i bought a 20 eur amazon wonder, just because of the curiosity: https://www.amazon.de/dp/B0BW9MK247?psc=1&ref … product_details
the setup, what i used:
p3 with asus v6800 as source (not the best analogue output)
ossc for hdmi output
apple mba m1 with obs
what i really surprised:
* it could accept 70hz, and vga input directly
* if i choose the input resolution to 1080p, it shows the correct 4:3 image in the right position
* at 640x480 with the 320x240 content pixel perfect
what does not really good:
* it does not support too much resolution input profile, and if it does not matches to the real source resolution, it makes an internal scale - eg at 640x400 - stretched to 480p or 1080p
* the image is somehow darker
but anyway, for this price it is useful thingy. ok, it cannot make the datapath output quality, but does the job - and if they can do from a 20 eur "cable" a good scaling, why we do not have a cheap scaler on the market?
