Picture quality is not as good as viewed at the store
View the BRAVIA Image available on your TV to confirm picture quality. BRAVIA image
is sample image available by default on your BRAVIA.
For R Series
Press the HOME button, and then go to Media > Photo to view sample image.
If BRAVIA image is clear →no issue with
your TV, most likely this is because of the
content quality. Refer to page 5 for more
details.
If BRAVIA image is not clear → service may
be required. Please consult to Sony Contact
Centre.
For W Series TV
Now you can run Problem Diagnosis to troubleshoot Picture/Sound symptoms.
Press the HOME button, and then select Help → Customer Support → Problem
Diagnosis → Picture/Sound Symptoms.

cause.

Display/Picture

Standard Definition (SD) and High Definition (HD)
Standard Definition (SD) has a vertical resolution between 480 and 576 lines.
High Definition (SD) has a vertical resolution between 720 and 1080 lines (Full HD).
When SD video signal is displayed on HD TV, the image will either appear smaller on
or up-scaled (resized) to fit the screen.
Some DTH or set-top box (depends on the providers) may upscale SD signal to HD
levels. However, this can erode the quality of the pictures or even crop the image. For
example, 4:3 image can be up-scaled and then cropped to display full screen image on
16:9.
Tips:
HD TV channels require you to have a
special set-top box that receives HD signals
and routes the content to the TV via an
HDMI cable.

Up-scaled SD videos on HDTV
