[Ace345]

Hi I'm new to this my son wanted dual monitors he has an rx570 4gb card with 1 hdmi and on-board with 1 hdmi he's got a monitor on each but one goes blurry he has 3 dp connections on the gpu can they be used instead of hdmi ports

Most modern computers can do dual display.

However,  if one monitor is looking bad it would likely be the monitor or the cable.

I have a older Dell desktop with Winnows 10 and the main screen is a TV set that allows VGA input. The other is from a GPU card that drives a HDMI cable .

There are many, many variations you could have.

If you provide some details about the computer, some expert here might be able to help. Please mention what OS you are using. Is it Windows 10?

Never tried dual display from different (!) outputs but it looks like it's working. The best option is that you get dp to hdmi adapter and connect both display to gpu only!
