Connection for cable box to tv monitor

No because it is a monitor only; meaning it does not have a TV tuner of its own.

Hi,
Samsung SyncMaster 2233BW does not support TV / Cable input (RF Connector).
If you wish to connect Cable to the LCD, you have to buy a TV Box and connect Cable with your LCD through TV Box. (Cable TV to TV BOX and from TV BOX to LCD)

Hope it helps! Good Luck! Thanks for using Fixya!

Your setup has a TV/Monitor and a audio/video box. The A/V box is connected to the TV and other source inputs connect to the A/V box. Hookup your cable box to the A/V box either using component video (green, blue, red) RCA cables from cable box outputs to the A/V box inputs OR the A/V box also has a DVI/HDMI input jack which may work using a HDMI cable.
Select the proper source.

If you are connected to a high definition cable box or satellite tv box you would not need to turn to channel 3 on your television. The television would need to be in the right input either component or hdmi. If someone connected the tv to the cable box or satellite tv box with a coax cable like an antenna cable then the tv channels will be available on channel 3 as well but they will not display in high definition. You change channels with the cable box/satellite tv box remote control. If the above is not correct and you are only connected to an antenna cable and not to a cable box or satellite tv box you will need to complete a channel search from the tv menu. It sounds like you are using a cable box/satellite tv box and that the tv is on the wrong input. If the cable box/satellite tv box is not working (i.e. just a black screen) on your television than that is a different matter entirely.

you are trying to use a monitor as a tv, you will need a tuner to get a pic, use a cable box or digital to analog tuner to get something

It all depends on what your cable box output is.

This monitor appears to support a standard cable cord input. So in essence all you should have to do is connect a cable cord from your box to your monitor.

The cable box IS an external tuner.  You should connect the video output (either S video, HDMI, or component video) of the cable box to the video input of the DVD.  Then connect the audio output of the cable box to the audio input of the DVD via stereo RCA cables.  If your tv monitor has multiple inputs (ie: video 1, 2, and 3...) connect the video and audio output of the DVD to your tv monitor using an alternate video input (if cable box goes into your tv thru video 1, connect the DVD to video 2).  If your cable box only has one output, or your tv has only one input, then just connect your cable box to the DVD as above, and connect the DVD to your tv.

The cable box is probably outputting a resolution the monitor is not compatible with. Computer monitor and television resolutions are usually different, and not cross compatible in some cases.

For example, wide screen monitors are usually 16:10 aspect ratio, while TV is usually 16:9 aspect.

The AL2216wbd is a 1680x1050 display, while HD TV is either 720p (1280x720) or 1080i (1920x1080).

If your cable box is set to 1080i that would be too high for the monitor. You will need to set it to output at 720p, and even then you will probably get a vertically stretched picture since the monitor has a taller aspect.

I would suggest getting a pc tv tuner card. http://www.newegg.com/Product/Product.aspx?Item=N82E16814122221 Then you connect your cable wire from the cable box into the pc and watch it that way.
