Iiyama GB3466WQSU-B1 Curve (1500R) 34” 1440 144Hz VA panel FreeSync Premium Pro

A wee update. While I see no flickering when playing games on my 5700xt, I do see some very slight flickering (barely noticeable) when I work remotely with very dark background terminals over Citrix, I think this is it all comes down and is inherent aspect of Citrix streaming from my work which transmits a very low flow of frames, anything between 5 to max 30 frames per second (for obvious reasons). As I said, flickering with Citrix is so low that I don't think it's atually an issue, or that I'd ever notice it if I was unaware of the heavy flickering with the previous firmware.
 
Did you change anything in the picture settings/colours? If so, could you post them please? :)

I got mine back today from Iiyama according to the tracking and I am very excited.
 
Haven't changed much really as I profile my monitors using my wife's Xrite display profiler (she works with Lightroom on a AdoberRGB gamut monitor and needs accurate colours representation when adjusting photos). So nice thing with a display profiler is it does all colour adjustments for you and trust me it makes so much difference. The only thing I changed is I decreased brightness and enabled freesync. I've kept overdrive and MBR and their deafults.
 
Waiting for this to come back in stock as well, does anyone know if the new ones will come shipped with the updated firmware? I'm going to assume so as their doesn't seem to be any old stock anywhere available.

I'm also gonna be running this with an Nvidia gpu RTX 2080 so hopefully won't see the flickering issue while running freesync (if its compatible).

Does the Display Profiler create an ICC profile? Would you share this with us? :) Or does it not make sense?

Yep no probs, I can do that but bear in mind these profiles are based on the current ambient light conditions, that is, how much light and what sort of light is in the room. I'll re-profile it in decent light conditions and make ICC available.
 
My pleasure. I wonder if the profile reproduces the colours the same way it does with my monitor. Physically both mine and yours are the same VA panels so there should be no surprises. One important thing I forgot to mention and could affect the result is both profiles were created at brightness set to 35% and contrast at 50%. If you'd like me to prepare them for your chosen brightness/contrast configuration just let me know.

I briefly installed the profile yesterday when I rebuilt the monitor after the RMA. At first sight it looks really good and much better than the standard profile which was assigned. This one was rather yellowish.

I will try out your brightness and contrast values this evening :) Thanks for the info. If it's not too much effort for you, a profile with 50% brightness would be great :)

The color temperature is "normal" because with sRGB for example it had a yellowish tinge.

Did you switch on HDR? With HDR I can't influence the color profile and it gets a yellowish tinge again :D

Hi, guys,

i have set the ICC profile of @LRT as default which wirlick fits very well for me. Many thanks again :)

Now it is so that the profile is loaded on startup but then another profile is activated which is much more yellowish. I already suspected the Nvidia driver but even after uninstalling it with DDU and then reinstalling it the problem still exists. When I manually select the ICC profile it remains active. On the next reboot it will be the same again.

Do you have an idea what this could be?

Also, the monitor speakers are no longer displayed in the sound settings. Are there any drivers for the screen? On the Iiyama homepage I didn't find any.
 
Probably a long shot but perhaps Windows night mode of ICC profiles is enabled? This option applies a lot to yellow to the displayed colour space (or technically speaking reduces blue).

Another possibility is that Radedon Configuration software overwrites your ICC settings if Custom Colour option is enabled in the "Display" section. This might help: https://www.amd.com/en/support/kb/faq/dh2-021

Oooor... your iiyama monitor has COLOR SETTING set to something else than normal/sRGB. Possibly "Warm" if you're seeing a lot of yellow?

If that doesn't help, is there another other yellowish profile explicitly listed in the list of Windows ICC profiles?

I actually have to take a look at the Night Mode.

In the Nvidia graphics driver I have set that the settings are made by the system and not by the driver. That was my guess at first.

The color settings of the monitor are set to "normal" and then "user defined 1" but I did not make any changes here. Only your profile loaded with the default settings :) I only lowered the brightness a bit.
As soon as I switch to sRGB I can't influence the brightness on the monitor anymore.
 
I've now printed a sample photo and compared it with the ICC profile used with the iiyama. Firstly, I noticed that Windows 10 first loads some default profile and a couple of seconds it switches to what appears to be the correct ICC profile I generated. This correct ICC profile might be very different from the one that Windows used at startup. In my case a cool temperature profile is loaded by Windows, only to be replaced by the X-rite created profile 5 seconds later, which is a bit warmer. To make sure which profile is the one I want (whether it's the first one loaded by Windows, or the second one activated a moment later) I printed a sample photo using my wife's heavy duty printer she uses to for her customers, this printer has a very well balanced and profiled ICC used by professional photographers. In my case the second profile (slightly warmer) is a definitive match with the printed sample. It could be that in your case the correct profile is loaded for you but then it becomes even warmer for some reason, the result being some yellowish colour space.

As promised I've now generated a new profile captured at brightness set to 50% at iiyama's COLOR TEMP. set to NORMAL (it's in the dropbox folder).
