How do i get HD picture quality from my laptop to my HDTV?

Last Modified: 2012-05-05
I am trying to connect my laptop to my HDTV to be my extended or primary monitor.  But when i do this the picture on the HDTV isn't as clear as it is on my laptop monitor.  I currently use a S-Video cable i plug into the back of my Inspiron E1505.  Is there some device or special cable i need to go from my laptop to my HDTV to improve this picture quality?  I want the quality to be the same on my HDTV as it is on my laptop if not better.  Thanks!

It's the cable. An S-video cable is not able to transmit HD images. you would need an HDMI cable. I'm sure your TV has the input for it, but it depends whether your laptop has the output port for it. If not, you could upgrade the video card in your laptop to add it in.

Good luck,



Is there anything that could go through USB to output to HDMI?  Or even convert a 15-pin VGA to HDMI?

Yes, please see the link: http://www.hdtvsupply.com/vgatohdco2.html
Most HDTV's have a VGA port on the back. I would recommend using that if your TV has one.

Unfortunately, anything other than the HDMI is going to degrade the signal. If you go from HD to VGA, you cannot get it to go back up to HD level. Same for using USB. Unfortunately you have to carry the HD signal as HD all the way. Only way to do that is with a HDMI.

Here is a great article on HDMI vs DVI vs Component Video: http://forum.ecoustics.com/bbs/messages/34579/122868.html

If you have DVI out of your Laptop, that should work as well. You generally have to find an HDMI or DVI input on your HDTV that you have the same on your Laptop.

Good luck,

Good post SLafferty1983 - that article breaks it down easy.



Wow that's kind of pricey.  I was looking not to spend more than $100 on the solution.  

I already looked for a VGA port on my TV unfortunatley it didn't come w/ one :-(.
unfortunately there is not an easy solution to this, because the hd connection costs so much.. on some of the newer cards, i am sure they come with the newest software that would allow you to have hd quality, but im not sure. companies want your money and they will do anything to get you to buy something more.


Remember the picture quality can be equal to the one my laptop produces.  Dosn't have to necessarily have to be complete HD.

What output is coming from your laptop? Is it just VGA or S-video? If so, then that is really all you are going to be able to do.

An investment into a better video card for your laptop would give you the output you need for better video, and help out your laptop performance as well if you do anything graphics/video intensive.

Good luck,



Those would be great if i had a DVI port on the back on this laptop.  All i got is S-Video, 15-Pin VGA Analog, 4 USB ports a RJ11, a RJ45, mic in, speaker out, and 1394 (i have no idea what that is for)


Do they make VGA analog to RGB Component cables? I could give that try if they did?  VGA analog is better than S-Video right?
yes i am sure they have vga to RGB component cables. just search on newegg or tigerdirect for them. VGA would be better than s -video if i had to guess.  you could also probably get a s-video to rgb component hookup maybe. try for either of them!
Hey NecroMan, since nobody asked, where are you getting all these High Definition images that you want to display on your HD TV. Do you have a Blu-Ray or something running from your PC?
The reality is that the computer world and the Internet is displayed in a resolution way, way lower than even Standard Definition TV. And the reason your HD TV doesn't look as good (and never will) is because it has to stretch the amount of resolution that it has to deal with -- and most times that's not much. The reason your little LCD laptop monitor looks better is because it doesn't have to stretch the pixels as much.  You can't improve this. Thre's a couple of sayings in the industry.
