I have a samsung LN32A450. When I connect my laptop to to it via the vga port the tv doesn't recognize it. I tried different resolutions and two different laptops: compaq Evo 180 & IBM ThinkPad. I know that the laptops vga outputs are functioning properly as i tested the same settings on a SONY Bravia KDL-32M3000. Thanks in advance.

well are you using a blue vga cable? if so after you hook it the cable up on both the tv and computer you need to switch the TV input to vga and then after that in some cases you need to change the computer settings to turn on remote monitors tell us more about the computer and what operating system you have then we can assist you further
Nov 20, 2013 - Q: Can I connect the TV to the PC via a VGA cable...bearing in mind the .... Forum; SolvedI'm trying to connect my Sony bluray player home ...
Are you using the VGA port on the Jensen TV? What is your computer's OS?
The usual reason for the unsupported mode message is that the the computer did not recognize the TV as a monitor on boot up or that the previous settings were incompatible with the TV. (For example, if you previously had a CRT connected to the computer and used a refresh rate of 75 Hz, the TV can't handle the refresh rate. It needs to be set at 60 Hz.)
First turn off both the TV and the computer. Then turn on the TV and set it for the PC input (assuming you are using the VGA port). Next turn on the computer. If you have Windows XP or later, it should find the TV and set the resolution without any input. (If it doesn't, use a different monitor and set the resolution to 1366 x 768 and 60 Hz. Then try again.) If you used the HDMI port, try the VGA port. This TV doesn't understand a computer signal over the HDMI port (only set top boxes).
Look for a button on the remote or the TV itself labeled Source or Input. This should let you change the input between TV, AV, HDMI (on some TVs), and PC. Just press the button repeatedly or use the up/down arrows.
Before setting the input to PC (VGA), turn off the TV and the computer. Then connect the VGA cable (M-M) and the audio cable (a 3.5 mm M/M cable, if you plan to use the TV speakers) between the two units. Next turn on the TV and set the input to VGA. Then turn on the computer. (This is if you are using the VGA or D Sub 15 connection.) For a desktop, if you do not have another monitor connected, the TV should automatically be detected and the resolution set with any Windows OS (XP and later). However, you may need to reset the resolution and the refresh rate. For Windows 7, right click on the display and choose Screen Resolution.
For a laptop, you may need to enable the video port in the BIOS. Accessing this depends on the manufacturer of the computer motherboard. (Often Esc, F1 or F2 is the key to press after turning on the computer but before the OS loads. This can be tricky to time correctly.)
With a laptop or a desktop with another monitor attached, you will need to tell the computer how to deal with the multiple monitors. (Extend, monitor 1 only (or laptop internal monitor), monitor 2 only (external monitor), or dual display.) For my HP laptop with Win7, I choose Graphics Properties instead of Screen Resolution. There may be a keyboard Fn shortcut to access this.
Some TVs will accept a PC signal on the HDMI port (directly from an HDMI port on the computer or via a DVI to HDMI cable). Not all TVs do this. (Without the model for your TV, I can't confirm if this will work. If it doesn't, it is because of the differences between the PC output signal and that of set top boxes (cable or blu-ray players).
Check your laptop with the same VGA cord on some projector or a monitor. If it works there, then there is a problem with your TV's VGA switching circuit. If it does not work, then there is problem with either the VGA cord or laptop's VGA port. To rule out the possibility VGA cord , replace it with new one. Please give the feedback for this so that further diagnosis can be done, if you are comfortable with the TV's electronics.
the native res. for the TV is 1680 x 1024. you may want to try a different resolution like 800 x 600 or 1024 x 768. not the native resolution of the laptop.
I had the same problem with my Samsung series 6 32" Lcd. After many hours of trying different settings and banging my head on the wall I found the solution. What the problem is your VGA cable not supporting the high resilotion of your Samsung TV. The simple solution is to buy a new VGA cable that supports HD. Take a look at this site you need something like this one! Hope this helps.....C
If it is, then yeah you should be able to output VGA from a PC to the TV with a proper cable.
However if the TV has DVI or HDMI connections on it, it's better for
you to connect it that way. DVI/HDMI is a digital signal and if it's a
digital-based display tech TV, then you're better off using that. Also
if the TV does resolution above 1360x768 (i.e. if it does 1080p) you
can get higher resolution by going via DVI/HDMI...
The resolution and refresh rates have to match exactly to the TV for it to work correctly with the computer.
The newer computers are using much faster refresh rates by default. Their default resolution is also different.
Consult the manual for the TV and see if the computer's external monitor output can be set to match to what the TV exactly requires. Both the refresh rate and resolution are critical.
