Samsung connection problems

Davy

Getting "mode not supported" when i connect PC to tv. the manual says to check resolution and the freq of video adapter but i have them set right...

bit new to this, so any help

Homer

Bit more info might help solve it? How are you connecting the PC/Laptop to the LCD??
VGA? DVi?
What resolution does the TV support? 1024x768 or higher? Does the resolution on your PC match this? Refresh rate set the same?
I'm sure it's something small but need a bit more info.

Davy

yes its vga connected. Yes have the res on max and freq set to 60hz. Tv says no signal without vga connection and then when i connect it it goes to not supported.

Homer

Res set to max on what, TV or PC?
I would guess the resolution is set too high for your TV but again i'm guessing??
What's the make and model of the TV?
What resolution do you have the PC set to?
We'll get there...!

Davy

not at home to check what resolution exactly but pretty sure its 1268 approx, the one after 1028 anyway. The tv is samsung 32m88.....or something... To that effect. Just not at home to be exact. Would be thinking those settings would be ok...?

Homer

Well check the model number when you get home but if it's any of the newer model samsung 32's it should support up to 1366*768 so check and see if your PC is matching that. A lower resolution setting should still work I would have thought just given you a lower resolution pic? A higher resolution might not display?

Davy

PC is set to 1280x1028 which is max. the tv supports up to 1360x768 thats its optimum setting stated in the manual.

This comes up a lot so your not alone , if at all possible connecting the pc using a DVI to HDMI cable is recommended as you wont come across this type of issue ,

For the TV's VGA PC input try the following ,

The PC should be set to the same native resolution of the TV , in this case that would be 1366 x 768 , however , perversely , some " PC inputs " on TVs have a limit on the resolutions it will accept , with some of them insisting on a 1024 x 768 max resolution , check your manual for the resolutions listed on that input.

To put another mine in the minefield , some graphics cards will only output certain resolutions on the TV output port , with some cards only having 3 outputs available , these are usually SD and the 2 high definition resolutions , which are 1280 x 720 and 1920 x 1080. This has been known to cause endless problems with some plasmas , as they have a 1024 x 768 resolution , something most graphic card TV outputs dont have ( except the latest ).

To avoid most of the above , connect using the DVI on the PC to the HDMI on the TV , no matter how bad the res match here , it will show on the TV and let you adjust for the best picture.

dont have a dvi port

So is it a laptop your connecting then ? If so have you pressed all the right key combinations for the external display to be active ...its usually Fn plus some key ?

If its not a laptop and the PC only has VGA then I stongly recommend getting a new graphics card , these can be had very cheap these days , an Nvidia 8500 or 8600 , or an ati 2400 or 2600 would be the preferred choice for any kind of HTPC as they can be got with passive cooling and in some cases with HDMI.

Those tv's usually have several different resolutions that are supported, and you usually have to get them exactly right to have it sync.

OK , post the model of your PC , lets determine first if you have a PCI express slot , also post the OS you are using , is it XP , Vista or whatever.

Then , decide on the card you want and I'll post how to change it , its a piece of cake , should be no problem , but like I said , post the model of your PC and the OS.

Dim 4600 on Xp, cheers.

Would a VGA to Three Components Video Cable work instead? the thing is optimum res is 720 mode while max is 1080

Thats highly unlikely , component comes in different formats , the one asscociated with VGA is RGB or Red green blue , the one on your TV is most likely Y Pb/Cb Pr/Cr , and these two are not compatible.

Your connectors for this are most likely coloured Reg green and blue but that does not mean it takes an RGB input.

The Graphics on a Dell dimension 4600 are AGP as far as I can determine , the cheapest AGP I can find that will do the job is here ,

Though if you want to spend more money there is a version with HDMI out on that site too.

Changing a graphics card is simple , just uplug the PC from everything , open the side of the box , and look for the graphics card , this will of course be the card with the video connector on it , and it will be offset from the rest of the slots , the AGP slot is brown and slightly to the side of the other ( PCI ) slots.

Remove the screw in the end plate of the card , push back the plastic retainer on the other end of the card and gently pull the card out of its slot.

Then place the new card in the same slot doing the reverse to put in the card.Dont forget to put the screw back in. Put the cover back on and boot up , the machine will detect the new card and install a basic set of drivers for boot up.
As soon as you are back in the XP desktop , insert your driver disk that came with the card , or better still download the latest drivers from ATI or Nvidia , and install those , and your done.
