Viewing Photographs in Google Chrome makes Black Areas Pixelated Red

I have exactly the same problem on Chrome with my Eizo CX241. never found any solution for it.

I'm using Firefox and Edge with no problem at all. I just decided to uninstall chrome since FF is much better anyway

Thank you very much to you good folk for all your help.
I have a bit of paper from a University to say I am quite good at Marine Biology, but this does not cover computers and colour management!

I cannot seem to get to Hardware Acceleration settings from either of the descriptions that you and Dave have given.
Any chance you can give me a more detailed description of buttons to click?
Also, since talking about this to you, I deleted Kaspersky as I was advised to do and now rely on Microsoft's anti-virus.
Since doing this the pages in Google Chrome are tedious taking about a minute for each page to load.
No problem in Internet Explorer and Firefox, just Google Chrome.Another thing - in the other thread I recommended you set ColorNavigator to produce matrix profiles ("gamma value") instead of the default table-based (LUT) profiles. The latter are more complex and can be problematic. You have to do this each time you set up a new target.

Many thanks Daniel

I have downloaded Firefox as you said and do not have a problem with red pixels in this.
You mentioned in another thread that I should set it to COLOR MANAGEMENT MODE 1
May I kindly ask why? and how you do this? I didn't get far on Google!!!

Also, I know this was on another thread but you mentioned it here:

"in the other thread I recommended you set ColorNavigator to produce matrix profiles ("gamma value") instead of the default table-based (LUT) profiles. The latter are more complex and can be problematic. You have to do this each time you set up a new target."

May I kindly ask why use "Gamma Value" and not "LUT"?
It is just that ColorConfidence who sold me the monitor told me to keep it at LUT.
Tomorrow I will ask Eizo UK, but from the help you have been giving me, I very much value what you have to say and hence need more to take to them!

Many thanks Dag.

You can use the hardware acceleration for a system wide acceleration to your GPU, which will override anything you have set in your application. You can also have it set from within an application to have it do so internally. Except the Hardware acceleration within your system is not the same thing as it is within Chrome. Within the Operating System, it is to speed up processes computer wide, making the computer show better on benchmark tests, and work faster with imagery (mostly for gaming), but the acceleration can be used to make a box seem faster to help it sell better due to its higher benchmark numbers. But the hardware acceleration in Chrome doesn't effect images as much. It is used to speed up repetitive tasks the application may have to do because of your work habits and patterns and it essentially helps web pages render faster overall instead of just relying on your CPU to do it all. Yes, it can effect images on a site, but not so much with the colors as is seen here, but rather more in the resolution of the image in the end (sharp/soft/etc). And according to Google Chrome, when the issue seen here happens, they recommend checking on the operating system hardware acceleration as well. Those colors tend to mean your video card isn't functioning correctly, especially in combination with the hardware acceleration within the application. So turning off both is your best bet to help diagnose the issue. Then if you are not happy with how things are working at that time, turn them back on one at a time in order to diagnose any possible issue you may be creating

1. Choose Start > Control Panel.
2. Double-click Display.
3. Click the Settings tab.
4. Click Advanced.
5. Click the Troubleshoot tab.
6. Move the Hardware Acceleration slider to None.
7. Click Apply and then click OK to accept the new setting and close the dialog box.

That should get rid of the Hardware acceleration on the Operating system side of things. Probably a good idea to check to see if that is running or not since as you say the computer warranty is not going to happen since the company is no more. Hardware acceleration is hard on the computer and will cause things to die faster due to the added strain and heat caused with the acceleration. It may not be running on your computer, but it's pretty common for smaller companies to turn it on to try and make their computers seem faster/better than the hardware alone will allow.

If you want to turn it off in Chrome to see it it does anything (it probably won't since its there to accelerate repetitive actions), Just go to Chrome > Preferences > scroll down to Advanced Settings > Scroll Down to System > Turn off Hardware Acceleration.

Actually D Fosse, Hardware acceleration is primarily a system wide issue created to try and make a computer run faster, primarily in the GPU. Very common on gaming computers, and it will directly effect how images render. Yes, there is one in Google Chrome as well that tries to do something similar in that browser via their software. Both of those can effect image quality in the browser.

Hi Carl

What color space have you used for your photographs? I ask, as your screenshots have no embedded profile.

When exporting an image for web use, always convert it to sRGB color space and embed the color profile. Both Photoshop "Export As" and "Save for Web" will give you checkboxes to do that. That should ensure color consistency.

As for the GPU issues leading to those red marks, if you are using Windows then check the driver manufacturer for an updated GPU driver.

what kind of computer are you using and what operating system?

After looking, it almost looks like a color warning that the images dark areas are out of gamut or something. Do you have the latest version of Chrome installed? An older version may not be processing the image correctly. Also, is your computer using hardware acceleration? If so, turn that off and try to load the images again. That can make a difference as well...
