Wondering if anyone has a good solution for getting a PC into the TBC2. So far, it seems like Startech DVI-VGA converter (p/n: DP2VGA2) I have doesnt produce a compatible resolution (2048x1280, 1920x1200 & 1080p at 60Hz). Probably should have checked that before getting the VGA expander… I tried forcing various resolutions and refresh rates with GPU driver but was not able to get a useable signal to TBC2. Seems like I should have gone with a component based converter instead.
Can’t help but laugh at myself for waiting a few years to then hit a wall so close to finish line because of a $20 converter!
Curious what kind of setups are working for you guys.
I don’t have my TBC2 yet, but am going to follow this thread to see if I can learn from it. Sorry I don’t have any wisdom to share. But in general my motto is ‘buy once, cry once’. I am going the component route, have Blackmagic Design UpDownCross converters and HDMI to Component converters. These are working well with a VU003B into the synth. I’m guessing that it will work just as well with a TBC2.
I’ve got two HDMI > component converter I was using before I switched the system over recently.
kramer vp 422 I believe and something generic from amazon ~$50 that worked just as well as the kramer from what I could tell.
With the switch over I’m using a BMD updowncross, a couple bidirectional SDI <> HDMI, and a HDMI > SDI
I forget which two boxes are dedicated to my two computer outputs
I use a m1 mac minis’ HDMI output and an appleTV running another desktop
then with the constellation switcher I have two bmd SDI > analog boxes, one for each channel of TBC2.
I haven’t gotten the TBC2 back in the mail yet to test but I am imagining this will work even more reliably than what I was using before.
I got a VGA expander when I ordered the TBC2 because that is how I was running my system at the time. Now I’m not really using VGA so it will probably just sit in a box for a while.
Just out of curiosity before I try anymore converters, is there anything that needs to be done to TBC2 aside from just plugging in ribbon cables to get the expander to work? I see there are a couple dip switches on the back. There doesn’t seem to be a full manual for Expander or TBC2 yet so I didn’t want to just start messing with stuff.
I tested out my current DP->VGA converter on a couple different monitors and it does seem to output supported resolutions and frequencies after all.
Forcing the resolutions in the Radeon driver does have quite a few technical options for the timing standards. Could the problem be from the wrong standard / settings?
Hi,
It was 1.01 but when I reset it said 1.01lc3 (I believe, or similar) Now it only says 1.01 again and it’s not working!
It is a bit sketchy, it would accept one straight up VGA signal (from Gieskes vga oscillator) It was fairly stable, though seemed to lose sync from time to time on a slow cycle.
When I tried it with an HDMI > VGA it’s not having it either.
A pity VGA is not working yet, composite out from the RPI is terribly noisy.
Interesting. The TBC2/ Expander doesn’t seem to like VGA converters. I unfortunately don’t have a native VGA source to check with. Hope the update comes soon!
I was using whatever the pi was set to, 720 I believe. However I don’t have an SDI to component converter.
Only HDMI to VGA, which even when pi is set to 1080 it won’t work.
If I recall correctly, the VGA expander was announced when HDMI features were removed from TBC2. Has the VGA + SCART Expander consistently worked for anyone?
I have another native VGA which does output 1080p I will have a go with this and see if VGA alone is possible again. I accidentally pressed reset firmware when the VGA was connected, and this was the time it worked. After another restart it won’t work with the device which was successful before.
I reset the firmware again to factory and it works with a native source but not an hdmi to vga converter.
Hopefully converter will be supported in later revisions.
I guess the adapter is waiting for some kind of EDID from a display (TBC2 in this case).
I think it’s worth trying something like this: https://www.amazon.es/EVanlak-passthrough-rearrange-splittersand-1920X1080/dp/B07YN42M1V
It will basically trick the HDMI-Adapter into believing that it is connected to a screen with some set resolution. Though, TBC2 should then be able to accept that resolution.
I tried again with another native vga device and the tbc2 could not recognise it. I tried some different resolution settings on the vga device but it did not work. Is there an outside range on tbc
