Summary: Depending on what you're doing, you may or may not need digital video output for your LCD monitor.
|
I'm thinking of buying a TFT (LCD) screen. The model which I can afford only has analogue inputs, what do I lose out on if I don't have digital inputs? |
I love my LCD monitor. I highly recommend them. Not only are they clearer than their older CRT counterparts, but in general they use less power and take up less space.
But what's the difference between an analog or digital input?
•
In a nutshell, the difference is sharpness.
An analog signal will be somewhat less sharp and has the possibility of some small amount of ghosting depending on the quality of the cable and connection to your computer.
Because there's no digital to analog and back to digital conversion - a digital signal avoids all that. The images will generally be much crisper and clearer.
If you're stuck with only an analog connection, either because your computer has no digital output or because your monitor has no digital connection, you may or may not notice. It depends on what you're doing, the quality of your video card, cable, and specific monitor.
Either way, it'll still be much better than a regular glass monitor.

I was wondering how I could find out if my computer and monitor where DVI compatable as I wanted to upgrade my computer by buying a GeForce 6800 GS to replace my old rubbish GeForce 4MX 440-SE.
Thanks...if this article even makes sense!

Posted by: J-Spartan at September 9, 2006 3:24 PMI have a computer, an LCD monitor and Direct TV satellite. I want to either use my current monitor to somehow watch TV via the satellite, ot I want to buy a new LCD that willserver both purposes. What is the best way to go about this without having a whole nother LCD sucking down power?
Posted by: Frantz at November 19, 2006 8:37 PMMost newer PC video cards have:
- a standard 15-pin sub-D VGA connector which outputs an analog signal
- a DVI-D connector which outputs a digital signal
If your LCD TV has a VGA connector, then you're all set to go. If it has an HDMI connector, you can buy a DVI-D Male to HDMI Male cable and use it connect your video card to your LCD TV. You'll have to tinker with the video card display properties in Windows in order to set the output resolution to one that is as close as possible to the native resolution supported by your LCD TV.
Conversely, you can also hookup an HDMI source (such as digital set top boxes & DVD players) to a PC LCD monitor using the same cable mentioned above, provided the monitor has a DVI-D connector which accepts digital signals. Since DVI does not carry the audio signals from the HDMI source, you'll have to connect your speakers directly to the audio output of your HDMI source to get sound.
There are other solutions for converting composite/S-video/component signals to standard VGA - many video game retailers have converters that will do the trick.

Posted by: Peter Vo at August 8, 2007 4:39 AMI have a Dell desktop computer (Dememssion E510) and I like to use a monitor to hook up with my DVD player only. What is a accesory can i buy to use with? or I want to buy a LVD TV then I can use them both for regular TV and computer. I do not want to have 2 of them in my studio room (TV and Monitor)Thank you very much
Hi.
I have a graphics card with both one analog and one digital outputs.
I also have two analog TFT monitors ahd have attached both to the same graphics card, with a simple DDI to D-Sub converter on the Graphics card digital output.
I have also configured the OS (WIN XP) to allow the two monitors to act as one large extended workspace.
Now the problem.
Every now and again I get a problem where one of the screens will become distorted. Then it fixes itself after some minutes / hours.
I swapped the connections around and the other monitor then showed signs of the problem.
Any ideas please? Do I need a more clever DVI to D-Sub converter?
Regards, Dave
Posted by: Dave Green at October 16, 2007 6:57 AMI have a HP a1129n which I bought a approx. 3 years ago. I just bought a samsung 2333. The HP only has an anslog output not a digital. How can I convert it to digital. Looks like I have 3 more horizontal slots on the back of the CPU that are not used. Do I have to add a digital output, or is there another way?
