Luckily a vga to hdmi convertor worked for that. Why have older style inputs if the dam tv wont except older resolutions that worked with those inputs?
Yeah, I hear ya. I found a really old RB thread discussing how, even back then when VGA was the PC standard, the DC VGA actually working on monitors was hit and miss. This baffled me a bit so dug in and found the following...
"When booted in VGA mode however, the DC outputs in the unusual 720x480p resolution, but only uses the inner 640x480p. Most 480p signals from other consoles and devices output in 640x480p which your TV is designed to display perfectly in 4:3 mode, but many modern TVs have not been designed with 720x480p [over VGA] in mind, meaning the image will appear squashed when set to 4:3 or stretched in widescreen mode, making the perfect aspect ratio unattainable."
I think that signal just confuses some TVs and monitors. We know it isn't a 15 vs 31 khz issue. You will absolutely run into that if trying to connect too old of a PC (or an arcade board) to modern monitor though. You have to specifically look for compatible sets. Bottom line, VGA compatibility is a crap shoot.
