resolutiontftwindows xp
I’ve been asked by a visually impaired friend whether it’s possible to improve the image quality of a TFT that’s not running at its Native Resolution.
She’s recently purchased a Samsung SyncMaster T220, though wants to use a low resolution so that everything appears nice and big. However, at a low resolution the text on screen appears very blurred.
Does anyone know of any software or graphics cards that would help? (She’s using XP.)
Many thanks in advance for any help.
I know this isn't exactly what you're asking for, but may I suggest increasing the font size in your display settings if they are too small to read? Running at native resolution is generally optimal if you can at all stand it.
From the page you linked there is a manual that shows the following:
It appears that your monitor has two default resolutions that it natively reports and I suspect that if your graphics card does not support the higher horizontal frequency that your monitor expects for its true native resolution and so is falling back to the other "native" resolution of the monitor.
-=EDIT=-
Looking at your comment I would fully expect your graphics card to support that resolution, but I believe above 1900*1200 you require "Dual Link" DVI for it to work.
Next I would have a look at the cable you are connecting to your monitor, that resolution may require a cable that is "Dual Link DVI" compatible. I've found an image of what to expect from various cables but it may be that you simply need to buy a higher quality cable. If you have any other DVI cables you can try then I would start there.
-=EDIT=-
Yep, Check the cable or get a new one (information from this page):
The dual link DVI pins effectively double the power of transmission and provide an increase of speed and signal quality; i.e. a DVI single link 60-Hz LCD can display a resolution of 1920 x 1200, while a DVI dual link can display a resolution of 2560 x 1600.
Best Answer
Is she running at a low resolution because text is too small at high resolution? Change the monitor to its native resolution, and bump up the font size in Windows XP.
Follow the steps in this article.
EDIT:
If it's for other reasons, one way to reduce blurriness is to have it so that the resolution is exactly half. So if your LCD's native resolution is
1600x1200, try changing the resolution to800x600.
