Hi again, I bought the adaptor and have been trying to make it work without success.

Since lemmon posted this, we've been testing different HDMI to VGA adapters, with success. Lemmon, thanks for helping me with the testing process. I'll post an article in Eiusdemmodi with our results.

[19/10/2018][CRT Emudriver 2.0][CRT Tools 2.0][beta 14]

  - [Emudriver]  Removed low pixel clock limitation on HDMI outputs. This allows outputting 15 kHz through HDMI in combination with HDMI->VGA active adapters.

  - [VMMaker]    Added support for EDID emulation on digital outputs (HDMI and DVI-D). EDID emulation drop-down menu now shows outputs by type. DisplayPort still not supported.

  - [VMMaker]    Support for pixelclocks up to 6 GHz. Modeline generation now possible from 15 kHz up to 8K fulldome. Bandwidth limitations imposed by drivers still apply.

  - [VMMaker]    Fix XML processing of newer versions of MAME.

  - [VMMaker]    Fix composite sync for HD 5000+ cards.

Long time since, but I bought one of these VGA to 4x BNC cables and have it connecting a 5450 directly via the VGA port (EDID emulation on, Composite sync on) to a Sony PVM

First of all would just like to thank calamity for the excellent CRT Emudriver 2.0. Got my Astro City with Nanao MS9-29 running on windows 7 with a Radeon HD 7790. It's all working great resolution switching etc.

I was hoping someone could help me figure out a problem I may have found with regards to colour accuracy. So since we all strive to achieve the closest we can to get these old games to look correct in terms of resolution and refresh rate, aspect ratio etc. I wanted to get the picture as good as i can. I have access to a x-rite eye 1 pro calibration device. I started to calibrate my monitor to get the best colour accuracy i could but came across a problem.

If you connect a pc to an arcade monitor via DVI-I to VGA the driver uses Full Range RGB values (0-255) automatically. The problem here is that on my setup blacks are crushed at the bottom end and whites are also destroyed at the top end. Confirmed using test patterns. I'm thinking i would need to change the pixel format via CCC to ycbcr or rgb limited 16-235. This would convert the full range signal in windows and send out the correct range for my monitor. (im assuming arcade monitors/crt tvs expect limited 16-235 range?)

So far i have tried installing various versions of CCC (i know it's not advised but wanted to try) but the pixel format option does not exist. I have also dug into the registry but could find no option to force it. I think the only way would be to overide the EDID or use a hdmi to vga adapter but i don't have access to one of these yet.

Sorry for the long winded post, i can't imagine the work gone into this project and don't want to sound like i'm complaining because i am not. I just strive for the perfect setup and was hoping someone could shed some light on any work arounds.

Thank you so much :-)

In this link there's a file named cnext64.7z, that's the standalone installer for the Radeon Settings app, corresponding to the Emudriver based on 16.2.

I doubt such setting exists, however.

MAME now supports LUT's for monitor calibration, check this. Unfortunately it's done through HLSL, which is undesired on CRTs. I don't know if you can disable HLSL feature but the LUT.

I downloaded and installed the cnext you linked but unfortunately the option is not there for pixel format. I read that it's not available when the connection detects a dvi output and just forces full RGB.

I appreciate the idea of the LUT but i was hoping to do a system wide calibration at monitor level using the pot adjustments so all my emulators look correct.

Do you think that if i ordered a hdmi to vga adaptor it would allow the options to appear?

I really appreciate the help and suggestion.
