- Turn off your monitor, then turn it on by simultaneously pressing the three buttons circled in blue above (Menu, Plus, Power).
- To access the service menu, press the button circled in yellow above (minus).
Exit the service menu as you normally would. To return to normal user mode use the soft-power button to turn the monitor off and back on again.
This should also work great with 2404WFP, 2405WFP, 2406WFP, 2407WFP, 2704WFP, 2705WFP, and 2706WFP where those panels exist (maybe not some years). My guess is the 3008WFP will also use the same combination — I don’t know about earlier years as they had fairly different display processing hardware.

As of now this is probably the only place on the internet where that information is available.
How did you learn this?
Earlier models of the same monitor used the same access method :) Post amended to include these.
You can add the Dell 2709W to that list. But this model uses touch buttons on the side, not physical buttons. The pattern is the same, and ends up being the 2nd, 4th and 6th (power) LED buttons. And then the 3rd button to enter the service menu.

Combination confirmed to work on 3008WFp.
this also works for u2410,
For the 3008wfp, the monitor will come on. Then hit the “-” and look on the upper left.
Look under “Hour” to find the hour usage of the monitor. Mine got 121 h as I got a great deal on a almost new monitor for $790 after bing and ebay bucks.
Even earlier models than stated work… e.g. works on my 2208WFP
