HDMI to Component (for old JVC CRT TV)

Unread post by eightbit »

So this weekend I scored a pretty nice working 32inch JVC CRT TV circa 2003. It has component connections which I have tested with a component ready DVD player and the picture looks great.

Now time to get my MiSTer to it. I am aware of the ini settings that will need to be changed, not a problem. But I am curious as to what adapter or cable to buy. I have the digital IO board that does NOT have the VGA port, so I must use the DE10-NANO's HDMI for direct video....which I hear is not a problem.

I was looking at this adapter:

https://www.amazon.com/gp/product/B07PM ... XLVF&psc=1

Will this work? Or does anyone have another recommendation that they have tested working fine for HDMI to Component to an old TV?

Any help is appreciated!

Wiki says to use HDMI-VGA converter, not HDMI-Component. Maybe it will work, but I personally wouldn't risk it.

When looking for my HDMI-VGA DAC I typed in the search the name of the recommended chip - AG6200...just to be on the safe side.

Then you'll need an appropriately modded cable, check the wiki for details.

I use the I/O board for component output but on a whim I tried out the following HDMI to Component adapter:
https://www.amazon.com/gp/product/B082HT11MH

It displays a picture but the colors are off, kind of greenish. With ypbpr settings on ini to 0, it gives better colors but I get a rolling picture.

Have you tried flipping the SOG switch?

The SOG switch is for the I/O board. I was testing direct_video via the HDMI output.

Gotcha. Probably the same issue though. When using a VGA adapter, you have to do a mod to the adapter to enable SoG through it, so you might need to do something similar for the component cable.

I went ahead and ordered that adapter I linked in the beginning of this thread and it is supposed to arrive tomorrow. No skin off my nose if it does not work as I can always return it. I am just curious to see if it actually works. I will update with my results.


EDIT: And, it didn't work ;) I didn't expect it to and have the Rankie HDMI to VGA on order along with VGA to component cable, but I was curious and wanted to see what happens. Well, now we all know ;)

I ordered this:

https://www.amazon.com/gp/product/B00ZM ... UTF8&psc=1

and this (as a comment in the reviews from someone specifically called out that it worked with the MiSTer....more people should do that!):

https://www.amazon.com/gp/product/B07F3 ... UTF8&psc=1


I am fairly certain this combo will work as I have seen many reported that the Rankie adapter is compatible. I spent a lot of time in forum threads before ordering these as I want to make sure I get it right and move on with using this on a CRT. Pretty excited about that!

I have those same exact items for my Mister. The HDMI to VGA adapter I use for hooking up to a Dell 2001fp monitor and the cable I use for my I/O board to go to a Component input on a TV. Hope you can get the combination to work for HDMI-Component.

I still think it would be great if the Analogue DAC signal spec was opened up so that other devices (MiSTer?) could support it.
