T400 blurry external display

2010-03-11, 10:31 AM

Hi,

 

Just wondering if there is anybody else out there connecting their T400 to an external monitor of FULL HD res (1920x1080) through a VGA cable?

 

I got a rather blurry output. I have set the monitor to its naive resolution, auto-adjusted, but nothing seems to help.

 

Is this a problem of my new monitor or that VGA output on T400 struggles to deal with the high-res output?

 

Thanks.

Thanks.

 

Yes, the res. on ext. monitor is set to 1920x1080. I haven't tried changing the VGA cable though, which came new with the monitor. I tried with my other laptop as well, and it's even blurrer :-( This lead me to think that it is a laptop issue, whose VGA connection can not fully support FULL HD.

No

It is prohibited by the bloody movie industry. 1080 p is not allowed. You may be able to get an interlaced signal or it will down-sample to about 480 lines.  This is true of any computer.  Look up a software called AnyHD, it may solve your problem.

You probably are thinking about HDCP for 1080p blueray/hddvd play back which is a different context all together. 

 

VGA can do 1900x1080 just fine

 

I have two 24" 1900x1200 from my T60 (NVS 400) and series 2 dock (one from DVI, one from VGA) so I don't think graphic card is the issue (does docking station make a difference? probably not)

This might be a dumb question: but if your monitor truly 1900x1080 (16:9 aspect) or could it be 1900x1200 (16:10 aspect)?  If you're feeding 1920x1080 signal to a 1920 x 1200 native resoultion screen, it will have to stretch the image by 120 vertical pixels to fit its native resolution, which would likely look blurry.

I just got a T410 with integrated graphics (Intel Graphics Media Accelerator HD-AMT) and I'm having a similar problem. I have a 24" Samsung monitor that supports 1920 x 1200 pixel resolution and it worked fine with my Dell Inspiron which had exactly the same size screen as the new T410 (14.1" with 1440 x 900 pixel screen resolution). With the Dell, I can slide the resolution selector all the way up to 1920 x 1200 and when I hook it up to the external monitor, I get a fine, crisp image. With the Lenovo T410, the highest resolution I can select is 1440 x 900 and when I hook up to the external monitor, the display is pitifully blurry. If anyone has a suggestion on how to fix this, I'd be eternally grateful.

 

Thanks.

change the resolution using the intel display tray, also are you doing a screen clone or extended screen setup.

Thanks. I finally figured out that I can't get the higher resolution on the external monitor so long as I'm cloning the display, but when I set it for a single display, the higher resolution settings become available. That wasn't necessary with the Dell laptop I just replaced.
