I have a problem with size on monitor

The stated native resolution of this monitor is 1600 x 900. If you set your display resolution to that in your computer's configuration, you will get the sharpest display.
Note that there is always a trade-off between sharp image and the size of displayed items on the screen. By that I mean that if you set your display to 1600x900, your text will be sharp, but it will be smaller on the screen than if you see the resolution to 1280x720, for example. The trade-off would be larger text (say, if you have vision problems), but the text would not be as crisp.
Experiment with a few different resolutions to see what looks the best and has the best text size on your screen.
Note also that most browsers will let you enlarge the web page on your display by pressing Ctrl+ repeatedly until you get the size you want. Pressing Ctrl- will reduce the web page displayed size.

IT IS NOT HARDWARE PROBLEM
Change screen resolution

Screen resolution refers to the clarity of the text and images on your screen. At higher resolutions, items appear sharper. They also appear smaller, so more items fit on the screen. At lower resolutions, fewer items fit on the screen, but they are larger and easier to see. At very low resolutions, however, images might have jagged edges.

For example, 640 × 480 is a lower screen resolution, and 1600 × 1200 is a higher one. CRT monitors generally display a resolution of 800 × 600 or 1024 × 768. LCD monitors can better support the higher resolutions. Whether you can increase your screen resolution depends on the size and capability of your monitor and the type of video card you have.

Text and images are sharper and smaller at high screen resolutions

Text is larger and easier to read at low screen resolutions, but images are blocky and fewer items fit on the screen

1. Open Display Settings by clicking the Start button , clicking Control Panel, clicking Appearance and Personalization, clicking Personalization, and then clicking Display Settings.
   

2. Under Resolution, move the slider to the resolution you want, and then click Apply.
   

seems to be the resolution or your video driver. Go to http://support.dell.com
select home user then DRIVERS AND DOWNLOAD ,then enter your service tag and in the video category look for your vide driver.
Try that

That depends on several factors. Obviously a 3MP image is going to be larger than a 2MP image and thus you'll fit fewer of them on a card. Image quality also affects the size of the file and thus the number of them you can put on the card. The subject of the picture will also affect the size of the picture, the more detail in the scene the more bytes it will require.

This page on the manufacturer's web site gives rough estimates of the file size (and capacity) for the various modes: http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&tabact=DownloadDetailTabAct&fcategoryid=320&modelid=11086#ModelTechSpecsAct

Set your setting to "Secondary Screen Only"
As your setting for both screen doesn't seems to be adjusted but you can try turn it off.

If you just want to change the size of the font of the web pages you are visiting...all you have to do is hold down the CTRL key while tapping the + or the - key the will increase and decrease the font size.

To check the resolution just right click in an empty area of the desktop and scroll down to properties....you can play around with the resolution there....don't worry, you get 15 seconds to decide if you like the setting before it reverts back to the previous setting.

Since this is a CRT monitor, it doesn't have a native resolution like LCD monitors. You need to adjust the veritcal and horizontal sizes to fit the monitor. On the front of the monitor there are some menu buttons. You need to open the on-screen menu, then navigate to the Horizontal Size and Position menu, use the plus and minus buttons to grow and shrink the image. If it's not centered, use the Horizontal Position menu to move it around. Use this same system for the Vertical menu and you can get your image to fit your screen. By the way, you should have your operating system running with a white (or light colored screen) up when you do this so you can see all the edges of your desktop. The buttons are tricky, but they kinda make sense. Good Luck!

Printers try to fit web pages on a single sheet of paper. If you configure the printer, in the print dialog, not to shrink images and text to fit the paper, it will print on multiple sheets of paper, but the correct size for the images and text.

In a Word document, it depends on what font size you have selected. Most people would rather have the web page print on a single sheet, with smaller images and text than were on the monitor; than tape together multiple sheets for 100% size printout.

There is nothing wrong with the monitor, the issue is that the web page you are looking at is designed for a lower resolution than you LCD is set for (Web pages are normally designed for 800 x 600 or 1024 x 768) you like have a wide aspect ratio monitor.

As I sit here writing this on my 12" wide aspect LCD I have a 2" wide white space on each side of my screen due to my 1280 x 800 aspect ratio.

The issue is one of WEB PAGE DESIGN not the fault of your computer video settings. The web page is written using page frames and fixed aspect ration settings to ensure that the page displays properly regardless of monitor type.

If you had a high end LCD (WUXGA 1920 x 1200), the web page would fill the upper left 1/4 of the screen.

If you lower the resolution of your display, then you'll have fuzzy icons and text, so essentially, get used to it.

Eventually, wed design will catch up with current display technology.

reinstall the driver for your monitor or adjust the resolution in the desktop properties
