README: Add Model Number for LG UltraFine 4k 2nd Gen #20

Closed mrackwitz closed 4 years ago

mrackwitz commented 4 years ago

Thanks for building this app. Here are my diagnostics for one LG 5k display (1st gen as I could find out now 😭) and 2 LG 4K displays (presumably 2nd gen, I just ordered them on Amazon last week?). Hope this helps. I got it hoping it would mitigate the auto-adjustment issue I'm seeing with my 5k display as previously described in #18:

my display occasionally seems to adjust the brightness when no discernible ambient light as changed.

Just to double check, for each display, do you see an option to enable automatic brightness?

This is what I see for my 1st gen 5k display:

As far as I know, for second gen UltraFines there should be an option to enable automatic brightness adjustments below the slider.

mrackwitz commented 4 years ago

Nope, I do not have this option for my 5K display. Only for the 4K displays. So I presume it's in fact a 1st gen?

OCJvanDijk commented 4 years ago

Yes, looks like it's a 1st gen, which is confirmed by the model number (thankfully).

Now with the model number of the 2nd gen 4k model you have provided, I have everything I need to distinguish 1st gen from 2nd gen. Thanks!

The next question is, how do I handle 2nd gen displays... I could either leave them alone and let them handle their own automatic brightness, or I could sync brightness to them anyway and treat them the same as 1st gen displays... I think the 2nd option is the best for most people.
