You know that you can increase max brightness and sub brightness in the service menu?
By default, max brightness is set to parameter 201 (it can go up to 255), some users after increasing max brightness to 255 were able to see difference in contrast, etc…
I am not sure, I can see some differences, but also it could be placebo effect.
To enter service menu:
– turn off monitor, keep pressed button 1 and 3 (in order, under menu stick first button is 1), turn it on, release both buttons when screen is on and then press button 4.
You will see a small blue screen on the top left side of your monitor, you use menu dialer to go through options.
Keep us posted if you see any changes, anyone.
Cheers.
