SER5 Max - random pixels on display

6502dude

I bought a SER5 Max for a xmas present for a friend and started to set it up last night.

Display has random pixles on display that change on screen refresh when on static photo / image or Windows background.
The random pixles also occur during video play either from YouTube or MKV / MP4 files.

I have:
> replaced HDMI cables - no change for random pixel problem

> tried DisplayPort cable - no change for random pixel problem
> tried different HDMI displays - no change for random pixel problem

> updated video drivers  - no change for random pixel problem
> rebooted may times  - no change for random pixel problem
> tested without USB keyboard / mouse attached  - no change for random pixel problem

Problem occured before any 3rd party software (non Windows11 software) was installed.

I am looking for a solution to this issue.

Is hardware defective and need to be returned?
Thanks!

I guess since no help, I will return this device.
It is my 1st time trying this manufacturer for a product and it has been a disappointment.

Hello there,
First,you can try to clear the CMOS,Please unplug the power supply and HDMI cable. Please try to hit the hole of "CLR CMOS" with a needle or a pin for about 10 seconds.Ten minutes later, plug the power supply and HDMI cable, then turn on the PC after 10 minutes
Second,you can try to uninstall the graphic card and install it.
Hope it can help you!
