Currently most of people using lcd than ever cause it not expensive and have various model, size and brand to serve your need and it save your area and save energy than CRT.
Only problem of lcd is "dead pixel, bad pixel or hot pixel". Yes if you're using notebook or laptop you risk to encounter this problem too, this is an important point you should notice before decide to buy new lcd monitor or new notebook/laptop.
Dead pixels, bad pixels and hot pixels are difficult to see with naked eyes, i recommend you to test it before bring it back to your home.
DPT or Dead Pixel Tester is one of good application for buying lcd monitor and notebook/laptop, its interface looks like picture above, why i recommend it?, It's a small program just 222KB, don't need to install on computer to use it that mean you can save it into your flashdrive and keep it with you, can test any lcd anywhere just put it in usb port and run it from your flashdrive, it easy to use just click button on your mouse you can see how to use it when you run this program(can you see buttons in red, green, blue on above picture) so just try it and you will can use it.
When you click mouse's buttons, DPT will change your lcd's desktop color or pattern depend on what button is clicked, the most difficult of using this application is you have to find dead pixels, bad pixels and hot pixels yourself, but it worth to use time to carefully see your lcd or notebook before bring it home than bring it back to claim or worst case if you see these bad pixels on lcd or notebook when it out of warranty.
You can download Dead Pixel Tester here or go to www.dataproductservices.com, it's a freeware.
Next time before going to buy new notebook/laptop or lcd, don't forget to bring DPT with you.
