Getting your HDMI2VGA working with MiSTer

Unread post by zource »

(Nhee, you dont need IO board)

1.Settings needed:

edit /media/fat/mister.ini


2. You need a hdmi2vga with audio jack to get sound, external sound(usb) will not work with any core at this moment.

3. The best option is to use a active hdmi2vga with power inn (USB plug or power plug) and an audio jack.

4. If you already have a passive hdmi2vga (without power inn) with audio jack.

Then you may need to use a powered hdmi switch between(for boosting signal).

I gave this a shot for component video, built the adapter described here ... pr-signals, and tested 2 different hdmi->vga adapters (one from aliexpress, another from amazon) and had mixed results. The video was super bright (my crt was buzzing from the bloom), but blacks were washed out. I assumed this was from the adapter not being able to handle full hdmi, but the hdmi limited setting in mister doesn't seem to do anything for component. I was also a little worried about the signal being displaying on startup and switching cores, which my tv didn't seem to like. The amazon adapter was able to display everything I tested (just nes, snes, genesis, tg16, neogeo) but the aliexpress one wasn't able to handle a few of them and output a pretty bad looking signal. In the end I just didn't want to risk damaging my set. Might try again later on if I can get a decent external RGB-to-YPbPr converter, or will just cave and grab an IO board.

It's possible the adaptors you're using just aren't suitable for YPbPr, and that you need an external transcoder. Have you tried connecting to an RGB/VGA monitor just to make sure the RGB signal is OK?

I got a Ugreen adapter from Amazon, but I seem to have ground or sync issues with it when using with the DE-10 Nano, I get an image but it keeps drooping every 3-4 seconds. Now this only happens when using the DE-10's HDMI Output, it doesn't happen with other devices that output HDMI, any help?

This Ugreen was reported as working fine by other users, so the problem might be with your TV, or rather the combination of all three (MiSTer/Ugreen/TV). Some TVs seem to be sensitive to some MiSTer+I/O or adapter combos.
