Be careful with the HP Computers. I have one and purchased an nVidia card that gives me three monitors. Unfortunately, many of the PC computers do not have a power supply that will accommodate this. The graphics cards that take up two slots require extra connectors from the power supply that the HP proprietary power supplies do not have. In addition, you cannot upgrade the power supplies in these HP desktops because they do not use a STD ATX power supply. Make sure that the video card you get is a one slot card and does not have two six pin auxiliary power connectors. If it has one, you are OK. I have to put an external power supply on the outside of mine and run the power to the card. I then had to connect the green and black wire on the 24 pin connector together to make the power supply think it is on. really a pain in the neck.

SOURCE: is this computer pci express x16 video card compatible?

Hi,

To my knowledge it does not have PCI Express but standard PCI only. For an add-on video card, it has an 8X AGP slot.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

SOURCE: What video card are compatable with SR1620NX ?

A PCI Express graphics card.

Doesn't matter if the PCI Express graphics card uses the PCI Express 2.0 technology, or the PCI Express 2.1 technology.

The PCI Express graphics card, will insert into the PCI Express x16 expansion slot on the motherboard.


Supporting data;

1) View of the motherboard in an illustration,

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00378480&tmp_task=prodinfoCategory&lc=en&dlc=en&cc=us&lang=en&product=1127351

Scroll down the page to view the motherboard illustration.

A) Looking at the illustration, view the BATT. (CMOS Battery)

To the left of the CMOS Battery (BATT) are three white PCI slots.
Above them is a longer expansion slot. This is the PCI Express x16 slot.

Above it is marked > PCIX16X1 (PCI x16 times 1 slot)


NOTE* When installing the PCI Express graphics card, lift up gently on the Lock 'handle'.
It looks as though you should push down on it, but you need to lift up on it instead.


Also go above the motherboard illustration, and read to the right of the heading > Internal Connectors

In the list you will see > One PCI Express x16 graphics slot.


WHEN installing a graphics card, ALWAYS install the software from the CD disk provided, First!

Computer on, and Windows running, insert the graphics card's Installation disk, (CD) into the optical drive tray.
Install the software by following the directions.

THEN shut the computer down normally, and unplug the computer from power.
OBSERVE Anti-Static Precautions.
Install the graphics card.
Close the computer case, and plug the monitor into the graphics card.

Turn the computer on.

When you install a device (Such as a graphics card for example), Windows will try to find compatible drivers.
IF, THE driver is not installed First, Windows will match up one of it's thousands of generic drivers.

This = No.

You want THE driver installed first, so that Windows will find it, and Not try to match on of it's generic drivers.

NOTE 2*
It DOESN'T MATTER what graphics ram memory the graphics card has.
The graphics card's Processor and Ram Memory operates independent of the system resources.

Example:
The computer uses DDR Sdram ram memory.
The graphics card uses GDDR5 graphics ram memory.

It will work just fine.

NOTE 3*
It does NOT matter if your computer uses the PCI Express 1.1 technology, and the graphics card uses the PCI Express 2.0, or 2.1 technology.

PCI Express 2.0, and 2.1 technology is Backward Compatible with PCI Express 1.1 technology.

Will you get the full capability of the PCI Express 2.0, or 2.1 graphics card?
NO

Will you notice?
NO


What you need to look at it, is how much power will the graphics card use. Look at the system requirements for the graphics card, and be sure your Power Supply has enough power for that graphics card.

Also, IF, the graphics card requires additional power cables from the Power Supply, make sure your Power Supply has the required power cable, or power cables.
IF the Power Supply does not, use a power adapter cable.


NOTE 4*
Graphics card manufacturer's base the power needed for the graphics card, Not just on the graphics card itself, but on an entire computer system, AND the graphics card.

The graphics card manufacturers use a test computer system, that is a powerful computer system.
Gamer motherboard, Dual Core, or Quad Core processor, 4GB of ram memory, and at least two harddrives, and two optical drives, PLUS the graphics card in question.

This complete computer system uses a LOT more power than just the graphics card by itself.

There isn't a single graphics card out there, that uses more than 150 Watts by itself.

Recommendations for a graphics card that is compatible, with a Compaq Presario SR1620nx desktop computer?

Budget to medium:
Good enough to watch videos, older games, and some newer games.

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=4675217&CatId=3670

Medium:
Higher level games, and large screen monitors,

SOURCE: Need a video card that will allow us to hook up a

The short answer is no. The belief that widescreen HD monitors require special video cards derives from a combination of two sources. First, most Windows users know that you can change the display resolution by right clicking on the desktop, clicking on settings, and then choosing a resolution from a drop-down menu. What most users do not know is that the choices displayed in that drop down menu are what Windows, the Video Card manufacturer, and the Monitor's manufacturer want you to see. The fact is, most video cards are capable of displaying popular widescreen resolutions such as 1680x1050 dpi and 1920x1080 HD which are 16:10 and 16:9 resolutions.

Which part of the video-cards are "too large" -- the electronic circuitry, or just the "spine"?

If just the "spine" is too tall, then unscrew the spine from the card, and attach a shorter spine.
Or, if you are "brave", then run "*****" -- don't attach any "spine" to the video-card.
Just connect the VGA/DVI cable from the monitor directly to the video-card.

Desk top dell has a black screen


If your dealing with a black screen on a dell desktop it could mean a couple things. First make sure your monitor is connected to the back of the computer. Second make sure its connected to the right video card because there may be 2 of them. The one at the top is the on board video and a lot of people add a better one in a pci slot towards the bottom. In event that is not the case and the monitor is turned on it could be a faulty video card, bad driver, or the video card needs reseated.
1. turn off computer Sometimes when moving desktops pci cards are jarred and need reseated.
2. Open the case at the back by removing the two screws holding on the side panel
3. then remove the screw that is holding the pci video card, pull out the card
4.then reseat
5.rescrew
6. restart
if this doesn't fix the issue then buy a video card that is compatibly to your motherboard and replace it

if it is an onboard video card buy a pci or pci-e or a video card that is compatible for your computer

Connect 2nd monitor to small form factor dc5800


Hello.

You have 2 options to connect an additional monitor to your desktop:

1. install a low profile video card that has multiple video outputs
2. purchase a USB to VGA/DVI device to allow a 2nd monitor to be connected.

Your model PC does not have a DisplayPort on it (newer PC's have this and this provides another monitor connection). So you will need to add hardware to the PC so you can connect the 2nd monitor.

Because you have the "Small Form Factor" model, standard height video cards will not fit in it. You would need to get the shorter model video card - typically labeled "low profile".

The other option is to purchase a USB to VGA or USB to DVI adapter that would allow you to connect the second monitor to your PC. The only thing to watch for when getting this type of adapter is to make sure your current Operating System is supported by the adapter. Many adapters that work on Windows XP will not work with Windows 7 or 8.

I am looking for a monitor driver for Windows Vista for LT1919


Windows XP and Vista should "auto-detect" the capabilities of this LCD screen.

If not, access http://WindowsUpdate.Microsoft.com
and scan for updates.
When the scan is done, look for "optional hardware" updates.
If Microsoft has a driver, it will be offered for download.

Screen turns black and blue LED is blinking


Sounds like the monitor is being made to show a resolution it does not support. Check the available resolutions the monitor supports and then check what resolution the video card is giving, if it not compatable, you get the black and blue screens.

For the video card, right click on the desktop in a an empty area and choose properties > settings > your resolution from the card will be there. Now from there click on advanced > click on monitor and look at the monitor settings. Make sure the box is checked to hide modes the monitor cannot display. Now click on the adapter tab and click below on all modes. This is the list of all modes that both the monitor and the video card argree on. Make sure the settings in your game match one of these and you should be good to go.

3 monitors on dell vostro 200


Go to your bios and check if your bios allow that. Usually if you connect a card on the motherboard slot automatically the on board card becomes unavailable.
If your bios doesn't allow to make changes you can add another pci video card or connect some vga split signal to get the image on 3, 4, or more monitors with a single device.

Flashing Green Light on mx705 monitor


If the HP has onboard video but you have an add-on video card, remove the add-on and connect the monitor to the onboard vid. If it works you have a bad add-on video card. If it doesn't or you are already running on on-board video hook the mx705 up to a compatible HP. The older PB may be TOO old to handle it or not hve the correct drivers.

Intel onboard graphics card does not recognize two monitors connected through Matrox Dualhead2Go


You may have to upgrade to a new video card to get it to work properly. Onboard graphics are often crude with not much for options. Even a cheap video card should be good. Here are a couple of links to check compatibility:
http://www.matrox.com/graphics/en/corpo/support/compatibility/compatibility.php
http://www.matrox.com/graphics/en/gxm/support/tool/home.php
Other solution is to re-install software for the Matrox.
