Monitor ST2410 flickering
Hi,
I just got my new st2410 monitor 2 days ago. It is currently connected to my laptop using a VGA cable.
The problem is when I plug my laptop to charge it, the monitor starts flickering. When I remove the laptop's plug from the socket, the monitor stops flickering. Is it
something to do with the voltage regulator of the monitor?
Do you have any solution to my problem? My laptop is an XPS m1530.
Thanks

Is there another computer to check the monitor on to see if the issue can be replicated?

Hi,
I tried it on a Toshiba laptop. I got the same problem. It flickers when the laptop is on power and does not when it is on battery.

Do both laptops use a 2 prong or 3 prong power cord?

The laptops have 3 prongs. Does it make a difference if it is 2 or 3 prongs?

It does. You cannot use a 3 prong on both the laptops and the monitor. They create a ground loop. Is the M1530 under warranty? What are the part numbers on your power cord and AC adapter?

Yes. It is still on warranty. The model of the AC adapter is DA90PS2-00
Ref no. : ADP-90AH FA
There is another number under the BarCode
CN-0UU572-48661-866-86XB - REV A01
I'm not sure what number you need...
Thanks...

The number is : UU572
I tried my monitor on a normal PC which has a 3 prong power cord and it was not flickering. How is it possible that on the laptop, it is causing the grounding loop and not the PC since both have 3 prongs power cord?

A desktop PC only has the power cord. A Laptop PC has the brick and cord. The Laptop PC power cord must be 2 prong. I need the following in a private message -
Name:
Email Address:
Shipping address:
Phone number:
Monitor Order number or PC Service Tag number if purchased with a PC:
Monitor 20 digit PPID number found on the back on a label or on the slider card on the left rear:
Reason: 2 prong power cord for XPS M1530

Look at the laptop plug. Is it 2 prong or grounded 3 prong?

I am having the same problem on my desktop pc, netbook, and Xbox 360. Although it is only on black moving surfaces. Turning off dynamic contrast doesn't work. I think I'm sending it back, and ask a replacement. Dell disappointed me very much and I don't think I will buy a Dell monitor again. Maybe you guys have any ideas?

Did you try using different video cable such as the hdmi cable?
