Set up TV as monitor for laptop with Fedora

James if the laptop was powered on when trying to connect to the Emerson tv you might want to release the power from the capacitors on both the laptop along with the TV; simply by unplugging both power sources for at least 30-60 secs then reboot and make sure to have the VGA back connected when booting .

Hi,
Usually you need to connect your LCD TV to the laptop and then restart your laptop and in the meantime keep the TV on. It will recognize it automatically.
if this didn't work you need to go to the graphic card setting by Righ-Click on your desktop background > Properties > Settings
and make the right setup.

Assuming a Windows OS, right click on your desktop (any place without an icon). Alternatively, use the Control Panel to get to the Display Properties. Go to the Settings tab in the Display Properties window. There you should find all the monitors available listed. Your TV will probably be listed as an inactive monitor. You need to make it an active monitor and probably will need to reboot before the computer can use the new monitor.

Also make sure that the TV has been set to see the picture sent from the computer. (Scrolling through the list of picture sources can be an issue.)

I hope this helps.

This means the monitor believes it's not connected to the computer. Verify the cables first of all. Then try booting in safe mode (F8 key at PC startup) in order to verify that the PC is sending data to the proper video port (you might have a dual VGA / Digital output, for example, and the monitor might be connected to the wrong PC port). Quite often, a "bad signal" will be the same of "no signal"; and you can have a bad signal if the monitor resolution on the PC is set too high. This could happen if you installed a high-resolution capable monitor, and then replaced it with a not-completely-plug-and-play, lower resolution one. The PC would keep sending hi-res signals to a monitor which can neither interpret them, nor tell the PC "please slow down". To check this last possibility, reboot your computer while the monitor is ON. When PCs reboot, they usually drop back to standard VGA signaling, which all monitors understand. If the monitor abruptly comes to life and displays a boot screen, then goes No Signal again after several seconds, you've got a resolution issue; get in Safe Mode with F8 key at boot, and modify the screen properties (right-mouse button on the desktop, then Properties).

If everything else fails, try also connecting the monitor to another PC or laptop, to see if it works there.

Possibly, the CRT monitor was set to a frequency which is too high for the LCD monitor.

Try booting in Safe Mode (press F8 at boot), then set the video for a lower resolution.

Reboot with the new, lower, resolution.

In Control Panel choose Hardware, then Scan for New Hardware and get the LCD monitor recognized.

Then, from the Desktop properties, you will be able to see all resolutions supported by the monitor.

replace the cable and make sure in your vizio owners manual you are using the right cable.all lcd tvs can be connected to your
laptop.

Yes weak signal. Also closing the laptop lid puts the computer in sleep mode.

Go into your control panel. Select display. There will be a picture showing 2 screens. Select the 2nd screen, and lower resolution to it's minimum. Apply and test. Slowly increase till you find what your happiest with. Worked for me using a ASUS laptop and LG60'plasma.

The simple patch that I found (same problem) was to start by using any old monitor that I could borrow to set up my Dell Laptop.
After getting the Laptop booted on a regular monitor I right clicked on the desktop and went to properties then to the settings tab.
Here I found the dual monitor settings (#2 will usually be dis-abled by default.)
Click on #2 monitor and set the resolution to the lowest number (800 x 600 works well)
Then I clicked on "make this monitor my primary monitor"
As soon as I clicked apply the PC Windows screen appeared on the Polaroid TV screen

Earlier I had set the secondary monitor as "extend this screen to this monitor"
This also worked but I had to "drag the current screen to the right all the way off the
"borrowed monitor" until it appeared on the TV screen. The mouse pointer will be there also.
At first it took a little getting used to but in a few minutes I was up and running.
Hope this helps your situation
