Windows 7 – Adjust Screen Resolution, Refresh Rate, and Icon Size – Remove Flicker [Tutorial]


Hello and welcome. This tutorial will explain
to you what display resolution is, and how to adjust the necessary settings. The amount
of information shown on your computer monitor is referred to as the “Display Resolution”
or just “Resolution”. The display resolution is determined by the number of individual
points of light called “pixels” aligned in horizontal rows and vertical columns used
to make the desired image. If your monitor was set to 1280 pixels horizontally by 720
pixels vertically, this standard HD resolution is called “720P”, there would be a total
of 921,600 pixels to make up one single frame on your computer display. The higher the resolution
the more densely packed together the pixels are in the monitor. Higher resolutions provide
a more crisp, sharp, and detailed image, but they also make everything appear smaller and
may be difficult to see for some individuals. Higher resolutions can be harder for your
computer to run smoothly. If you are experiencing slowdowns in games or video a lower resolution
may help alleviate the problem. Let’s start by setting a higher resolution. Close down
any open applications, if you have any, so you can see the desktop. Right-click on the
desktop and select “Screen Resolution” from the menu. The “Screen Resolution”
window will open. In the top of the screen you will see a representation of your monitor.
Next to Display” will list the type of display, in my case an “ULTRASCANP990”. If it lists
default or unknown there may be a problem that requires attention before going forward.
To change the resolution click to select the drop down next to “Resolution:”. The resulting
menu will list all the resolutions your monitor supports from low to high. We will change
the slider to a resolution of “1280 X 720”, and click the “Apply” button. You always
want to click “Apply” instead of “OK”, as if a problem arises and you have clicked
“Apply” it will revert back in 20 seconds. Click the “Keep Changes” button. Now it’s
time to set an appropriate refresh rate for your monitor. A big part of setting up screen
resolution, that is often overlooked, is making sure the appropriate “refresh rate” is
set for your monitor. If you have the big old heavy CRT monitors this is vitally important
to keep from straining your eyes. If you are using a new LCD monitor 60 Hz is default and
is usually fine. Click the “Advanced settings” link. This will open the advanced settings
properties window. Click the “Monitor” tab. Under “Monitor Settings” it says
“Screen refresh rate:”. You can see that it was set to “60 Hertz”, which is too
slow for a CRT monitor like what I have. A slow refresh rate will cause the screen image
to flicker and cause severe eye strain over time. Click the drop down menu and you will
see a list of all the refresh rates supported by your monitor. Select the “85 Hertz”
option, or whatever your highest option is. Click the “Apply” button. The “Display
Settings” window will open with the question “Do you want to keep these display settings?”.
Click the “Yes” button. Click the “OK” button to close the display properties window.
Now that we have the resolution set to a high enough level to provide a clear detailed image,
you might want to adjust the size of items on your screen to make them easier to read,
while still maintaining an optimal resolution. On the “Screen Resolution” window, click
the text link “Make text and other items larger or smaller”. This will open the appearance
and personalization display screen. Adjusting the settings here changes the size of icons,
text, and other items while still preserving the display resolution. Let’s make everything
a little bit larger by clicking to select the radio button next to “Medium – 125%”,
and click the “Apply” button. You will receive a new window stating “You must log
off your computer to apply these changes”. Click the “Log off now” button. Once it
logs you off log back into your computer. Now that we have logged back into our system
we can see that the size of the icons, the taskbar, the start menu, and window menus
are all larger, while the resolution is still the same.
