I suspect the TV is unable to use the Horizonal and Vertical scan frequencies put out by your computer.

Samsung TV Is Not Picking Up A Playstation 3 HDMI Signal


If you are able to connect your PS3 to another TV using the same HDMI cable that would rule out your PS3, if it works.....or
does the PS3 itself have any settings that perhaps need to be set to an HDMI output as opposed to Composite or SCART etc?
Also have a look at the HDMI settings in theh TV menu too.

Hdmi laptop to tv


I'm assuming you wish to connect the laptop to the TV.

first off connect the HDMI to the laptop and the TV and then change the source to the correct one for what HDMI port you chose so if the wire is in HDMI2 then switch to HDMI2.

next how to make it use the TV so go to the desktop right click and go screen resolution if it has picked it up it will be in the drop down menu then its just a case of resizing until it looks right

How do I connect a laptop to this tv?


It will depend on the laptop's available external video ports. You can connect a VGA cable from some laptops to the VGA port on the TV. Then plug in a 3.5 mm audio cable from the headphone jack to the PC audio in port. (The audio connection is optional. You could continue using the laptop's speakers.)

Make the connections with the TV and the laptop off. You may need to enter the BIOS to enable the external video port. (It can be turned off to save power. The BIOS is accessed on boot by pressing a key (Esc, F1, Del) noted on the splash screen. For Win8 machines, you'll need to do a special restart.) Then turn on the TV before turning on the computer. The TV monitor should be automatically recognized for resolution and refresh rate. Next, if you have a Windows system, right click on the desktop (pick a spot with no icons or running programs). Click on Screen Resolution (or perhaps Graphics Properties, depending on the OS). Set the monitor to duplicate the screens or send data only to the TV screen.

I'm not sure if the HDMI ports will understand a computer signal. (Not all TVs can interpret the computer's HDMI signal; it is different than that of other set top boxes.) You can try the following connections.
If your laptop has a DVI output, use a DVI to HDMI cable (or adapter) to connect to the TV. Then connect the HDMI cable to HDMI 1 and use the PC audio connection as above.
For an HDMI output, use an HDMI cable. (You will still need the audio cable unless you can reset the audio signal to output on the HDMI port. Go to the Control Panel and then the Hardware and Sounds section. Under Sound, select Manage audio devices. Then in the Playback tab, make the HDMI audio the default.) For Display Port or Thunderbolt outputs on the laptop, you will need a DP to HDMI adapter.

If the HDMI port doesn't understand the computer signal, you'll need to use a converter to go from the computer's output to component video or to VGA. Then connect the converter's output to the appropriate port on the TV.

I hope this helps.

Tv not picking up hdmi input


HDMI is goofy. Connect everything while it is off and then power everything up. That should take care of it after the first time you do it.

Hello there. I might be able to help you here. Go to your desktop right click and go to resolution settings. Make sure you have your tv selected on your pc as the display you want to use. This may solve your problem.
