I just purchased this PC for a user

Lenovo ThinkCentre E73 Desktop PC - Intel Core i3-4130 3.40GHz, 4GB Memory, 500GB HDD, DVDRW, Windows 7/8 Pro 64-bit

The PC has Win 7 64 bit loaded

This users has 3 monitors
 monitor 1 uses serial port
monitor 2 uses a USB connection
(BOTH of the above monitors are working with the new PC)

I trying to hook up a 3rd monitor and this did work on a former PC

The PC has a DisplayPort and the Monitor has a HDMI port

on his past PC I connected the HDMI to DisplayPort cable and it worked

on this PC nothing happens.

I cannot find the displayPort in the Device Manager of the PC

What am I doing wrong?

I believe that the graphics card on the Lenovo ThinkCentre E73 has AMD Eyefinity technology, in which case the answer is to get an active adapter, not passive. For example, I have a computer with AMD Eyefinity technology, but I could get only two monitors working initially. The solution was to get an active adapter. I first purchased this DisplayPort (male) to DVI (female) Active Adapter for one office:
http://www.amazon.com/gp/product/B004SUO1GM/

It works perfectly. I now have three monitors working where before only two of the three worked at a time. For a second office where I was having the same issue, I purchased this DisplayPort (male) to HDMI (female) Active Adapter:
http://www.amazon.com/gp/product/B009YC3W1Y/

This also works perfectly and I now have three monitors working at that office, too.

The StarTech website has a good explanation of why you need an active adapter instead of passive to get the three monitors working:
http://www.startech.com/AV/Displayport-Converters/Active-DisplayPort-to-DVI-Adapter~DP2DVIS

Also, the AMD website has this nice description (and other excellent material) of the basic requirements for connecting multiple displays:
Connecting multiple monitors for AMD Eyefinity technology couldn’t be simpler. There are four easy rules to remember:

1. The first two monitors can connect to the graphics card with any display output on your product: HDMI, VGA, DVI or DisplayPort.

2. The third (or greater) display must be connected to the graphics card via DisplayPort.

3. If your monitor does not have a DisplayPort connection, you will need an inexpensive active DisplayPort adapter for it. DVI to DP adapters can be had for less than $30 USD.

4. Every family of GPUs supports a different maximum number of displays.
Of course, the computer must have AMD Eyefinity technology for this solution. Regards, Joe

Hi syarmush,
You're welcome. Happy to help. Regards, Joe

Hi Mods,
Seems that the asker accidentally picked his own post as the answer instead of mine. Since his comment was, "this is good info     Thanks", I'm sure he meant to pick my "good info" post <http:#a40518704> as the solution. Please fix when you get a chance. Thanks much, Joe
