External laptop's screen turns black

[alvin_4]

Hello fellas . I have a new MSI GP62M 7RDX(256CA) gaming laptop. My problem is i connected it into 144hz monitor through a DVI DUAL LINK mini display port , which usually work but suddenly i started to hear some random sound and instead of 144hz its reset to 60hz (while im playing CSGO and other games but in DESKTOP MENU i feel the 144hz rocking) and after that sound my 2nd monitor becomes black and i have to restart the game to get it back to normal. Someone having same issue as mine ? Please help me!

I have had plenty of dead cables over the years and it sounds like that DVI DUAL LINK mini display port might be playing up.

Does it happen only after a fairly decent gaming session and is otherwise ok when using the computer normally?

I wonder if the cables are a problem?
