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.

Native resolution for that monitor is 1440 x 900 (maximum) so you need to set resolution in your computer not in monitor.

OK first MSSWIN1 there are a lot of missing info in your question. Does your tv has a vga conection if it does this is easy just conect the vga cable to the the computer and the tv and the computer will dectect the tv authomatically if you're running on windows if you wantto use the computer's screen (that is if its a laptop) and the tv at the sametime you will have to go in to the settings and change it. { control Pannel=Appearenceand Personalization=Display=connect to an external display. .. Somepc's will alow you tochose fromprimary to secodary monitor,
OK if your pc does not have any VGA connector you will need a VGA to RCA convertor dont buy the cable (VGA to RCA) those don't work you will still need to buy a conversion box

Connect it to an external monitor with a VGA connection. If the external monitor comes on, yes your screen is broke.

I don't think it is a problem with the monitor or its driver.Please adjust the monitor settings on Windows by Right click-Properties-settings-Screen Resolution-1440*900.Now check whether you are getting the native resolution.

Try updating video drivers to be sure, but once you go over 3 meters, the video signal can degrade, causing a loss in the PnP signal to your monitor. Try setting the resolution manually.

The VGA connection should be fine; I have DVI and when I switched from analog, the difference was pretty minimal, to my eyes.

Is it just the fonts that are blurry, or everything? If fonts only, then this almost certainly suggests that running the ClearType tuner again would solve the problem. But this applies to all displays, so if one is good and the other is not, then this isn't it.

If everything is a little blurry, then this suggests one of two problems -- the first, you report trying, which is that the display adapter is set to a different resolution than the native resolution of the LCD monitor itself. Your display adapter should probably be able to drive 2 monitors (the built-in laptop monitor and the external monitor) at once. You should be able to set their resolutions separately.

Assuming Windows XP: Start > Control Panel > Display > Settings > at which point, you should see two monitors listed in a dropdown. Set them to their native resolutions there (using the slider bar, usually all the way to the right), and save.

If you do have the display resolutions set to their native resolutions for both monitors, then it's possible that your external monitor is messed up. A quick test would be to run the on-screen settings, usually from a button on the monitor itself. If what is displayed there is sharp and what is displayed from Windows is not, then this points to a problem with the display driver. If everything, even the on-screen display is blurry, then perhaps the monitor settings are messed up -- usually there's an option to restore to factory settings -- try that.

If that doesn't work, I'm probably out of ideas, unless you have further information.

**Your Laptop has VGA port for connecting external monitors :

Laptop Video Specs :

Laptop's Max Resolution1024 x 768
Integrated Video card : SiS Mirage M661MX

NOTE : If LCDTV does not have a VGA port, you will not be able to use it a external monitor.



Steps :
1. Connect Laptop to LCDTV using a VGA Cable
2. Right-click on your desktop and select "Properties." (or click on start > Control Panel > Display)
3. A new window displaying several tabs will appear. Select the tab called "Settings."
4. You will see boxes with numbers on the middle, in your case 1 and 2 will be present.




5. Click on 2 and click on box beside "Extend my windows Desktop onto this monitor" then choose the resolution that you like (1440 by 900) then click on apply. If 1440 by 900 is not available, choose the closest under 1440 by 900. Don't go over 1440 by 900 since that is the max value that will work on you LCD TV.

6. After clicking on Apply, the display should be present on the LCD TV. (The disply is an extended desktop so you will not see the start button nor the taskbar on the LCD TV. but it should have the same wallpaper. You can Drag the windows to the LCDTV. This will serve as an extension of you desktop. (Ex : You can watch movie on the LCDTV and you can do documents on the laptop's screen at the same time).

I know this sounds obvious but- I had the same problem, and turns out the cord want plugged in quite properly at the back of the monitor. This may not fix every problem, but, I suggest you check the cord pligged in at the back of the monitor is firmly in there and restart, then if you still get the problem, contact the company.
