Suggestions for using the TBC2 with a PC

Please see this thread for a recent update:

TBC2 has been released!

Hi TBC2 crew – just wanted to update you. I just received revised boards for some production changes on TBC2 that were necessary for batch #2, and expect to be back to the software related fixes next week. I want to at least get 1.0.2 out in the short term. For batch #2 we will be moving to a Gen3 style front panel design. There will be some update kits (frontpanel + standoffs/screws) available for anyone who wants to change their Orion era assemblies. We’ll keep the price close to costs on …

Firmware 1.0.1 is out now, and only includes a couple of quick fixes.
Firmware 1.0.2 is next, and includes some fixes for VGA input detection and any other bugfixes.
Firmware 1.1.0 will be after that, and includes any new feature adds (Component proc amp, Screensaver, etc.)

All of these features have been implemented (some I was planning to make part of 1.0.1), but there have been some new bugs I introduced while adding them, so that’s what’s keeping me from a quick release. I am prioritizing finishing assemblies and shipping orders to those who don’t have the module yet, but am getting close to being caught up. So hang tight, please try to enjoy the initial release firmware, and we’ll have updates soon.

This recent update from 38 days ago on Apr 5, 2023 is the only mention of VGA in thread. Does ‘some fixes’ imply that the VGA + SCART Expander is not currently working?

As mentioned up thread, you can get video into VGA/SCART in HD/SD video formats without problem. VESA input support (640x480, 800x600 and 1024x768) is what will be added in firmware version 1.0.2. Does this answer your question? What device are you currently trying to use?

Thanks for linking this, I had missed it. I have had some success with the vga but it is a little inconsistent at the moment.

I had success with the Gieskes VGA oscillator, at I think 600x480 (or whatever classic VGA is)

I tried with a VGA output at 1920x1080 from my video converter feedback device. This was not recognised.

Normally I use a VGA to video converter on the VGA output of the feedback device so I know it is outputting a stable signal, it’s more stable than the composite output : )

I don’t know about any of that VGA stuff, expander stuff, etc.

But the best way to get the full range of possibilities for PC → LZX is:

1. Set PC output to a proper broadcast standard. E.g. 1920x1080 interlaced @ 59.94 Hz.

2. Convert HDMI to YPbPr, plug into decoder RCA inputs. Note that DisplayPort and DVI outputs should be able to connect directly to an HDMI input with passive adapter or cable.

I am using a fairly expensive broadcast switcher to do the D → A conversion, and my decoder is the Syntonie VU003B, but the basic concept is the same.

I use the best buy insignia brand HDMI to NTSC (RCA) composite converter. That’s how i go from PC into visual cortex. I get full color by converting the composite to component. Not the most elegant solution, but I like it.
