Connecting Laptop with LCD TV

Hi All

whats the best way in terms of picture quality to connect a laptop to an LCD TV?

I connected it just with an S Video to S Video, and I see room for improvement, maybe with a different type of connection?

Erm think you can connect through VGA? Not 100% though!

My LCD does have a VGA slot, but where would it come from my laptop?

Also for you experienced users, I have to set me laptop to 800 x 600 reso to be able to view a film.

All the players, VLC, power DVD and WMP show a blank screen on my usual 1024 x 768 reso, but I can see the film playing on my laptop.

How can I leave my laptop set as 1024 x 768 and still be able to view a film on the LCD? I can see everything else, its only where I play a video file when the blank window comes up.

Firstly what TV and laptop are you trying to connect? It's very rare for a laptop to not have a VGA port, it should look like this (on both laptop and TV):

Alternatively you may have a DVI port, it's a large white port which looks like this:

If that's the case, you either need a DVI->VGA connector which is easy enough or a DVI->HDMI if your TV supports HDMI.

As for your resolution question, this sounds like an issue with the primary overlay - in Windows, the primary display is hardware accelerated which means anything which uses the primary overlay (like playing a film) will not work on a secondary display. The easiest solution if you don't need both screens on at once is to use your laptops built in display switch - you should be able to hold Fn on the bottom left and press one of the function keys to do this. Look for something like CRT/LCD, or a picture representing a monitor - again most laptops support this.

Check your refresh rates on your tv.
I get a bit of trouble so set my TV at 60hz while my monitor is always at 75hz.
Otherwise the screen goes slanty and stuff.

Use dual-view and just drag the VLC over to the tv screen and you should see it on both screens then when its on tv, fullscreen it.

If your laptop has an nvidia card in it, you are fine and can use dual-view.
Since its a laptop i'm not sure, if might be on-board, and then i dont really have a clue where the settings will be.

John, you are an absolute genius!! I appreciate your help! Video files are work when I use the screen switch.

I am using S Video to S Video, I do have a VGA socket, is this a better quality than S Video? And does it show Picture and sound? As I have one wire for picture, and one for sound atm.

Thanks again, much appreciated!

Haggis, my LCD screen does seem to flicker a tiny bit, kind of like the old CRT monitors did, anyway to fix this?

VGA is far better quality than s-video - the latter is a low resolution interlaced signal whereas a VGA signal can match your screen resolution and type far better. LCD TVs are not good at displaying a resolution other than their maximum one which means you lose quality for the TV to try and match the input resolution whereas a VGA cable can work at the same resolution as the TV. It's video only, you'd still need a separate cable for audio.

Which TV and laptop is it you have, it would help to know that just to make sure you're being pointed in the right direction.

I have a Samsung X20. So the best thing is VGA to VGA?

The Video quality is ace, and I can read what Im wrting, also the sharpness can be better! But nothing major!

Looks like you should be good to go VGA to VGA as long as your TV definitely has this port.

O one more thing mate, I have a 1cm gap at the top and bottom, and a 1/2cm gap at the sides, is there a way of making it full screen? The options on my LCD don't do it
