Re: Graphics card with DVI output to run business apps on 24" monitor, preferably without a fan

I will be building a quiet system and would like to have a quiet video card to run just business apps (no gaming, no CAD). I have seen that many of the larger displays just have DVI output now. Before I purchase a motherboard, I would like to choose a video card to be sure I have the proper socket. Since the card should not have to do graphic gymnastics, it should be able to be a model which doesn't need its own cooling system.
Suggestions to match these requirements?
Start here. The purpose of looking through their stock, is to get some idea
what you want. And then you can shop around (like locally perhaps) for the
Using the Advanced Search, you can set Cooler = Fanless, and type "Express"
in the search box, so you'll get any PCI Express version 1 or version 2
graphics cards. PCI Express is the slot of choice on new computers or
new motherboards. Both versions are compatible with motherboards, so you
can use either one. They both have tons of bandwidth (4GB and 8GB/sec
respectively, compared to ~2100MB/sec on AGP).
A couple examples -
POWERCOLOR AX4650 512MD2-S3 Radeon HD 4650 512MB 128-bit GDDR2 PCI Express 2.0 x16
HDCP Ready Video Card - Retail $69
And this one places the fins on the processor side of the video card.
If there is room on the motherboard (find a picture of it), then
this concept may be able to get some cooling air from the CPU fan.
If the CPU fan doesn't "spill" any air, then you could use either
HIS Hightech H465PS512P Radeon HD 4650 512MB 128-bit GDDR2 PCI Express 2.0 x16 HDCP Ready $81
According to this, the HD 4650 is 9.4W at idle. It draws 30W if you
were to play a 3D game on it.
The boxes sometimes include adapters. In this picture, the product includes
a DVI to VGA dongle (left), and a DVI to HDMI dongle (right). If you wanted
to use two VGA monitors for a wide desktop setup, then you'd need to purchase
another DVI to VGA dongle. The card can run any two of three interfaces at the
same time (dual view), and the mini-DIN connector has composite video or S-video
The 4650 appears to support "dual link" DVI. That is two digital
interfaces on the DVI connector that work to give enough pixels to
drive an Apple 30" monitor. Some older video cards have single
link connectors, so cannot go all the way to 2560x1600 with DVI
digital output. (And this is one reason I'm not searching in the
really cheap older cards, for a solution.)
"2560x1600 (dual-link DVI)"
The analog (VGA) output will drive somewhat less than that, cleanly.
So for really large numbers of pixels, DVI is the way to go. Note that
your LCD TV, while the TV may appear to be huge, when you count pixels,
it doesn't really have that many. Many of the cheaper ones are
1366 x something. There are a few expensive ones, that actually
have 1920 pixels accoss. But if you go for a desktop monitor, Apple
and Dell have some with 2560x1600. The LCDTV concept gives a very large
image, but the pixels are large as well.
