HP spectre x360 screen becomes white and unresponsive

[DanSJ]

My spectre's screen recently cracked and I replaced the entire display 2 days ago. My old screens resolution was 1920x1080 and the new screen, while looking exactly the same and having the same connections to install, is a 2560x1440 resolution. It installed easily and seemed to be working fine for the first 20 minutes or so but it suddenly froze up while the screen progressively started fading to white. I've tried to do a system recovery and update graphics drivers and the bios but that hasn't worked. I also disabled everything in the power settings in the intel graphics settings as other people suggested in other posts but that didn't work either. It seems that shutting the laptop and reopening or just putting it into sleep mode and quickly waking it back up temporarily fixes the issue but sometimes I get flashing lights around the edge of the screen and it always becomes unresponsive again eventually, 20 minutes usually being the longest it goes without.

I've seen other people with the exact same problem but I'm just wondering if the issue is with the compatibility of the 1440p screen with my spectre, the fact that I bought a faulty display or if it's something completely different like the drivers or what not.

Welcome to HP support community.

Check if the issue occurs when connected to an alternate monitor?

Meanwhile:

Run Extensive system test to check for hardware failures.

1. Hold the power button for at least five seconds to turn off the computer.

2. Turn on the computer and immediately press Esc repeatedly, about once every second. When the menu appears, press the F2 key.

3. On the HP PC Hardware Diagnostics (UEFI) main menu, click System Tests.

4. Click Extensive Test.

5. Click Run once, or Loop until error. While the test is running, the time remaining and test result for each component are shown on the screen.

Let me know how it goes.
