this is, in fact, the desktop image. The v-sync seems accurate (matches the height of my desktop image), but h-sync is off. maybe this is because the screens do have a max resolution of 640 x 480 and the adapter i'm using does output something different? Anyone an idea how to solve this? I'm stuck …

Why is it so important to use an HDMI-VGA converter? 🤷‍♂️ (...) wouldn't it be better to use the GPIO pins directly? good questions! few reasons: 1. didn't think that thats possible with GPIO pins so thats why i didn't check 2. if there's a simple adapter i could buy or fabricate with a few …

Thank you ryccardo. Sorry for slow answering, but I try to solve a lot of problems at the same time on this massive project with lots of moving parts, one of which is this beautiful display problem. I made some progress: Screenshot 2023-04-15 at 15.28.38.png this is, in fact, the desktop image. The …

@ryccardo thanks, i will try this. The VGA converter you are using is for DCC on two different pins and does not support this. So the question is: Is there a VGA converter that does support this? how can i find products that do? Most websites do not specify anything in detail on those converters. …

So I've tested this circuit with some success, but had troubles wiring the outgoing d-sub connector. First of all, my windows machine now detects the adapter as a VGA monitor and i can adjust the resolution, which made me happy. My MAC can't handle the adaptor thought (endless screen blanking), and …

All right, sorry for my slow answers. So the RCA scaler is out, got it. So for clarification, it's a mess in my head. The terminology is hard here. I would pass and look for something else - or just make it So by "it" you mean build a custom VGA EDID emulator dongle like that https://i.stack.imgur. …

I have found this product: Delock edid emulator vga - vga https://www.delock.de/produkt/63326/technische_details.html?setLanguage=en So with a default HDMI/VGA converter and this emulator I would circumvent the 15kHz/31kHz problem with my RCA scaler, or am I missing something? Problem with the B&W …

I see, I've come to the right place. Thanks so much for your answers. I'm out of my depth a little bit. So @Ryccardo you mean that if i build that small circuit myself, and work with a direct HDMI-VGA adapter, this could potentially work? Or is the EDID still needed? I'm building an enclosure as …

Hi all! I'm new to old hardware, but i have a project that initially seemed simple. But it isn't, at least for me. I have a IBM 8503 (Specs: http://ps-2.kev009.com/pcpartnerinfo/ctstips/5546.htm) and an "AMSTRAD" PC12MD . Both are monochrome displays and have a 7-pin D-Sub plug: IMG_20230315_123759. …
