Dell poweredge 6600 no display

To connect three monitors to a Dell Optiplex 7010, you can use the built-in DisplayPort (DP) ports and the VGA port. Here's how you can set it up:

1. Check the available video ports: As you mentioned, the Dell Optiplex 7010 has two DisplayPort (DP) ports and one VGA port. Make sure all three monitors support at least one of these connection types.
2. Connect the first monitor: Use a DisplayPort cable to connect the first monitor to one of the DP ports on the Optiplex 7010. Ensure that both ends of the cable are securely plugged in.
3. Connect the second monitor: Connect the second monitor to the other DisplayPort (DP) port on the Optiplex 7010, using another DisplayPort cable.
4. Connect the third monitor: Since the Optiplex 7010 has only two DP ports, you'll need to use the VGA port for the third monitor. Connect the third monitor to the VGA port using a VGA cable.
5. Configure display settings: Once all three monitors are connected, you'll need to configure the display settings to extend the desktop across all monitors. Right-click on the desktop and select "Display settings" (Windows) or "System Preferences" -> "Displays" (macOS). From there, you should be able to set the arrangement and orientation of the displays.

Note: When using multiple monitors, it's important to consider the graphics capabilities of your computer. The Optiplex 7010 might have limitations on the maximum resolution and refresh rate it can support across multiple displays. Check the specifications of your specific Optiplex 7010 model to ensure it can handle three monitors simultaneously.
If you encounter any issues or limitations, you may need to consider using additional hardware, such as a DisplayPort splitter or an external graphics card, to connect and support three monitors.

If you have multiple video connections (onboard from motherboard, usually vertical or stand alone video card, usually horizontal) that you plug into the stand alone card, as the onboard is normally disabled when the expansion is installed. Verify the cable and monitor both work and that the monitor is on the correct input. Finally try another video card, if you have one available. Even if the drivers are not correct, etc, you should still see a boot screen.

To get monitor work for you, you should connect the VGA cable to CPU. When you remove the VGA cable, monitor has got nothing to display so it goes in stand by mode with orange LED on.

Dell Inspiron 1420 Notebook PC?

The white screen can be fixed. How?

Connect a VGA monitor to the laptop. Connect to the VGA port on the right rear. Example of a VGA Cable, and VGA connector,

http://en.wikipedia.org/wiki/VGA_connector

You can use a CRT type monitor, (Looks like a small TV), or a flat LCD screen monitor that has a VGA cable.
By default the display should show on the external VGA monitor.

No?
Press, and hold the Fn key down, and at the same time tap the F8 key ONCE.
Still no?
There are at least 3 display options available;

1) Internal monitor of laptop ONLY
2) Internal monitor of laptop AND external VGA monitor
3) External VGA monitor ONLY

Hold the Fn key down again, and tap once more on the F8 key.

No display on the external VGA monitor, means you have a bad graphics chipset. Replace motherboard.
Display does show on the external VGA monitor, means you have a problem with;

1) Video Cable
or
2) Screen Inverter
or
3) LCD screen

Video Cable:
The Display Panel Cable (Video Cable for Dell), connects to the motherboard by the left Hinge.
Goes under the left Hinge, and up into the Display Assembly.
It then connects to the Screen Inverter, and to the back of the Display Panel. (LCD screen for Dell)

From normal opening, and closing of the laptop, the Display Panel Cable may become pinched in the left Hinge.
This can cause;
A) The connection at the motherboard to come loose
B) The connection at the back of the Display Panel to come loose
C) Stretch the wires inside the Display Panel Cable's sheath, and damage the wires. (Break)

If you are lucky just the connection at the motherboard, and/or connection at the back of the Display panel, may have come loose.

Diagnoses is to NOT just look at the connections, but physically push the connectors of the Display Panel Cable, into the connector at the motherboard, AND back of the Display Panel.

Visually inspect the Display Panel Cable's sheath. Do you see any outward appearance of damage? This means the tiny wires inside may be damaged.
Replace the Display Panel Cable.

Remove ALL power. Remove the AC adapter (Charger), and Battery.
Remove the Keyboard Cover.

Unfasten the Keyboard, LEAVING the Keyboard Cable ATTACHED to the motherboard. Roll the Keyboard over, and lay it upside down on the Palm Rest Cover,

[ NOTE*
Two Philips head screws at top of Keyboard. After removing, lift the top of the Keyboard up a little, slide it a LITTLE towards the Display Panel.
DO NOT lift it straight up at first.
There are 3 plastic tabs on the bottom of the Keyboard, that slide into the Palm Rest Cover. If you pick it straight up you will break those tabs off ]

In Removing the Display Assembly, note where number 1 points to.
This is the Display Panel Cable's connection, TO the motherboard.

Note where number 2 points to. Those cables going to the Mini-Card Antenna, HAVE to be reconnected, right back to the SAME terminals on the Mini-Card. Make a mark on the cables, and matching marks on the Mini-Card.

Use the instructions in Removing the Display Bezel.
Use the instructions in Removing the Display Panel.

View the last illustration in Removing the Display Panel.
Note how the Display Panel Cable attaches to the Display Panel, and Screen Inverter

Number 2 points to the connection at the back of the Display Panel
Number 6 points to the connection to the Screen Inverter
The Black connector that is not numbered at the bottom, is the motherboard connector of the Display Panel Cable.

This is a better view of the screen Inverter,

http://www.ebay.com/itm/Dell-Inspiron-1420-1421-LCD-Inverter-Backlight-Combo-/370274752470

Display Panel Cable checks out? Look at the screen Inverter. This small circuit board is located at the bottom of the Display Panel, and behind the Display Bezel. Closer look at link listed above.

Is the cable coming from the Display Panel Cable, plugged in tightly to it?
Does the screen Inverter look damaged?

Beeping usually means that you have a defective memory stick which is shorting out your power supply.

If the display works fine when connected to external screen via VGA connector then then the problem is either with the LCD display panel ( which consists of the display panel and inverter ) or the LCD cable that connects the LCD to the motherboard. You could try to re-seat the cable connection on the back of the LCD panel.

check your cable PC to monitor or try to added vga graphics card

1-3-2 is "No memory installed."

Table 3-8 is the beep codes.

The battery is probably a CR2032, That is the standard these days.

If you are not getting display for your Dell Optiplex GX 270, the issue may be one of three possible causes:

* The VGA cable connection between the Dell PC and the monitor, may not be seated in the VGA port correctly. To resolve this, just make sure the VGA cable is seated completely in the VGA port of the Dell computer and that also the Power cord from the monitor to the power source (i.e wall socket, power strip, surge protector, etc.) is seated securely.

* There may be an issue with the Video card in the Dell PC

* Or there may be an issue with the motherboard for this model of Dell.

To check to determine if the latter is what you are experiencing with this issue, please feel free to review this Dell Support link: Dell Optiplex GX 270 Display issue.
