HP OMEN 25 INCH monitor turns black for 1-2 seconds the more HZ the more often

[svetlinkoldamov]

My omen monitor turns black for 1 or 2 secs periodically. at 60hz it does that rarely (every couple of minutes) at 120 hz it does that around every 30 secs and at 144hz it does that multiple times every 10 secs and has black horizontal lines on the screen wherever it has white to display. I have already changed the power adapter with no success.

Hi @svetlinkoldamov,

Welcome to the HP Support Community! 

Thanks for posting your query! We're here to help you get back up and running.

If the screen turns blank for a brief period, make sure the display settings in Windows match the native resolution and refresh rate for the display.

Find the native resolution of a flat panel display on the box, in the specifications, or in the printed material that came with the display.

Some common native resolutions are 800 x 600, 1024 x 768, 1920 x 1200, and 1680 x 1050.

The most common refresh rate is 60 Hz.

This normally cannot be changed for flat panel displays using Plug and Play settings.

However, if you are using special video software to increase or decrease the refresh rate, change the refresh rate to match the default refresh rate specification of the display.

To change the screen resolution and refresh rate settings in Windows, do the following:

Right-click the desktop and click Display settings.

Under Customize your display, at the bottom, click Advanced display settings.

Under Related settings, click Display adapter properties.

Select the Monitor tab.

Under Screen refresh rate, select another refresh rate if available.

Click OK to save the changes.

If you have an HP computer, update your video drivers from the HP website.https://support.hp.com/in-en/drivers

After updating the video drivers, go back to Step 1 and try to change the screen resolution again.

Check the video cable connections. Unplug the cable and inspect the cable for damage. If the cable is damaged, replace it with a new cable. Try to use cables less than 3 meters (10 feet).

Check the environment around the display. 
Displays are sensitive to magnetic fields. Speakers, florescent lights, fans, cell phones, radios, and any other electrical device can cause blank screen or flickering. 
Temporarily move electrical items away from the display to see if they is producing a field that causes the blank screen or flicker.

Problem was indeed the HDMI cable i was using. It couldnt support the higher refresh rate. I got a new display port cable for 10 euro and it runs smooth.
