Output resolution is different from supported input resolution you need to check in the manual which resolutions are supported. the 1366x768 is the screen output or what it scales the supported resolutions to for the screen output. as eg: 480i low resolution gets scaled (to the best of it's ability) to the output resolution 1366x768. altho the scaling isn't smooth it displays all pixels. the more information the set recieves the better the scaling.

None are needed, Make sure the video input cable is properly
connected to the correct terminal, and that the
correct input mode is enabled. To illustrate,
when a VGA cable is connected to display a
computer screen, the PC input mode must be
enabled.

If it's not available on your PC, then find one that will work. You will need to look at the book for your TV to see what it does support and look for one in your PC that is in the list.

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.

Try increasing the screen resolution to maximum and colour quality to higher available. See whether proper driver has been loaded. If yes try reloading it and restart and check it

Does this card support dual screen mode? I just bought a monitor that I'd like to use with my HP Pavilion dv6t. I can't set the resolution higher than 1366 x 768. I am told that if the video card must...


Dual screen mode? You mean dual monitor mode?
But anyways, the maximum resolution that you can obtain on your Pavilion dv6t is 1366x768 unless you attach an external monitor. Even then, only the external monitor can go above 1366x768 resolution. You're laptop screen will remain at 1366x768 max.

Most likely this is a resolution issue. Set your computer's output resolution to one that is compatible with the TV, usually 1366x768 for a 720p Insignia TV. More info can be found here.

I have a s-video output and hooked it up though a cable to the yellow rca on the back of the tv. how do i get that to work and watch the computer screen on tv


1. This depends on the ports on your laptop and tv - if you have a vga port on your laptop then connect a cable to that and go to either the RGB or VGA on your TV. You can also get RGB to scart conectors so ther eare a lot of options! try your local Maplins for the cable (or look on eBay). Do a google image search to identify the connectors you have.

2. High-definition TV sets have several options of input ports and cable connections available. It's even possible to connect a computer to most HDTVs to get its picture quality. If your laptop computer is designed so it can plug into a standard computer monitor, you can easily plug it into an HDTV set, and you may have a number of options to connect it with. You must connect the video and audio separately in most cases. jQuery('.intro .thumbnail').each(function(i,e){ jQuery(e).find('img').one('error',function(){ jQuery(e).remove(); }); }); Difficulty: Moderately Easy Instructions Things You'll Need:
  • Laptop computer
  • HDTV set
  • Audio and video cables
  1. Step 1 Check the output ports on your laptop computer. There are three types of ports that can work with this connection: S-video (a circular port with pins in the middle), VGA (a square/trapezoid like port with pins in the middle and two screw pins on the sides) and DVI (a longer version of VGA).
  2. Step 2 Compare the ports on your computer with the input ports on your HDTV. DVI has the best quality, but not all TV sets will have these. Most HDTVs will have VGA and S-video (VGA has the best quality).
  3. Step 3 Connect the computer's output to the TV using the best cable connection that you have.
  4. Step 4 Connect the laptop's audio output to the TV's audio input that works with the video. In most cases, this requires a stereo-to-RCA cable, which has the single rounded plug with two black bands at one end and the red and white RCA plugs at the other.
  5. Step 5 Turn on the laptop and the computer and tune the TV to the correct input channel. Tune it to "Computer" only if you used the VGA connection; if you used S-video, tune the TV to that input channel.

I can't a full image on my toshiba 37RV25R


That's mighty vague of you. What input are you using? Is your source material's aspect ratio 16:9? There are a lot of things to consider. For some reason, though, I get the feeling that you're trying to hook the TV to your computer...

The maximum resolution supported by the TV's PC (15-pin D-sub) input is S-XGA (1280x1024 -- an aspect ratio of 5:4). The 37RV525R's native resolution is 1920x1080, though, an aspect ratio of 16:9. Obviously, you'll want to use a compatible (16:9) resolution. The TV would probably be happiest with 1280x720 @ 60Hz (a.k.a. "720p"). I've read that the TV will accept 1366x768 @ 60Hz but I'd just use 720p and call it done.

The differences between 1080p and 720p are barely discernible on a screen this size (especially if you're watching from across the room). No matter what input you're using, the source must have an aspect ratio of 16:9 or it will not be accurate and full-screen on the 37RV525R.

Can't get pc input to work


One thing you might want to try is altering the screen resolution on you laptop. If you are feeding the TV with a resolution higher than it can handle or in the wrong aspect ratio it is quite possible that it will not display a picture.

Magnavox 37MF337B/37 overscan only sometimes problem


This TV has a pixel resolution of 1366x768p

It will accept a 1920x1080i input from a high def source , but running a PC at 1920x1080i/p will cause the problems you describe, depending on what the PC is sending to the TV, because PC signals are not the same as high def.

Your PC should be set to a resolution as near to 1366x768 as possible. My PC allows 1280x768 and 1360x768. Try one of these for best results.

There are no settings on the TV to solve this problem.
