I have this monitor: http://www.overclockers.co.uk/showproduct.php?prodid=MO-025-AO&groupid=17&catid=1120

It's very nice, but I'm getting confused about something.

In my monitor research, I read about the nVidia/HDMI/limited RGB issues, so I have run the utility which makes the registry changes to force full RGB output.

I'm not sure if it's working correctly though, I've checked it using this image:

However I can see the individual squares more easily when I have my system set to limited range.

I can just see them when it's set to full range - it gets easier to see them if I turn the brightness and contrast right up.

When I have limited range set, all of the colours look slightly... "greyer", whereas when it's on full range, the colours are stronger, but blacks seem flatter (as per the test image I posted above).

Is this working correctly, or am I missing something?

Thanks!
 
Some monitors have an option in the OSD for the RGB range over HDMI. Its usually easy to tell as limited range patches of whiteish colours look "dusty" i.e. google home page.

It is working correctly. With limited range the first few squares should be more visible but the entire first row should have less distinction between shades. And importantly the background should be less of a deep black.

You can't use the DisplayPort instead?

My gfx card only has HDMI/DVI output =/

I did look through the OSD, but couldn't see any options for RGB range or anything like that.

Great, in that case it does sound like it's ok.

It does look better & more vibrant with full RGB set, I was clearly just looking at the test image wrong :p

Thanks guys :)
 
Haha, following on from this, I just realised by work BENQ GW2450 connected with HDMI was also running on limited RGB range.

Was wondering why a VA monitor was looking so washed out - forced the full range in the driver - boom! looks so much better now :D

First thing I did when I got my BenQ EW2440L AMVA panel last week was set it to full RGB on monitor settings and download the Nvidia full RGB software fix,then calibrate it via SpyderExpress after reboot.

Full RGB is better for obvious reasons,shame Nvidia have not sorted this issue out yet over HDMI.

How can you tell if it's limited rgb ?
