Acer Predator CG437K color calibration

JeroenJeroen North Bergen, NJ

Hello all,

I recently bought this monitor and am trying to figure out what the best calibration is.

I'd like to play my games in HDR (when possible) but noticed that (at least out of the box) the screen looks grayish and washed out when set to HDR mode in Windows 10.

I've tinkered with NVIDIA control settings and got it somewhat decent, but it is still not great.

My current settings are : 

Brightness:

Brightness 50 %

Contrast 87%

Gamma  1.10

Digital Vibrance  70%

Hue  0 degrees

 

I've read that Windows 10 HDR settings still don't work well and may want to consider going back to SDR.

Can anyone give me tips to make the screen look the best it can be?

 

Thank you,

 

Jeroen

  • What refresh rate are you currently running on the monitor? If you've "overclocked" it through the on-screen menu up to 144Hz, apparently that prevents you from using HDR and G-sync on this display. Also, the on-screen menu has an HDR setting you can enable or disable, have you checked that? It should be under the picture menu.

    Thank you for replying.
    I actually don't have the 144Hz function enabled. As you said, it prevents G-Sync and HDR. So now I am running at 3840*2160 (native) at 120Hz. I have turned on the HDR function on the monitor and also in Windows display setting. By default, it looked grayish and washed out a bit. I read about changing the NVIDIA control panel settings. (running a RTX 2080 Super). I've been tinkering with the settings above, but even though the screen is vibrant, the dark colors are not dark at all. I guess I've never really changed the default settings in Nvidia before as my previous monitors didn't really require it. 
    I know it's in the eye of the beholder, but what would you recommend that the settings should be in overall? Should I go to 144Hz and disregard HDR and G-Sync?

    These are all great questions. As you mentioned, this can be pretty subjective. Normally I would recommend looking at RTINGS for their settings with this panel, but it doesn't appear they've reviewed this model as of yet. That said, they do have their calibration guide available to help you calibrate with their downloaded patterns: https://www.rtings.com/monitor/learn/how-to-calibrate-your-monitor-settings

    Also keep in mind that when you tweak your settings, your ambient lighting will impact your viewing experience. A screen calibrated in a dark room will look dramatically different than a screen calibrated in a bright room and vice versa. I use an OLED TV for gaming, and I ended up calibrating multiple profiles, one for a dark room and one for a bright room, as the difference between the two can be staggering depending on the scene you are viewing.

    As for why your colors are washed out when enabling HDR, this is unfortunately a normal side effect of HDR. When you enable HDR, non-HDR content (SDR, standard sRGB, etc) are going to look washed out in comparison. It's only recommended to enable HDR when you are preparing to consume HDR content.

    Thank you TSMichaelB
    That makes sense, even though it sounds ridiculous on Microsoft's end.  You'd figure that they'd find a solution for that.  I will keep HDR turned off in Windows unless I will view HDR content. I guess games nowadays have settings to turn HDR on within games. 
    You're absolutely right about the ambient lighting. My computer is near a large window, which the sunlight would directly beam in the mornings. I like your idea to make a few profiles. Looks like this monitor can save these profiles. I'll give that a shot.

    I went to the Micro center store today and asked them about color calibration. They stated I should buy this color calibrator and download software for it. https://www.amazon.com/dp/B0055MBQOW?tag=georiot-us-default-20&th=1&psc=1&ascsubtag=dcw-us-6106266316775397000-20#ace-6003953244

    I don't know if it is worth to buy this unless one is a graphic designer or something. Wonder if there is an easier way. I will check out the RTINGS site you provided.

    Thanks again for your input.

    You're very welcome. I wouldn't recommend buying a color calibration tool unless you do work that requires extreme color accuracy. For the most part, you should be fine to eyeball it using the sample images available on RTINGS. As for the HDR issue with Windows, I agree entirely. I would imagine they could build a Windows theme around HDR content, and have it enable the moment you enable the HDR settings. This would force the desktop and settings to utilize HDR. The only issue with this idea is that there are still integrated Windows applications that wouldn't support HDR, and those would still look washed out in their individual application windows, but that would still be a far better compromise than the current solution. Hopefully we see better HDR support going forward, as I would like to utilize it more often on my OLED display as well. For gaming, it really is great technology.
