Spoiler

I'm wondering if the adapter isn't bidirectional? I figured on VGA Red is Red, Blue is Blue and all that, but maybe I'm missing something. I will check the pinout on it, maybe the Extron is expecting different pins to be used too.
Documentation makes it sound like it definitely wants something that looks like a sync pulse.maxtherabbit wrote:Extron auto switches on H-sync
If you're hell bent on using the auto switching, you might be able to trick it by putting a steady +5 or ground on VGA pin 13, but I doubt that will work. It probably requires an actual pulse waveform to trigger the auto switch
I don't think it would have anything other than those three lines going to the standard pins. Do you have anything else connected to the switch that may still be sending some signal and somehow keeping priority? My switch is an SW8 with two outputs, which may differ a bit from the ones with less inputs and a single output.bobrocks95 wrote:What's the setup on it, BNC female to VGA male?

The adapters are fairly cheap on HDFury's website, but I don't know what would make them work differently unless they're hiding additional circuitry.
Not really the case, since it actually switches even with just an audio line being detected--well, I wouldn't swear on this but I clearly remember this when I was routing audio from a Famicom to it while composite video was going elsewhere. The fact that it also switched for me with YPbPr also made me think that it will just switch with whatever it senses last.maxtherabbit wrote:Extron auto switches on H-sync
I suppose I could disconnect what's connected to the first input and see what happens. I have an SW12 with 2 outputs as well, so it should be functionally identical to yours, the SW8 and SW12 use the same manual as compared to the 2, 4, and 6 input versions.fernan1234 wrote:I don't think it would have anything other than those three lines going to the standard pins.

This is super dumb but you could run luma to a sync stripper (in addition to feeding it directly to VGA pin 2 of course) and then use the C-sync output from the stripper to trigger the switch.bobrocks95 wrote:Documentation makes it sound like it definitely wants something that looks like a sync pulse.maxtherabbit wrote:Extron auto switches on H-sync

No auto-switching completely kills the mood, I was thinking I could simplify my setup. Why would fernan1234's cable trigger auto-switching properly?

Ah, okay, this is the key detail that I didn't see when I was looking through. Mine's definitely not switching on audio, and definitely not switching on component, so HSync it is.maxtherabbit wrote:The docs also mention that using it for YPbPr will require manual switching
Yeah I've seen that behavior also. It's very infrequent and hard to pin down, but it seems to be somewhat dependent on the source device as to whether the auto switcher can handle the 15kHzmatt wrote:
Auto switching doesn't work for me. The unit doesn't seem to like 15khz csync and keeps shutting off the input sporadically. That's OK because I don't mind pushing the button.
Personally speaking I've since eliminated YPbPr from my setup completely. For quite awhile it was just the Wii for me, and now I've installed an ElectronAVE mod in it and run it and a few other consoles through an HDMI switch.smudgeface wrote: ↑Wed Jan 15, 2025 10:16 pm Joined this forum just to participate in this thread. Welcome all!
Did anyone ever get to the bottom of this? Maybe there's been some progress in the past 3 years?
If component video (YPbPr) on the VGA's RGB pins isn't enough to trigger the switching, did anyone try a sending one of the video signals (Y for example) down the HSync pin of the VGA? For example, get one of those RGBVH adapters on ebay and then use an RCA Y-adapter to connect the Y signal from your source device to both the G and the H pins on the VGA. Maybe that's enough?
