Connecting HP 6349 to Samsung 2494SW monitor

Hewlett-packard Pavilion p6340f desktop...
July 20, 2010 at 21:58:24
Specs: Windows 7
I try to connect it using the DVI cord and I get no digital signal. The monitor acknowledges that it is connected via DVI but is not receiving a digital picture. I connect using VGA and it works fine (but the picture is not high resolution) HP chat told me that I needed an external graphics card in order to get digital signal through DVI to the monitor, is this true? If so please explain why and please recommend an inexpensive graphics card.

"but the picture is not high resolution"
the correct resolution is 1920 x 1080 1080p. Make sure display driver is installed, if u can't find 1920 x 1080 may be the igp isn't support the high resolution.
The psu is weak (300w) look for video card that use low power. I recommend nvidia gt 240 gddr5, ATi radeon hd 4670/4650/5450.

- he made two Topics about the same subject but for two different Pavilion models.


Your Samsung 2494SW monitor model supports a DVI input only. It came with a DVI cable. Use only the DVI cable it came with.

There is no such thing as an adapter or cable that you can connect to a VGA port to get DVI video output - there are not enough connections to a VGA port for that to work.

"HP chat told me that I needed an external graphics card in order to get digital signal through DVI to the monitor, is this true?"

It is, ONLY if you want to connect to a monitor that requires VGA input via the DVI port.

Both the Pavilion computers you specify in your two posts have onboard video that has a VGA port and a DVI-D port.
A DVI-D port has digital output only . A standard DVI to VGA gender adapter will not produce VGA video when plugged into a DVI-D port. As far as I've seen, only some onboard video has a DVI-D port - DVI ports on video cards (that you install in a slot - onboard video - video built into the mboard - IS NOT A CARD) are DVI-I - those ports DO support using a standard DVI to VGA gender adapter with a monitor that requires VGA (analog) input.

If the present display settings in Windows on either Pavilion computer are not supported by the monitor model, you will get no video on the monitor.
To fix that, see this

If that doesn't help, your 2494SW monitor is probably defective, or has been damaged by you doing something you shouldn't have.
Try it with another computer.

Thanks for the detailed replies guys! I tried to delete this thread because I mistyped the computer model number, the correct model number is 6340f.
Tubesandwires- The 2494SW has both VGA and DVI inputs, VGA is what I am using right now since I can't get it to work with the DVI. I can't even get the computer display settings to go to 1920 x 1080, only will go up to 1280 x 1024 which is the limit on the scale given.

You can't delete a Topic you started, or any posts you have made, on this site - only the forum moderator(s) can do that - but you can usually Edit your own posts, or change what is in your posts, or delete what was in your own posts (a post can't have no content at all).

You should have made your corrections in a second post under the same Topic, or....

You can Edit your own posts on this web site by clicking on the notepad icon at the right end of the icons at the top of your post, except possibly the first one, if you started the Topic, after at least one Response has been posted.

I did not see anything in the 2494SW info I looked at that indicated it has anything but a DVI input, but I might have missed that it has a VGA input too.

Usually when a monitor has both VGA and DVI input ports, you cannot connect both at the same time - only one or another will work. If the VGA video cable can be unplugged at the monitor, that may or may not apply to connecting the monitor video cable even when both are not connected to the computer video ports - unplug the VGA cable at the monitor if that applies when connecting to the DVI port .

The resolutions you can choose in Windows depend on which monitor drivers have been loaded, and which video drivers have been loaded for the video adapter in Windows.
By default, Windows usually loads Plug and Play Monitor drivers, or the equivalent they're called in Vista or Windows 7, unless the specific video drivers for the video adapter have not been loaded in the operating system, in which case it may load a Default Monitor driver which yields you relatively low resolution video and very limited resolution choices.

The specific video drivers for the video adapter have already been loaded when you still have the original HP software installation you had when you got the computer, but if you have re-loaded Windows, those are probably NOT built into Windows , and you must load the proper video drivers, e.g. by installing the video drivers download found in the software downloads for your model on the HP site .

In any case, you should be able to get at least crude low resolution video when you connect the monitor via it's DVI input to the DVI-D port output, when you do the procedure to load low resolution video I pointed to at the end of Response 2.

The same link I pointed to has other info that tells you how to load the specific monitor drivers for your Samsung model, but the video drivers for your specific video adapter must have been loaded in Windows as well.

When you load the specific monitor drivers for your monitor model and the specific video drivers for your video adapter have been loaded, by default Windows only shows you the only the resolutions that both the monitor model and the video drivers support.
As far as I've seen, computer models with a mboard that has an onboard DVD-D port are recent or fairly recent, and you should be able to choose a resolution higher than you're quoting in that situation.

If you can't choose 1920 x 1080, you can choose another resolution that has the same ratio of width to height to get a properly proportioned display, but the display will not look as good as it does when set to 1920 x 1080 - the most noticeable thing being text will not be as clear.
Turn on Clear Type in Windows XP or Vista - makes type/fonts on LCD screens look clearer.

1920 x 1080 is a 16:9 (16 to 9; 16 x 9) display ratio.
When you divide 1920 by 1080 or 16 by 9 you get 1.7777etc.
Any other resolution that yields you 1.7777 or close to that when you divide the first number in the resolution by the second number will yield you the proper display proportions that suit your monitor.
