Bright pixels

[jdr1984]

Just bought this monitor about a month ago. My background image is a Welsh flag centered on the screen with an all black border. This morning I noticed a bright green and a red dot in the lower section of the border. Should I be concerned? The DVI cable is brand new & has gold ends

@jdr1984 Greetings from the HP Community!

Here's what you need to do, to identify the issue and resolve it accordingly:

• If not done already, check with an alternate monitor, if you don't have one, check if it works fine on the BIOS screen to identify if it's either a hardware or a software issue:
  • If it works fine on the BIOS (Accessed while tapping F10 during a restart) it's a software issue & I suggest creating a new user account to check if that works better, for starters)
  • However, if it doesn't work within the BIOS either, I'm afraid it's a hardware malfunction.

While you respond to that, I have a few more steps that should help: 

Perform a power reset (no data loss) using these steps: Click here, proceed to next step if this works

Attempt to run a test from the HP hardware diagnostic tool, using this link: Click here for details.

If the issue appears on the diagnostics, it could again, determine a hardware failure,

If they don't appear on bios & the hardware tests passed: please update the BIOS & Chip-set drivers from the HP website using this link: Click here
