    I have the same problem. Mine started doing this after 4 months of use. I have it connected with the DVI connector to my DELL Precision m6300 Notebook and the highest resolution for the Monitor. Every 5 min the screen will go black, but I see the power button is still green and my laptop is running fine and it's working on the Laptop LCD. I have to turn off the monitor and turn it back on and it will say something alone the line of "Digital output " and work again for antoher 5 mins before it happens again! What's going on. I'm using a 19" Older Dell LCD Monitor and it's working fine. It's gotta be the Dell E228WFP Lcd monitor.

    Same issue as above. The E228WFPc is my secondary monitor attached to a laptop. By the end of the day it starts to exhibit this behavior. The attached LCD doesnt malfunction ruling out powersave or graphics card. Changing from DVI to VGA doesn't change the problem, and it only really starts manifesting at the end of the day (backing up the heat-related diagnosis). I can also still faintly see the image - definately the backlight.

This is a backlight problem. I can still see very faint images moving when mine goes black, i.e. while watching a movie. Anyone know how resolve this backlight problem. Probably a faulty hear sensor if it has one.

It's heat related and possibly a backlight issue - mine only does it when the monitor has been powered on for about 2 hours. If I turn it off for an hour, I can get another 2-hour stretch out of it. Happens in self-test mode, so that's the cruncher. It's taken 2 days and many laborious hours on the phone, but Dell is sending me a replacement monitor tomorrow. There are more people with the problem here: http://en.community.dell.com/forums/t/19245356.aspx. Hope you get yours replaced too...

You may have a loose connection. Check your power cables and vga/dvi cables (the one that connects your computer to the monitor). Make sure everything is in tightly.

Auto detect analog


Hi Jessica,
Dell E228WFPC/E228WFP does support displays with 1920x1080 set resolution via DVI connection while it is restricted to validated Dell brand displays:
  • The restriction applies to resolution higher than 1680x1050 via DVI connection.
  • No restriction with VGA connection, which supports up to 1920x1200.

If you use a DVI connection set your computer's resolution to 1680x1050.

Power drain


There is a lack of communication between the monitor and video card. Try reseating if add-on video card. Make sure monitor is set to correct input, like VGA (analog), DVI, HDMI, or Display Port. Try testing with another monitor.

Dell228wfp on start up pwr on is green screen


Either the cable is not connected to the proper port or the display-source is not configured properly.Here's what you can try.
  • Ensure that you have connected the VGA/DVI cable in the correct port. If you have an extended graphics card in your computer, use a DVI cable(Digital input) else the VGA would be the only option available.
  • If the cable seems to be plugged at the right place, press the first button from the left on the front panel of your monitor (Button 1 shown in the front view: http://support.dell.com/support/edocs/monitors/E228WFP/En/ug/about.htm#Front_View), once. This toggles the digital mode to analog mode of your monitor, and vice versa.
  • If the first two steps do not work, its not an issue with the monitor. It could be a failing cable or a defective video card, or the system itself is not completing the POST.

Thanks,
Abhishek

Screen Goes Blank


Ive seen this on other monitors. Look for a 1 and 2. Some monitors do NOT auto detect a signal, and this one might not. Look for a way to set the monitor from Digital input to VGA input. Try that and see.
