Hello,
Thank you for the time to read this and helping me out.
Problem: Dell U2410 Rev A04 is always entering power save with display port or VGA. Tried it with two different computers.
Story: Monitor was working perfectly fine with display port until I turned it off and went out of state for two weeks. Came back, I tried to reconnect and the monitor was entering power save mode. I use a Thinkpad W520. I can connect this computer to another monitor just fine. While the computer is on and connected to the monitor, if I pressed the button above the power, it says there is no signal from the computer and move mouse to wake up. Also, I have noticed the initial sound of pressing that button is dampened. It is very short and quiet compared to the usual audio feedback. This does not occur when I repress that button or if I press the power button first. The monitor is still in warranty but I prefer not to send it in as Dell will send me a refurbed one. I have browsed around the web but most problems are caused only by switching to a display port or are not resolved.
Thanks Again.
