U2415 - How to get my new monitors to stop dimming themselves

Unfortunately I do think it is the monitor and there is just no way to turn it off.

The operating system and graphics card are not new. My old monitors did not do this.

The product page for the U2415 even says the monitor does this.....

"Enhanced power management with PowerNap enables the Dell Display Manager to either dim the monitor to the minimum brightness level or put it into sleep mode when it is not in use."

So it sounds like a good ole fashion design flaw.

Please put in a request for a fix. Whether it be firmware or drivers or something. Either way I'm going to have to return them, unless there is some way to turn this "feature" off.

I do not see anything the U2415 User's Guide, OSD (On Screen Display) Menu, page 37 which has control over this. This has to be either a setting in the operating system or within the GPU control panel.

Did you install the additional Dell Displays Manager software? If yes, uninstall it, reboot, and retest. Or open it up, go to Options, remove the check. Retest. 

Confirmation would have to come from other owners on this Forum. He must have been talking about another model. The U2415 does not have that setting in the OSD.

I will try removing the manager software but it was doing this before I installed the manager software so I think its something that runs on the monitor itself.

Is there anyway to get a confirmation on if there is something built into the monitor that makes it do this?

I called tech support and the tech said his monitor has a setting to turn this off in OSD. But Ive been through the u2415 OSD and have seen nothing to turn it off. I think he said on his monitor its called "energy smart".

Right, he was on a different monitor. But it sounded like his monitor had a similar OSD to mine but his had an option to turn off "energy smart" and mine doesn't.
