Setting screen resolution and colours

The graphics card in your computer controls the resolution and number of colours that you see on the screen (monitor). Many computers are delivered with the resolution and colour settings inappropriate for the software that users wish to run so its a good idea to 'take control' and make these adjustments yourself. 

Screen Resolution

Resolution on a computer monitor is measured in pixels. The word is short for 'picture element', a dot on the screen. The table below shows some common settings for screen resolution.

Not only can resolution be controlled, so too can the number of colours displayed. The number of colours can range from 16 to what is called 'high colour' (32 bit - millions) of colours. The upper limit is controlled by the quality of the graphic card in your computer and the amount of memory installed on the card.

Certainly, if you intend to use programs such as Adobe PhotoShop, Microsoft Publisher, IntelliCAD and Autodesk's AutoCAD, you need to spend a little time making sure that the graphics settings are correct (and appropriate).  We recommend setting screen resolution to 1024 x 768 using at least 16 million colours.

Adjusting screen resolution

Click here to play a movie showing you how to set resolution and screen colours. Warning: the file is 19 Mb in size, so it will take some time to download.

It is useful to play the movie 'full screen', rather than in a window. To ensure that the movie player runs full screen, press the ALT & Enter keys simultaneously. 

The sound level may vary from computer to computer. You can increase or decrease the sound level with the up and down keys on the keyboard.

Monitor

We recommend that you buy a good quality 17 inch monitor. Money spent on a quality monitor is money well spent. Make sure that you keep the surface of the monitor screen clean.
