Sharp retrogame pixel

Hi guys, i record, above all, upscaled retroconsole, I’m trying to match 1:1 the quality that i see on preview screen, but even with best setting i can’t reach the same sharpness. I tried a lot of stuff but regarding the quality that something that doen’t seems to change, i didn’t find a way to have one pixel of clear solid color.
Input and Output are 1080p 60Fps.
Here’s an example of preview

The large scale waves look like a moire effect. Not an artifact from compression or upscaling. It is an interference phenomenon, often encountered with analog signals that are not pure. Is your console connected with an analog output? Check this signal path. May be different cable will help (longer or shorter, depends) or different layout of the cable (no tight circles, not near other cables), or the signal is too strong.

Or do you mean the slight ringing around the sharp edges? Especially at the black/purple transitions? This cannot be fully avoided - encoding algorithms aren't perfect, especially with these sharp edges. If the preview is ok, but the video not, it's the encoding. The moire effect seems to amplify these artifacts.
 
No i’m not talking about moire effect, unluckely the photo’s is compressed by imgur, original is too big to post, but you can yet see a lot of different shades of the same color in the second image. I have an high end setup so the ouput image (take from obs full screen output, first image) is almost crystal clear.
If not be fully avoided, have any suggestion to reduce it? The final results is still high level but i’m wondering if i can do a little better
 
If you're recording, you should record exactly the same resolution as your original source. There is no need for upscaling. If your retro console outputs a 640x480 signal, set your capture device, OBS canvas size and OBS output size all to 640x480. Let the media player do the upscaling while playing. But by upscaling, you're upscaling the noise and errors (such as the moire) as well. And upscaling will lose sharpness as well.
 
Sorry Koala but i've tried everything, and dedicated Upscaler and top cables for retrogame gave me the best result at the moment, i tried lower res also yesterday when i discovered this little problem (like i said, captures are great, i'm asking to understand if i can improve something) and the results were not near good. If you guys wants to take a look ask me in private i'm not here to promote my channel :)
 
You are right in theory but i think that my capture card (avermedia live gamer 4k) doesn’t handle signals under 1080p and apply a lot of shit upon it,. I‘m trying amarec right now and i reached completely lossless capture at cost of 4 seconds 170mb :D
