L220x short flickering

[ Edited ]


just bought a L220x, very impressive LCD, but I've got a problem:

In irregular intervals the monitor flickers - really short, not longer than 0,1s - But very annoying.
I installed the latest drivers for my VGA-Card (Nvidia Geforce 7900GTX) and for the LCD (L220xwC(Digital))
SoftOSM is also installed. The Frequency is set at 60Hz.

Sometimes, when the LCD flickers, i see small black squares on the LCD, but only particulary. 

With my old Monitor (Samsung 701T) I've never had problems like this.

Anyone suggestions? Thanks very much!

Edit: In the System-Events I found logs like this:

" 0011: The following display assets have been discovered on this computer - 1. Lenovo L220xwC, ID=LEN1151, S/N=VL-58573, Age=6 hours Display asset attributes have been written to c:\program files (x86)\softosd\softosd.mif "

I'll watch the events regarding the flickering, but I think it has a connection... Obviously the SoftOSM is not started, but the logs are written?!

Re: L220x short flickering

There's an unlying service associated with softOSM and HPD.


1. In with Windows "Run" box type "services.msc" and click Ok

2. In the list ofServices, find softOSD and right-click on it

3. From the popup menu, select Stop


If that stops the periodic flicker, then you can either uninstall softOSM altogether or simply disable the hotplug detection mechamism from the softOSM menu.

Re: L220x short flickering

Hi swamped,

wow, thank you very much! The flicker stops when I stop SoftOSD (also by killing the tasks in the Taskmanager)
Thanks a lot!
