Hi, I know the brightness of over 1000 nits open show up when playing HDR contents. I read that there is an app that can increase the brightness of the laptop even during normal operations without playing HDR. What is the name of that app?

Working in the sun with my 16” M1 Max at 1000 nits, see picture below, using the Lunar app to get the brightness from 500 to 1000. The Vivid app can also do this but using Lunar since I had already paid for that app. I activated both at the same time in the screenshot (so interestingly one half of the monitor seems even more bright due to Vivid being on top of Lunar).

Never been able to work with a laptop outside in the sun before, amazing.

(There are already a lot of threads on whether temporarily enabling XDR and so on is safe, after reading those I believe it is)

Incredible laptop overall, have had it for 5 months now. Speeds through everything, all day battery life whilst doing data analysis, amazing screen to look at.

Is the fan still dead silent after using Lunar or Vivid for a long time?

Yeah, even when using Lunar + Python data crunching (single threaded) + driving iPad as second monitor through Sidecar. I only heard the fans when I was actively benchmarking the laptop for fun, and even then could hardly hear it.

There are a couple of apps that can do this:

- Lunar was the first to do this and uses a method to manipulate pixel brightness values directly + it uses some undocumented/reverse-engineered API calls. It works well.
- Vivid and (as a cheaper alternative) BTT does the same and uses overlays - this also works as advertised but has some caveats (mouse cursor and OSD remains unaffected, might mess up screenshots unless the overlay is removed temporarily etc).
- BetterDummy's v1.2.0 beta also manipulates pixel brightness values like Lunar but does not use undocumented API calls + it has some other features, like automatic calibration so it works both for XDR displays and any other HDR external displays out there. It's a beta though.

There are currently 5 different methods to achieve the brightening effect effect (these can be grouped into 3 distinct categories), I think the one used by BetterDummy is the best so far. But I am the developer of BetterDummy and MonitorControl so I might be entirely impartial about this. ;) Afaik Lunar will also upgrade to the newer method (not needing undocumented APIs) utilized by the BetterDummy beta as I shared with the developer how this works.

Know any good Windows version to increase the brightness of LCD screen connected to a PC?
