Dell S2716DG 1440 144 Hz G-Sync Owners Thread - Page 179

strange the limited should almost remove all the lowest and highest colors.

Maybe redistributing the colors is the issue,

Can you set the monitor to limited as well(my BenQ has that as an option)? That would bring the black levels back down to where they should be.

I think it would help if I could find a way to force the nvidia driver to output 10bpc instead of 8 but I have no idea how to go about doing that.

Have you tried YCbCr444? It reduces banding on some monitors, probably by reducing the range of colors visible, but looks the same as rgb full to me.

Im not given any other options under output color format, simply RGB. I noticed something else that gives me both hope, and frustration. When I swap from limited color range back to full, the screen flashes once, the grey tint is gone, and grayscale looks perfect, then it flashes again, and the color banding comes back...

In fact what might be happening is that nvidia is applying dithering when colors are set to limited, but removes the dithering when set to full. I want dithering, but I don't want a gray cast on everything. There has to be some way to force the drivers to use dithering all the time with full range, but I have no idea how to force this.

This monitor has extremely few settings itself, and is missing that option.

Also just as a test, I tried connecting it to my onboard intel gpu with the original manufacturer's cable, and adjusting the gamma with intel's software, and it looks the same as with nvidia, so that was no help.

do you have a colorimeter? If not then using something like that is the only way to calibrate your screen properly. Otherwise you need to install a profile and hope that it looks good for your panel.
Look up the Dell on tft central they have a profile and a guide on how to install it there. There are also profiles scattered around in this thread.

You need to understand how calibration works. What you are probably getting is black crush which as the name suggests crushes the darker colours. Whilst this probably looks good it kills any detail. Read this guide below for a greater understanding on the subject. The Dell is an 8 bit panel it won't show 10 bit. 10 bit panels are expensive for a reason tongue.gif

I have a pretty good understanding of color calibration now. Reading this thread here:http://hardforum.com/showthread.php?t=1873362 It seems that the ATI/AMD driver software does calibration at the 10bit LUT level, then dithers to 8bit and looks perfect, whereas the nVidia software doesn't use any dithering. That's why I hold out some hope that forcing 10bit in the driver could fix the issue.

I guess limited range will not come to the rescue for this.

I have never found it to be useful, but many TV's use it so I am surprised the monitor can not use it(some people use the monitor for a TV after all).

The major issue with this monitor is the brightness, it just bombs your eyes as you are watching the sun for hours.
I have spent the day for reading this thread (180 pages) and many ppl have this issue.
A good advice from BrightShadow was to use this setting:
OST:
Colors set to Warm
Brightness 35 (mine is 25) Contrast 75

nVidia Control Panel:
Set gamma down to 0.61
Set digital vibrance to 55%



Also i i found when you enable the ULMB feature the screen becomes darker and it feel so better for browsing.(for white page)
I am testing ULMB ON:
OST:
Colors set to Standard
Brightness 50 Contrast 75
pulse width : 100

nVidia Control Panel:
Set gamma 0.80
Set digital vibrance to 50%
Brightness: 40/ Contrast: 37


Also using zoom at 125% on google chrome help a lot !!! i don t like to use the option on windows 10: Change the size of text, apps, and other items: 100% (Bump this up to 125 and i experienced blurry text.)
I will continue to search until i find a configuration for desktop and gaming then i could remove this headache when i use this LCD...mad.gif or i will have to return it mad.gif

So sad a so good gaming monitor is so bad for desktop use (web, word, etc..)
