Sample Screen Color/Color Picker don't work on second monitor

[Avarones]

Giving some context: Last month I was working with a 24" and 19" monitors, then my Graphic card died and I bought a new one, buying a new 27" monitor together.
Formatted my computer, installed 3ds max, corona and everything back, everything working fine.

But I found out that the Sample Screen Color (or Color Picker) are not picking colors from the second monitor. It just appears to be picking a white color. Tried putting 3Ds max on second monitor, it doesn't work that way neither.

What could be happening?

Corona 5 / Max 19

Works fine for 2020 and 2019 corona v5, v4 on my end. Is your gpu drivers up to date? Also amd or nvidia?

Also note: It might be caused by the second GPU or by different DPI setting on the second monitor.

It never worked for me either (same monitors, single GPU, latest windows and drivers all year around), but this is some Windows setting imho though I am not aware which.

It works for me, but it samples wrong values on secondary monitor, so i always have to be careful not pick colours from it. It probably would be better if it wouldn't work, than to work incorrectly.

It seems to work fine here, Max 2020 and Corona 5. Tested both Corona picker and Max picker.
Could anyone with this issue please take a few screenshots showing what exactly they are doing step by step, or a video if possible, so that we could try replicating the behavior?

Hi Maru,

here I made a screenshot, and because it doesn't capture cross-hair, I made small green square of which area I sampled.
To better describe the issue, it's actually what Romullus wrote, it is sampling something (because the color changes as I move around), but it's not where the crosshair is.
My setup is 2 identical 32" 4k display with same DPI scaling (150perc.) and one vertical 24". I sampled from the identical monitor though, I didn't try turning off the vertical, might do later.

In this screenshot, where 3dsMax ends is the end of middle monitor, it's full-screen. I take back what I wrote about Windows issue, because I tested with Photoshop and that one samples correctly.

Correction - it only samples wrong colours from a picture that is open in windows photo viewer. CCP picks colours without any issues from anywhere else - tried in 3ds max itself, in affinity photo, even in windows explorer and in firefox - no problems across multiple monitors. So in my case it's just an issue with windows photo viewer, not with colour picker.

Sorry for off-topic - Juraj, is this how 3ds max 2016 looks on 4K monitor? How do you manage to read its UI? It's super tiny!

[Juraj]

And this is with 150perc. scaling :- ) I used only 125perc. for past two years but I feel my eyesight is worse since lately bit.
With 2016 scaling is terrible, you can see Corona text is scaled (to a point where some texts are missing from fields) but 3dsMax is only somewhere.

I can read it since it's 32" big monitor and I don't sit that far behind. But yes, I can't wait for improved scaling with 2020, at least I hope it's better..and working.

I would need binoculars to read this O_O

Did you tried new options in last windows 10 for up-scaling in properties?



I am also using 125% upscaling and this options fix issue for example blurry fonts in 3d coat

Works exactly as it should for me:

Different monitors
Windows 7
3ds max 2015
Corona 5

Just one question, which may seem weird, but I remember once case where a user did this: you are using the "regular" color picker, not the inverse one, right?

[Juraj]

For me, yes of course, that's why the sampled color is seen in left corner as it swaps that cursor.

Tested this again with Corona V5,V4,V3, 3ds max 2020.03, 2019.2, 2014, 1080p monitors. All worked as expected with both pickers with different sample sources.
