggy games too squashed and like to stretch them vertically

Yes you can you can change the percentage separately horizontally and vertically. And save that into one of the profile slots to quickly change back and forth depending per game or Workbench.

I got one of the 1440p OLED gaming monitors that was recently launched.

I find these to be a perfect combo with the RetroTINK-5X as it can output 1440p@50Hz

As a bonus it supports HDR10 output. This was unexpected for me but HDR actually enhances the appearance of the scan lines and make the image more CRT-like if adjusting it properly. This together with OLED true black.

You can also enable VRR + Gen Lock and and that makes the input lag really low.

That's very handy. I assume any whd games run from within workbench would use the profile for workbench and you'd still have to tweak manually?

I'm using retroarch like this with my OLED using BFI, but I miss using real Amiga hardware. I'm thinking of getting an Amiga then buying the upcoming retrotink 4k for realistic scanlines. It's a big expense just to get the real Amiga feeling rather than P-UAE in retroarch, but when you get the itch you must scratch it. I could settle for a mister fpga and hide it inside an amiga style case. Close enough

Yes you have to use the remote to switch profiles manually.

Personally I always prefer a correct aspect ratio, rather than any kind of filling up the screen.

I'm certainly not filling the 16:9 display, I'm not a heathen
I just want to make some games less squashed vertically as is often the case with Amiga games, especially pc ports

[lesta_smsc]

CRT for scanlines... anything else is not really the same.

[dreadnought]

Scanlines are overrated. It's all about masks & grilles

I doubt anybody from my generation would even see the difference between a 1980s KVM domestic model vs PVM/BVMs, especially not via RGB analogue of an ST/Amiga/Megadrive/SNES if the CRT tubes are in like for like condition. Maybe with a microscope, maybe. The biggest problem is the smaller screen domestic TVs did not support S-video input.

Hard to find a good era Trinitron TV for a good price. I would like to have the exact same TV I played C64/Amiga/ST/Megadrive games on but it is becoming impossible to find in good condition at any price sadly.

If my friend hadn't junked his CRT tube rejuvenator............

My Sony Trinitron KV-14T1U had such a sharp and bright image with excellent geometry. One day it just went off whilst in use. Sad times...
