Failed to set brightness of secondary display - Lenovo ThinkVision L2452p 24-inch #11

adhulipa · 2016-03-22T13:21:50Z

This is the error I get when setting brightness

brightness -d 1 0.05
brightness: failed to set brightness of display 0x2b845104 (error -536870201)

The text was updated successfully, but these errors were encountered:

kzahel · 2016-04-06T19:05:31Z

Same here on Dell U2713H
Wondering if attaching a usb cable to the monitor would help. I don't have one though...

brightness -d 1 -v 1
brightness: failed to set brightness of display 0x2b2861cd (error -536870201)

adhulipa · 2016-04-06T19:13:24Z

I read somewhere about that trick too (attaching USB cable).. Not really sure how that would work... I did try it out though ... didn't work either

davidlc9113 · 2016-07-05T07:24:11Z

I find it is almost impossible. You can refer to following materials.

nriley · 2016-07-05T12:19:42Z

https://github.com/superduper/BrightnessMenulet and/or https://github.com/kfix/ddcctl may work for you. It sort of works for me with my current display, a LG 27MB85R (setting contrast works reliably; brightness and volume don't, and querying volume hangs my Mac). See the caveats at the bottom of the ddcctl readme, though; it may also hang your Mac, display or both.

In any case, the above seems quite flaky and I don't really want to release software that is likely to crash your Mac or display. If Apple decides to support DDC control in any serious manner I'll reconsider of course.

FranklinYu · 2017-02-08T09:02:17Z

Really disappointed at Apple; DDC/CI is so easy on Windows and Linux. Is there anywhere I can yell at Apple about it?

auduchinok · 2017-02-18T21:05:24Z

@FranklinYu, try their bug report tracker, bugreport.apple.com. Don't think it'll help though.

arcseldon · 2017-03-05T04:38:17Z

This failed for external Dell P2715QT - 27" Monitor.

brightness: failed to set brightness of display 0x2b10190e (error -536870201)

but works for the built-in mac book pro screen.

I have an LG UltraFine 27MD5KA and I get the same error:

jathu · 2018-04-12T03:14:24Z

This script worked for me: https://github.com/kfix/ddcctl

I'm using an external Acer monitor.

latenitefilms · 2020-04-11T23:27:33Z

MY LG UltraFine 5K also fails when connected to my MacBook Pro via USB-C:

brightness -l
display 0: main, active, awake, online, external, ID 0x1b56fe4d
brightness: failed to get brightness of display 0x1b56fe4d (error -536870201)
display 1: active, awake, online, built-in, ID 0x4280c46
display 1: brightness 1.000000

However, I can use the brightness keyboard shortcuts to control the brightness of the external monitor, so macOS can definitely do it.

Also, as @jathu suggested, ddcctl also works.

thewellington · 2020-04-14T02:40:25Z

hi @latenitefilms if you download and compile the brightness code yourself it will work with you LG 5K UltraFine display

elijahchancey · 2021-04-05T17:38:55Z

I've got a Mac Mini with an M1 chip, MacOS 11.2.3, and an LG Ultrafine 5k Monitor. Using homebrew, I had a similar error in the issue description. I then downloaded the source, compiled it, put the binary in my path, and it works fine!

@nriley If you'd like me to provide further information, I'm happy to.

nriley · 2021-04-05T17:48:47Z

Yeah, I think we just need to figure out how to get the Homebrew formula updated... I didn't create the original one!

tbrodbeck · 2021-05-27T09:30:15Z

hi @latenitefilms if you download and compile the brightness code yourself it will work with you LG 5K UltraFine display

Thanks bud. Same on MacBook Pro 15'' from 2018

I got sam error, and I am trying ddcctl and BrightnessMenulet, will update soon.

----- after tested -----
BrightnessMenulet is working for me, just download with the link
https://github.com/superduper/BrightnessMenulet/raw/master/BrightnessMenulet/Brightness_Menulet.zip
unzip, run the app, you will get it in top right corner, click and use it.

I am using 10.11.6 and have 2 ex-monitors it's working.

worked for me, and was very simple to compile too.

same error.

foolip · 2024-03-04T08:50:58Z

I got the same error with my LG UltraFine 27MD5KL and as others on this issue suggested, just building from source and it works. @nriley is the binary in Homebrew outdated?

nriley · 2024-03-05T04:30:18Z

@foolip Yes, it is. I didn't upload the Homebrew package; someone else did and abandoned it.

thewellington · 2024-03-05T20:07:18Z

Just created PR 49 to suggest the removal of hombrew from the README if there is no support for updating homebrew.
