Colors off and not bright at feed

Hello, love this project but I noticed color feed doesn't match what is on the screen, is off by a lot and brightens doesn't give maximum. When my lights just gets on in standby mode and waiting for app to start and I'm getting color cycle - all color looks bright and rainbow. But when software starts it looks like only 50% brightens and color is off - for example if screen image is yellow - it shoes like red or pink, if its green it looks more like blueish, if its white - looks like blue.

On soft I have all color correction at 100% but it is still doesn't give same brightens as standby mode

Do u guys have same issue.
I can do video to show.

Any suggestions?

Here is actual data feed to see brightnes difference and color distribution(im posting more photos as well):

Thanks for helping and looking into it ;)

it looks like it uses way to much blue in all it does but the settings say, you have not touched the white balance.

Things to check:

  • Open the Preview-Tab in the settings window. Does the preview of your screen there look like the actual screen or is there already a color shift?
  • Check the code you flashed on your arduino. did you change something there?
  • try adjusting the white balance by reducing blue by a lot, this might be it already. the color reproduction is not that great in most led strips

regarding the brightness, i cannot really tell something is wrong actually. there is a brightness setting in the arduino code, but it affects the demo mode as well so there should not be any difference between the modes.

adrilight/Arduino/adrilight/adrilight.ino

Line 5 in ef7873e

#define BRIGHTNESS 255 //range is 0..255 with 255 beeing the MAX brightness

did you wired in more than one power input into the strips?

I have 1 power adapter to power strip and data contacts to Arduino board. But if there would be any issues with power that would effect demo mode as well, right?

I did video for performance page but I don't understand how to use that page.

Can you do screen or video of explaining?

Thank you

The preview page looks fine.
please post the arduino code you flashed on the arduino and provide a url or photo or something, what led strip you bought.

this is sooo weird! at least after turning the white balance on blue to zero, the blue should be gone completely!

Hi, is there is possiblity something wrong with Arduino library - but than im thinking would be same issue with demo mode! Demo mode colors looks awesome and correct but feed too much blue like you said!
here are my code and extra info

original project was led build from this instructions: https://www.instructables.com/DIY-Ambilight-Using-Arduino-Nano/

Hi, I figure out...my 2811 color led code wasn't build the same and I just swap code and now all works. Thanks you
