Black image on Itouch screen

Movies that are created for "Wide Screen" viewing show up in letterbox on your TV. If you go to a theatre you notice it is a big rectangle. To be able to fit all of the widescreen movie on a TV it has to make the height smaller.


Because many people want to see the "complete" Movie, the "Letterbox Format" came about. I do NOT know what the word "Letterbox" actually means, or how that term was chosen. To get the complete Rectangle into that Square, they discovered that they could shrink the entire rectangle to fit that square. Meaning, what used to take 2 inches on your screen, now may only take 1.75 inches. Now a problem arrose. When you shrink the WIDTH to fit your dinky Square of a TV, the HEIGHT also has to be shrunk along with it, or else you're stretching the image as if it was on silly-putty ("Compression"). When the image was shrunk to fit the TV Screen, they were left with a gap at the top and bottom of the screen. So they simply fill it in with "Black". I guess the only alternative was to leave it snowy.

Set Input/output to MathIO.
Press the Integrate key, to the right of CALC.
The image of integral appears with a rectangle for the function, and two small squares (one for the upper limit the other for the lower limit).



Type in the integrand (the expression you want to integrate) in the bigger (on your display) rectangle. Use appropriate parenthesis. To type in X press [ALPHA] )
Use the down arrow to move cursor to the square for the lower limit. Type in the lower limit. Use the Up arrow to move cursor to the upper limit square. enter the upper limit. Press [=] key. If you did not make mistakes, and your expression is not too complicated you should get your integral.



Note: The screen captures are not from a Casio FX991ES. But that should not matter to you.

The closed caption function is ON with your TV now. Make it OFF.

Tv still have Close Captioning functions is on.Tries tv remote button like CC turn off all CC1,2,3 to all off.Or goto tv menu goto Close Captioning turn off all CC1,2,3 or Text 1,2,3 to all off.Should stop the rectangle square appearing.

Just use your remote or the tv menu to turn off closed captioning.

It would be "cheating" for anybody to do your "homework" from your computer-mathematics class, unless you submit your answer, saying that an EXPERT on FIXYA did all the work on your behalf.

Turn the device off( from the back button) press volume up and the flag button( third from the right) in the same time and power on the device. Keep pressed the two buttons untill a screen shows . Press ok and then another ok. Then restart the device. This will do it

captioning on turn off with remote.

I could not see the image you say you included in your description. If the rectangle is black (and not just an outline) it may be the box associated with captioning or text descriptions. Use your setup menu or remote control to turn captioning/text off.

I'm not sure what type of TV you are using,, but most all Large Screens have a reset button someplace. You should be able to reset the TV and fix the problem. Its not the remote, making the image appear, but a command from it was misinterpeted. Sometimes turning the set off will work, but most often it needs to be reset.

EXCEPTION... if you are using a cable box. Disconnect it from power, wait 1 minute and then see if the problem exists. If the cable box is on even with the DVD you may still have this issue. Please reset the cable, and if that doesn't work, reset the TV.
Thanks! //D
