Standard screen format televisions (4:3, the aspect ratio of the screen width to height) are primarily designed to
view standard format full-motion video. The images displayed on them should primarily be in the standard 4:3 ratio
format and constantly moving. Displaying stationary graphics and images on screen, such as the dark top and bot-
tom letterbox bars (wide screen pictures), should be limited to no more than 15% of the total television viewing per
week.

Wide screen format televisions (16:9, the aspect ratio of the screen width to height) are primarily designed to view
wide screen format full-motion video. The images displayed on them should primarily be in the wide screen 16:9
ratio format, or expanded to fill the screen if your model offers this feature, and constantly moving. Displaying sta-
tionary graphics and images on screen, such as the dark side-bars on non-expanded standard format television
video and programming, should be limited to no more than 15% of the total television viewing per week.

Additionally, viewing other stationary images and text such as stock market reports, video game displays, station
logos, web sites or computer graphics and patterns, should be limited as described above for all televisions.
Displaying any stationary images that exceed the above guidelines can cause uneven aging of picture tubes (CRTs)
that leave subtle, but permanent burned-in ghost images in the television picture. To avoid this, vary the program-
ming and images, and primarily display full screen moving images, not stationary patterns or dark bars. On televi-
sion models that offer picture sizing features, use these controls to view the different formats as a full screen picture.

Be careful in the selection and duration of television formats used for viewing. Uneven CRT aging as a result of for-
mat selection and use, as well as other burned-in images, is not covered by your Samsung limited warranty.
