Re: Using the TV as a vista computer monitor.

If you have connected to the TV via the DVI input, the TV should allow you to go to 1024x768.

S-Video, CVBS (composite) or scart connections will only allow 640x480 as these inputs are only standard def.

Element tv problems hook to computer get no signal

I'm assuming you are using this as an only monitor for the PC...
What resolution is the screen (max) and what are you trying to put into it? If the video output of the PC is too much it won't 'see' it sometimes... try lowering the PC resolution to that of the screen.

If it's a second monitor, you have to go into the screen settings on the PC and tell it to either 'mirror' (or duplicate) the existing monitor on it or extend the screen on another monitor.

Sorry I can't be more specific as I don't know what the screen or PC (computer) is...

Trying to connect computer to LCD TV and get no signal?


If you are trying to connect computer to LCD TV and get no signal, as a first thing do the following:

Double check cable and connection. If possible test different connections. Try using VGA, DVI or AV, depending on availability on computer and TV.

Ensure that Video drivers on computer are properly installed, and that the video adapter is working properly.

If you are using a laptop, ensure that you do not need to use a function button to enable the external display, this is pretty common on laptops.

If you are using a desktop, go to display properties, find the windows where you get the picture of two monitors, and ensure that both monitors are enabled.

On Vista try also using the 'Identify Monitor' button on Top. It is located on same properties panel as the two monitor, the main Display Property windows. From the same window you can also modify display resolution, as explained later.


If still no luck, then it may be a problem of synchronization between TV and computer, in that case try the following.

  1. Turn off TV.
  2. Disconnect TV power cord.
  3. Restart computer.
  4. With Computer already on, plug back and restart TV.

....If that does not work.

On computer, go to display properties.

First try changing computer resolution. The TV max resolution may not be available on computer. In that case try lowering down to the smallest 16:9 resolution available on computer graphic settings (usually LCD TVs are 16:9), and if that does not work, set resolution to 800x600, just to test (picture proportion will be distorted, or you get squared box on a 16:9 TV).

If that does not work, open Display Properties. In Display Properties access Advanced, and then Monitor settings (XP). On Vista choose Personalize in control panel, then Display Settings, and go straight to Monitor Settings, in there again go to Advanced.

Under the advanced monitor settings you will find a tab called monitor, in there you find the monitor frequency. Try setting this to 50Hz, if that does not work try 100 HZ, that is the output frequency of your TV. If you get unsupported frequency, revert value to normal.

I hook up my pc to lg lcd it always says invalid format any solution

What cable connection are you using? What resolution was the computer sending to the video graphics adapter before you connected the two?

The TV can only support
VGA Resolution: 720x400, 1360x768, 640x350, 640x480, 800x600, 1024x768, 1280x768, 1360x768 or 1366x768
HDMI to DVI: 640x350, 640x480, 800x600, 1024x768, 1280x768, 1360x768 or 1366x768

For best results you should use 1360x768.

Try resetting this when the Input is set to that for the computer. Press Menu and select Picture. Press Enter and select Screen (RGB-PC) (use the Up/Down arrows). Press Enter and select Resolution. Then press Enter and select the desired resolution. Then press Enter again.

If you like there is a Auot-config option in the Screen menu, that may set the TV properly.

If the above doesn't help, use another monitor and check the output resolution and then reconnect to the TV.

I hope this helps.

to adjust the monitors resolution. Right click on the desktop in an open area not on a icon.> select properties or personalize. depending on the operating system> then click on the settings tab on top> under the screen resolution you will find a slider bar. > try sliding it over to the left a couple notches. This should resolve the issue!

I tried to connect my PC to the TV, but it said the mode was not match. How the PC fits it?

You need to adjust the resolution settings of your computer. This information was found on the Dynex website: ( in the frequently asked questions section on page 9. To adjust the resolution on Windows Vista: 1.Click the Windows icon to open the Start menu. 2.Select and click on Control Panel. 3.Click on Appearance and Themes. 4.Click Personalization. 5.Click Display Settings. 6.Select Monitor 2. 7.Drag the screen resolution slider to the left to decrease the resolution of your monitor, making text and pictures appear larger or drag the slider to the right to increase the resolution of your monitor, making text and pictures appear smaller. 8.Click Apply to have the new resolution take effect. 9.If the Monitor Settings dialog box appears, look at your display. If you like the new resolution, click Yes. If you do not like the resolution, click No and adjust the resolution using the screen resolution slider. 10.Click OK. If this solution does not work for you .You can copy the above web address and paste it into your address bar. There you will find the support section. You can use the support e-mail to talk to the customer support people about the problem you are having connecting your computer to the television.You can also call the customer support at this telephone number 1-800-305-2204 between the hours of 7am and 12 am CST. Give them the model number of you television and tell about your problem. I hope this information helps you with your problem.

Connecting laptop to lcd

You may need to use the S-video cable for video. Make sure video mirroring is disabled on the powerbook. Also, make the external monitor the primary display by dragging the menu bar to it in Displays preferences (Mac OS X) or the Monitors control panel (Mac OS 8 and 9).

Invalid format message when trying to use the RGB(PC) port

Honestly, that sounds like one of two things happened. Either the resolution of your computer video card changed or (I'm not sure with your specific TV) the TV's resolution changed.
If through the TV menus you can adjust PC resolution, I would try changing the resolutions. In the LG 47LB5DF TV, press Menu, then go to Picture, then go down to Screen. On the screen menu, you will see Resolution, Position, Size, Phase, and Reset. First try adjusting the Resolution to some of the options you see. If that doesn't work, try to reset the screen settings.
If adjusting those settings on your TV does not help, then you will have to change the resolution through the computer. Try connecting a monitor to the computer. If you get a picture through the monitor, on the desktop right click and select Properties. If using XP go to the setting tab, if using Vista/7, select Display Settings. Lower the resolution to something you think the TV will be able to handle, then connect the PC to the TV again. If you are using an HDMI connection to the TV, you may have to turn off the computer, connect the cable, then turn the computer back on with the TV on the correct input.
If the monitor doesn't show the picture or if you don't have another monitor, you can try adjusting the picture in safe mode, by pressing F8 after you press the power button, before you see the Windows loading screen. Press if multiple times if necessary. You should see a screen that gives you a few startup options. Select Safe Mode. After Windows boots up, you should still see the screen as the resolution would have been reduced. From there try changing your display settings.
Hopefully that info has helped. I noticed that you asked this question 2yrs ago, so I hope you have already figured out how to fix your problem. I simply wished to post this in case it would help you or anyone else had a similar problem. Good luck and take care.

VGA hookup to my Toshiba Satellite

Set the TV input to PC (that's ViewSonic's term for the VGA port).

Setting the computer to output to the PC may depend on your OS (XP, Vista). Reboot the computer after connecting the monitor and see if new hardware is found. Reboot again if you have a flickering screen. In Vista, right clicking on the desktop brings up various video and desktop options. Choose Screen Resolution and look for the multiple monitors line. Click Apply and OK after setting your desired output. In the Screen Resolution window you should see two monitor boxes (labeled 1 and 2) if the computer sees the monitor.

If the second monitor is not showing up (no new hardware found), check your BIOS and device drivers to see if you need to enable or update the drivers for the VGA port. Check your manual for the BIOS (often it is click F1 or F2 before the OS loads; it's often tricky timing and I have to try repeatedly). Device manager will have a red x if the port is disabled; the exclamation point (yellow triangle) indicates driver issues.

I realize this is nearly a year after you posted your questions but I hope it will help the next person searching for answers on this TV.

Pc and lcd tv

that's really easy. just plug in a VGA or DVI cord from the PC to the Sova TV (those are both regular cables that normally would go the computer monitor). then press the source button on the remote (not too fast, it takes a second to detect the signal), until you see VGA or DVI, and your computer screen should show up. use the display settings on your computer to get the best resolution on the tv. depending on your computer, you may have a program that can save different screen resolution profiles for you (since the Sova TV resolution and the computer's optimized resolution using a different screen (such as the built in screen on a laptop -- or a different monitor with better resolution than the Sova TV), this way you can easily toggle between settings depending on what monitor you use.
