External display with shifted screen

Greetings,

 

i bought Lenovo T520 with nVidia 4200. But when i connect external monitor (LG 245WP) via displayport (converted via dispayport to HDMI) i get shifted screen. And LCD is connected as TV, not as 1920x1200 monitor. There is nothing i can change, all drivers are up to date.

 

I'm using Windows 7 64b PRO.

 

Please, can you help me to fix it? When i use VGA, all is working.

 

Thanks, Moreplavec

Re: External display with shifted screen

If I recall the image via the display port and your converter to HDMI is blow a little larger. I seem to recall that when I connected mine.

I am not aware of any adjustments myself but then again only used it once to see if it worked when I first got my HDMI converter.

Re: External display with shifted screen

I found it might be EDID problem and i need to edit something to change my computer stop thinking about my LCD as TV, but as 1920x1200 monitor. Even software is displaying 1920x1200, still LCD gets informations like TV.

 

Is there any Lenovo support? Or they just sell the hw and now it's my trouble?

Re: External display with shifted screen

The real support is via the phone to the support team. This is an unoffical support forum although there are some Lenovo staff on this forum.

It is a user forum primarily. The resolution should be selectable for the output device especially if display port to display port connectivity is used.

Re: External display with shifted screen

Resolution aso is all correct. But for some reason (EDID) it's handled like TV. It's not about setup someting, but about to change Windows registry.
