NZXT Signal 4K30 Green Tint Issue

Hi everyone,

I’m having a weird issue with my NZXT Signal 4K30 capture card.
When I connect older GPUs, the image has a green tint, even in the BIOS.
With the NZXT Signal HD60, everything looks fine.

Tested GPUs:
• Radeon HD 6670 → Green tint in BIOS, normal in OS
• GTX 560 Ti → Green tint in BIOS and OS
• GTX 970 → Green on one system, fine on another
• RX 7900 XTX → Works perfectly

Systems:
• Asus P8Z68-V LX + i7-2700K
• MSI MAG Tomahawk WiFi + i5-13600K

If I convert the HDMI signal to VGA and back to HDMI, the green tint disappears, which makes me think it’s some kind of EDID or color-space issue.

Has anyone seen this before or found a reliable fix?
Would an EDID emulator or HDMI splitter with EDID management help here?

Thanks in advance for any advice!
