Yes, pins 4 on both sides of the cable are connected together. And Pin 4 is NOT connected to GND (pin 5). Only pins 6, 7 & 9 are connected together.

I think, you hit the problem exactly !

I’m also thinking, something is “making the graphics card think the OSSC Pro is a monochrome device”

As I wrote before (#64810) it’s very strange, that:

A. the failure doesn’t occur doing warm boot (ctrl old delete) from a running system but

B. the failure does occur doing boot with the…Read more

ad #64814 concerning sampling phase, I tried out some “turn off AUTO” – but maybe you could tell me the exact OSSC Pro’s menu item, you mean ?

ad #64818 concerning VGA-cable & pins, I tested with circuit indicator/checker every pin-pair (from end to start of my cables) – especially pin 4 (ID2) with no issue found.

The only thing,…Read more

Yes, the same problems also happens with framelock turned OFF (60Hz, 50Hz, …)

 

p.s.: in the meanwhile I also found out, that the issue doesn’t occur (means colour is present correctly), in case of:

1. starting up my DOS machine as described in post #64799, followed by

2. computer “warm boot” (ctrl old delete) from the…Read more

If I need to enter BIOS I have to accept “monochrome like style”

It seems, my OSSC Pro is kind of sensitive for some “signals” out of the VGA connection from my ISA graphics (TSEN LABS ET4000) during running DOS boot process …

In the meanwhile, I found my problem solved by going this procedure:

1. connect my OSSC Pro as recommended to display and power supply – power OFF

2. let boot up my DOS machine COMPLETELY – without VGA connection to OSSC Pro !!!

3. after that – plug in VGA-cable to the OSSC Pro – then turn it ON

4. everything works in…Read more

I have to ask you for your expertise/help concerning colour problems with my new OSSC Pro using with my DOS PC (ISA graphics).

The problem is: to have no colours – only levels of gray/fawn – when booting up DOS (first catching my eyes the missing of the common yellow lettering of AMI BIO…Read more
