One of two Displayports stopped working suddenly. Here is what I have tried so far:
Swapped the connection to the monitors between the two ports and the monitor connected to one no longer displaying.
I have updated all drivers using the HP Support Assistant
Anyone else experience this or I am just out of luck and need to change the display board

@Lsampath -- is this your computer: HP EliteDesk 800 G2 Tower PC Product Specifications | HP® Customer Support
It has "integrated" graphics.
One bypass is for you to purchase and install a graphics adapter card that has 2 DisplayPort outputs.
The motherboard will automatically "disable" the (failing) integrated graphics, and will use your new card.

My Desktop is not a 800 G2 but a G1 and from what I can see the two Displayports are integrated into the Motherboard. One of which has stopped working this morning

@Lsampath -- I can see the two DisplayPorts are integrated into the motherboard. One of which has stopped working this morning.
That is bad that it stopped working, but it is good that you can add-in a PCIe graphics adapter card, with two DisplayPort sockets, as I recommended, above, and it is good that the motherboard will then "disable" those onboard ports. Connect your two displays to the DisplayPort sockets on that (inexpensive) add-in card.
Done!
Of course, if you purchased the computer within the most-recent 12 months, you have the option to contact HP Support, and open a claim against the HP Warranty. HP will repair/replace your motherboard, at HP's expense. But, it could take 2 weeks to ship it away, get it fixed, and to ship it back to you.
Find any local owner/operator computer store, who can easily install the add-in graphics adapter card, if you do not have the technical skills to do it by yourself. It should take less than 30 minutes to restore your computer to "fully-working" condition.

Will this card work on 800 G1 small form factor desktop as well. Also, since I am in USA would you be able to guide me to the right card to buy? Yes, I am quite handy with computer hardware. Just need to know the right one to buy.
Thanks in advance

@Lsampath -- there are "low-profile" graphic adapter cards, that fit into a "slim" case, and there are "full-height" graphic adapters cards that fit into a "full-size" case. Some cards come with two "spines" -- one for use in a "slim" case, and another spine for use in a "full-size" case.
See: 03-26-2022 11:43 AM for: https://www.newegg.ca/p/2VV-000H-00019?Item=9SIB25VG004813
This card has two DisplayPort outputs, and is not expensive.
There are expensive cards, namely $500 to $1500, for use by "high-end" gamers, if that is what you do.
But, if you just view YouTube, NetFlix, and process E-mail, such a "high-end" card is a waste of your money.
