It sounds like you have not loaded the HP chipset drivers;

 

https://support.hp.com/gb-en/drivers/selfservice/hp-z620-workstation/5225037

 

Specifically, install this driver set;

 

HP Z420, Z620, Z820 Windows 7 x64 Driver Pack located in the Manageabilty-Driver Pack

 

I also recommend you download and install the HP Support Assistant software and HP Performance Advisor software.

 

After installation, check the drivers are loaded in Device Manager.

everything is loaded now...but the gpu is still doing the same thing! if i install the drivers and restart my screen goes black right before you hear the windows tune. Note that ive tried all the output ports too just in case it was a faulty display port.

funny thing (which is confusing the F**** out of me)-->my gpu has 1dvi and 2 display ports, if i convert the dp to hdmi then plug it into my monitor (LG Ultrawide) everything works fine with generic VGA drivers...but if I use dp straight to dp on my monitor it shows no signal at all not even in the begining when I update the drivers for my gpu the screen just goes black before the windows tune (if i'm using dp to hdmi) and nothing with Dp to dp

Can you tell me what GPU card you are trying to install? Also, what BIOS version do you have?

Do you have an auxillary PCI power connector plugged into the Quadro 4000 card? This card is 142W and therefore requires additional power via a 6-pin PCI power connector.

 

The only other issue I would be looking at is tha maximum resolution supported by the Quadro 4000 since you are connecting a LG Ultra-wide display. I am assuming this has a native resolution of 3440 x 1440 pixels similar to my Samsung 34" curved Ultra-wide display (21:9 aspect ratio)?

(untill the image updates; Maximum Display Resolution Digital @ 60Hz = 2560x1600)

 

 

Re- Windows shield;

 

Go to start button, type in UAC in the search box, and set the slider to the lowest setting to disable UAC and reboot. Caution must be exercised since you will now be running everything in administrator mode.

Another issue I have seen with installing 'older' gpu's on HP Z workstations is the PCI lane speed. This is specific to GPU cards that are not PCIe Gen 3, the Quadro 4000 being PCIe Gen 2.

 

I would recommend you limit the GPU PCIe slot speed via the setting in the BIOS, i.e. set the PCIe slot speed limit to 5 Gbps (Gen 2).

 

Just want to eliminate this as a possible issue.
