T400 and blurry external monitor (ThinkVision L2251x)

[ Edited ]

Connecting my T400 (Windows 7) to my new Thinkvision L2251X montior through the VGA cord supplied with the monitor results in poor quality display, when connected either directly or through the advanced minidock.  I have not had this problem with my previous display (Thinkvision 1951).  I have checked to be sure that the t400 output is set for 60 hz and  1440 x 900 (the preferred "native" resolution that matches the monitor).  I have spent a month trying a variety of options including other resolutions and changing the dpi, but nothing improves the display.  I'd be grateful for any suggestions!

a 22 inch LCD would usually have the preferred resolution of 1680 x 1050... not the 1440 x 900 which is used in your 19 inch widescreen LCD.

The L2251 has a different display mode than mode 22 wide monitors, so that's not the issue.

 

Anybody know anything about DVI to VGA converters?  THe monitor model lacks an HDMI port and a DVl port.  It has a DisplayPort to receive a digital signal, but I don't have a way to plug it into the T400.

you would need to get either a Lenovo usb2dvi or advanced mini dock to get DVI connection. Otherwise you would need to get something like matrox dualhead digital edition to get vga to dvi conversion.
