Old laptop, newer LCD monitor

System manufacturer / System name
August 21, 2009 at 14:24:32
Specs: Microsoft Windows XP Home Edition, 1.506 GHz / 1023 MB
I have a Dell Latitude D610 laptop computer that I would like to use with an HP w1907 LCD monitor. The laptop computer has an analog video output, the LCD monitor has an analog video input.

The combo works, but not well. The display on the w1907 is not crisp and well defined. The images seem to be fuzzy.

Periodically the w1907 displays a message directing me to give it a 1400X900X60Hz input. But the D610's maximum available screen resolution is 1024X768.

Is it practical or possible to use the two devices together? If so, how?

Thanks.

Steve

I don't know if it will help but it can't hurt. Try updating the video drivers for your laptop. That may allow you to change to a resolution that you need. Get your drivers at the link below.

This ia an unsurmountable problem related to the way LCDs work.

LCDs have a native resolution at which they work at there best. At any resolution other than there native resolution they have to perform some digital jiggery pokery in order to make the picture fit. This is why you are getting the fuzzy image. Some monitors perform this jiggery pokery better than others.

With a native resolution of 1400 X 900 it is having to interpolate pixsels in order to fill the screen with 1024 X 768 pixsels and it doesn't like it becaase it is hard work.

It works this way becasue LCDs have a fixed pixel size where the older CRT monitors have an infinatley variable pixel size. The only way you can get round the problem and use two moitors with the laptop is to aquire an LCD monitor with the same native resolution as the laptop.

There is no option when using an external display to run them at different resolutions, like you can on a desktop?

That is why the OP is getting a fuzzy display. He is running it at 1024 X 768 where the external monitor wants 1400 X 900 which the laptop is incapable of..

He needs a monitor the same native resolution as the laptap which is 1024 X 768.

You misunderstand my question. I will rephrase it. Can a laptop display a DIFFERENT resolution on an external display than on the integrated display.

Desktop integrated GPUs are capable of that. The limiting factor in that case would be the correct drivers.

Your Dell laptop has an ATI graphics chip inside. You need to go to the last link below to download the latest drivers for it. On that screen is an option to enter the service tag. Do that because there were multiple graphics chips used with that model. Download the appropriate drivers. You may also need the Catalyst control center in order to select a different resolution for the external display. I’m not 100% sure on this, but the links below indicate your graphics is capable of that.
