Hi folks,

Hope someone here can help.

I picked up an Iiyama Vison Master Pro 455. It's a lovely monitor and in great condition.

I have a bit of a weird issue though. I get severely crushed blacks when connecting it to my pc via a HDMI to VGA adapter. In the Nvidia Control panel if I shift it to RGB limited, everything looks correct. I currently don't have a direct VGA device so am forced to use the adapter.

The reason I query this is because as I understood it, monitors used RGB Full? I'm just wondering why I need to set it to limited to see the image properly.

Thank you.

Could be the HDMI adapter outputting that way, rather than the monitor itself.

Try connecting it to something through just a VGA cable... see if it is the monitor or the HDMI adapter.

Okay will do, my current retro PC is disassembled as I was going to get it recapped. I'm hopeful it's just the adapter doing it. I have an OSSC which if I set to output in YCbCr, it works perfectly. Must be the way the adapter handles the signal.
