Question about Televison & Video
We connected the samsung to a box from gektv and we saw an option to change the settings to 1080p so after we chose that option the tv screen showed us no signal, then said searching for signals, and the gektv was kind of showing up but it was distorted. Later it showed something like a download bar that was searching for new devices after it was done it said it didn't find anything....how can i fix this?

You may not necessarily have anything incorrectly set up, but there are a couple of things that I would suggest trying.
First, you'll want to make sure that your TV is set to the correct input source. Some TV's will require that the input source be changed in order to display any signals from an external device, like your HD-DVR. This can typically be done by accessing the main video menu using your remote control.
According to information provided by the manufacturer, you should be able to change the input source for this model TV (Samsung LN46A750) by doing the following:
* Press the "Menu" button on your remote control
* Press the "Up" or "Down" arrow button to select "Input," then press "Enter"
* Press "Enter" to edit the "Source List"
* Highlight the signal source for the HD-DVR, and press "Enter"
Next, you may want to try updating the TV's firmware. In some instances, simply updating a TV's programming can eliminate any potential hardware or software conflicts between two devices. To update the TV's firmware you will need access to a computer and a USB flash drive. Step-by-step instructions and the firmware update itself are available through the following website:
Make sure to read all the warnings and disclaimers available though, as your TV may already have a more up-to-date firmware version than the one that can be obtained through Samsung's support page.
Should neither of these address the issue, you may wish to see if connecting your HD-DVR to a different HDMI input solves the problem. Much like computers, TV's have been occasionally known to have faulty inputs or loose internal connections.
If all else fails, I’d suggest contacting the manufacturer for further assistance. In many cases manufacturers are able to provide over-the-phone troubleshooting support, in addition to having access to a wider variety of possible remedies for hardware problems.
Hope this helps you out.
Go Ahead. Use Us.

With an HDMI cable connected, the cable box determines the picture size. The settings on the cable box must be changed in order for you to get the correct picture size. I have some experience with Motorola cable boxes; usually to access the settings you turn the box OFF and then press the menu or settings button on the box to bring up the display menu. Hope this helps!

First of all, check that the TV is set on PC input when you use PC video input at the back.
Then you may also need to go to video and display properties>>settings, from control panel (personalize on Vista).
There lower down resolution and ensure that frequency is set the same as tv.

SOURCE: displays weak or no signal
To get any HDTV to work this is what you have to do;
1) Connect your antenna cable which you have done.
2) Go into the menu to the source option and select AIR/ANTENNA since you are using an antenna.
3) In the menu you will have to SCAN in the stations. This auto program will find all available stations.
Now you can watch tv by selecting the station you want.
The new generation of HDTV is different from the old analog sets. These have to be set up to work.
Exact information can be found in your Users Manual.
