I just got this same adapter from AliExpress and on mine the part number of the chip is AG02-EX, they probably forget tho burn the number off ;) Here you have the datasheet of it mu.elecfans.net/201709/XR001%20VGA-VR1.0%20-.pdf
This adapter is NOT a line doubler or a scaler. It will only work if your TV is able to handle 15KHz on the HDMI. For some reason, most of my TVs have a wider frequency range on the HDMI port than on the VGA, while being processed by the same chip. If you can find your TV's full specs, look at the HDMI supported resolutions to see if 15KHz is supported!
Thanks for the tip. I've built the needed cables, and have yet to get any of my hardware to display with these devices. I'll have to look for a 15khz HDMI Monitor / TV
The problem is the ST’s lower resolution modes are 15khz 240p also known as half-field 480i or even field 480i, so I don’t know how you are supposed to upscale ST video signals, but my word would be to use stuff that can make a difference between 240p and 480i, as well as being able to display 480p and 80 columns.
What we cannot see on both of your videos is the cable you use to link the ST with the converter. Is it the ST to vga monochrome cable? I think no, it only tranfers mono video signal. Which cable did you use?
Hi @boyfromrivertown, I'm using the DIN13->VGA I built, pinout described on the previous video (ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-c25dlHFW584.html). Cheapest option is to build it, you can find the "Atari DIN 13" plug on eBay and the VGA connector almost anywhere. The only good off-the-shelf alternative I found is on coolnovelties (not affiliated, not tested but it seems it's the right one): coolnovelties.co.uk/coolnovelties/atari-st-video-cables/290-atari-st-to-vga-multi-sync-rgb-colour-monitor-cable.html Every other cable I could easily find on eBay are the Monochrome DIN->VGA, where the RGB are merged.
My personal preference? I would use a regular passthru VGA cable for Monochrome as is renders quite well, unless you really need to plug into HDMI. For color, the best I tried so far is the OSSC, but quite pricey. For a budget solution, depends if you monitor supports 15KHz over VGA or HDMI.
@@soloM81 At least that means it is able to handle the signal and its internal video processor will display something. Now how good is it doing it, results may vary but it's a good start, usually pretty good on all the ones I've tested. Unlike the CRT you won't see scanlines or flickering, and you may have a very small delay.
