1The darkness of the screen is important. A darker screen provides better contrast and therefore a sharper picture will be seen. Take a good look at the screens in the store and ask the salesperson to shut off the television that is on display to really look at the screen.
Step2
Once you have a black screen, you can test for contrast ratio. This is a measure of how bright and dark a picture is at the same time. Basically it measure the sharpness of the image. Look for a higher contrast ratio for the best picture quality. Step3
Now look for pixelation problems. That is when you can see the small colored squares that make up the picture image. When shopping for LCD's make sure you are looking at models with high resolution to avoid pixelation. Step4
Color quality is another aspect to consider. If the subjects look unnatural and have reddish or lifeless tones, this cannot usually be fixed by adjusting the color scale and is an indicator of an LCD that is poor in picture in quality. Step5
If you notice light spots on the television this could be backlight bleeding. An LCD is backlit from behind by a several light sources. The LCD will block out the light that is not needed for the picture. When the light is not fully blacked out, it will "bleed" into the corner of the screen or even through the screen. You will see light spots and the screen will not look fully black. To avoid this, look for models that are not known for backlight bleeding
