My letters are to small on my computer i cant even read them there increibly tiny> i know how to change the resolution but i cant even see the letters to do that i need help.

you don't say what windows version you are using
windows 7
Click "start" type in 'font size ' left click "make text larger or smaller "
adjust and click "apply" and "OK"

Did you icons get big too? Pressing Ctrl + Mouse Wheel Scroll with make your icons bigger (also Right-Click > View > Large, Medium, Small). Did your resolution change? In Windows 7 and 8, you can check your resolution by right-clicking on the Desktop and select "Personalize". From there, select "Display" located to the lower left of the window. This should show you three options: Smaller, Medium, Larger. Choose the one you like the best. From here you can change your computers Resolution by clicking "Adjust Resolution" and select the one that shows you the most screen that you are able to still read. Most websites are designed to a minimum of 1024 by 768, so I would select at least that.

Change resolution. Right click on Desktop > Properties.

choose:

Start

Control Panel

Appearance

and adjust resolution to size that is needed.

may be it caused by your computer has to big resolution, change the resolution more smaller
for example 1024X768

Go into the display resolution. Right click on your desktop and select Personalize if your using Windows 7, then click Display. From there you can resize.

clik start then control panel then classic view then display and then select from drop down menu ...set it to 1024 x 768 resolution this should help

You likely have your resolution too high.  I prefer my resolution high but I can read small writing easily.   To change this right-click your desktop and choose personalize then display settings  adjust to a lower resolution but try to keep the aspect ratio similar to the ratio of the monitor you are using or the image will look squished.  once you have finalized your decision you will have to tweak it using the controls on your monitor to stretch the picture out to the edge of your monitor.    Also you can use the ease of access in the control panel for an on screen magnifier, or simply increase the font size in personalize (left column) adjust font size (DPI) (dots per inch)

right click on the desktop ...>properties....>appearance.......>font size....>change to large.............

This monitor will only have a sharp image at a resolution of 1680 x 1050. Any lower setting will result in blurry images.

In an LCD the pixels are fixed, and using any resolution lower than the optimal will cause blurry images. This is called Image Scaling:

If that resolution causes the icons to be too small, you can change the DPI setting to 120 from 96, that will make them larger
