I imagine with a proper project board and more stable connections the quality would be better, but it suits my purposes. Well, it's not the greatest solution in the world, and from time to time I see some fuzziness. (Eventually I put it in a project box and used shorter wires to keep it neat.) So really, you just link up the similarly named pins, and when it comes to RGB pins you handle each color as an individual case of the above referenced circuit - EGA 0/LSB pin to the 1k resistor and 1/MSB pin to the 470 ohm resistor, joining both into the VGA pin for that color. Also, you can ignore the termination part as its not necessary as part of the circuit.

Here's a reference for the basic how to to convert the TTL signals to Analog: Īnother forum member, ejs suggested i use 1k and 470 ohm resistors as they are much more readily available, and it worked fine for me. So this is what the circuit actually does! First, here are VGA/EGA pinout references: You might even find one on your local craigslist. You can pick this model of monitor on ebay for under $40 shipped. Turns out, it also handles EGA's frequencies just fine! Please note that not every newer "multisync" branded monitor actually can support this. It's a standard vga/dvi monitor but does a good job of accepting a wide range of frequencies, such as the 15/24khz seen in Japanese retro PCs. My circuit does not fix this part - However, I already owned a NEC MultiSync 1970NX, a somewhat cheap LCD monitor from the early 2000s. Horizontal frequency mismatch (EGA scans at 15.7 and 21.8, VGA is 31.4) In EGA to VGA conversion there are basically there are two problems to solve:ġ. Let me note there are "EGA to VGA" converters all over the place on ebay but my understanding is they don't actually work for 21.8khz EGA frequencies and are more meant for certain arcade cabinets.

It wasn't very hard and I'm personally not great with electronics/hardware yet I was able to do it anyway. I ended up building an EGA to VGA adapter. I wanted to have support for an external display without purchasing an expensive EGA monitor.

I have a IBM 5155 PC with the ATI EGA Wonder driving an EGA signal to the internal monitor. S-Video/Composite Video output to 1440x900.Ĭolor Subcarrier Frequency: NTSC 3.579545 Mhz / PAL 4.433619 Mhz / PAL-M 3.57611 Mhz / PAL-N 3.582056 Mhz.ġ10 to 220 VAC at 50 or 60 Hz via AC adapter.Hey all, I think EGA is a subject most relevant to early PCs and clones so I thought it most appropriate to post here. Supports up to 1920x1200 video resolution. Supports world video systems including NTSC/PAL/SECAM TV.
