I am trying to control brightness on my Philips 288E2. Monitor connected to Windows 11 using a Intel UHD Graphics 750 via DisplayPort or HDMI. (I've tried both)

I've tried various desktop programs, scripts, all report error. For example Monitorian say

PHL 288E2 Monitor is not controllable. DDC/CI is not supported or enabled

The monitor spec states in user manual:

Plug & Play Compatibility: DDC/CI, Mac OSX, sRGB, Windows 10/8.1/8/7

See: official user manual

There is no such setting in monitor menu Enable/Disable DDC/CI, neither user manual mentions it.

Edit: I've downloaded official drivers and Philips official SmartControl. It displays the similar menu as the monitor's native menu but all menu items are disabled (including Picture/Brightness, etc, except Setup/Information. which btw shows DDCCI: NO. In the native onscreen Setup/Information there is no such data, a way fewer parameter is displayed

Question

What am I missing, and how can I configure my system OS? Monitor? to enable DDC/CI, so I can use programs to control brightness?

For my part I used the Desktop dimmer application, it's a free application that allows you to control the brightness of each screen in HDMI, compared to other apps that do similar things and which doesn't work , this one really works (for me anyway), the application is free.

Of course this only solves the problem in appearance and not in substance in relation to the DDC/CI but I think it can already help some people.

My own conclusion is the the Philips 288E2 is undoubtedly a very good monitor, but it just does not do what you require.

The description of the terminal and its manual contain lots of references to its in-built smart technology that will automatically adapt the picture as regarding brightness, contrast, game mode etc. There is no mention of any PC control and especially DDCCI is showing "NO".

My conclusion is that Philips were too confident of the smartness that they built into the 288E2, so confident that they forgot about program control. They allowed setting parameters by the OSD, and were very confident of being able to follow them automatically in all cases and situations.

My advice is to return this monitor and get another that really supports DDCCI. It's better to verify important details in the publicity against independent reviews and user cases, because the publicity materials were not written by engineers.
