Screen tear issues on external display

[brai9dead]

Hi all,

Apologies if this should be in a different forum and mods please feel free to move.

I bought a custom built laptop around 3 months ago with the following core specs:

15.6" Glossy 4K PLS LED Widescreen (3840x2160)
Processor (CPU) Intel® Core™ i7 Quad Core Processor 6700HQ (2.6GHz, 3.5GHz Turbo)
Memory (RAM) 16GB HyperX IMPACT 2133MHz SODIMM DDR4 (2 x 8GB)
Graphics Card NVIDIA® GeForce® GTX 970M - 6.0GB DDR5 Video RAM - DirectX® 12
1st Hard Disk 1TB Samsung 850 EVO 2.5" SSD, SATA 6Gb/s (upto 540MB/sR | 520MB/sW)
M.2 SSD Drive 256GB SAMSUNG SM951 M.2, PCIe NVMe (up to 2150MB/R, 1260MB/W

I have recently bought a Samsung u28d590d 28" 4k external monitor for use with this laptop but with the screen set to 4k resolution I am getting tons of screen tear. I have tried both HDMI and now on a DisplayPort 1.2 cable and its exactly the same.

I have tried changing a few settings in the software but I don't seem to be getting anywhere. Does anyone have any ideas?

Best wishes,

Matt

I must admit, I haven't but that may well be stretching my technical knowledge.

Running Windows 10. Some things seem to run well (Xbox streaming for instance) where as other video such as Netflix, YouTube etc seem to be very much effected. To be honest, it is also visible when scrolling quickly through pages which seems a bit odd.

Didn't know whether setting the external as the primary display might help?

Thank you for the advice
