Hello everyone. I would like to know what cable I could use for connecting a BenQ XL2411Z 1920×1080 144hz monitor if i have a HDMI and a mini-Displayport on my laptop? Would that be enough to keep the settings at 1080 144Hz? Many thanks.

Hi Cyb3rWatcher,
It is all about bandwidth and of course the correct cables used.
In your case here is the following;
1920 px, 1080 px, 144 Hz, 24 bit, aspect ratio 1.78, 7.17 Gbit/s.
8.31 Gbit/s, CVT-R, 10.39 Gbit/s TMDS, Pixelclock 346.429 MHz.
7.99 Gbit/s, CVT-R2, 9.99 Gbit/s TMDS, Pixelclock 333.105 MHz.
About 10Gbps is going to your monitor if you choose to run at 144Hz at 1080p
A standard HDMI High Speed 1.4 cable should be sufficient in my opinion.

Hello again Paul. The standard HDMI cable didn’t help much and I even used other cables like HDMI to DVI-D dual link, Thunderbolt to HDMI. My settings from windows and nVidia Control Panel still seems to be stuck at 1920×[email protected] With the Thunderbolt-HDMI cable I only can get a higher refresh rate if I set 1280×[email protected] or 800×[email protected] but is not what I want, and I know it’s possible but didn’t find how. With the standard HDMI High Speed 1.4 cable I get 1440×[email protected] Since I bought this BenQ XL2411Z I had only headaches. I browsed a bit on the site and I found this mini DP to DVI-Dual Link Adapter and I would much appreciate your advice not only because it’s a bit expensive but because i’m sick of trying and buying lots of cables. Could that adapter be my salvation? If it helps, my system is a custom config laptop:

Intel Core i7 4800MQ @ 2.70GHz;
Motherboard P370SM (U40);
16.0GB Dual-Channel DDR3 @ 798MHz (9-9-9-24);
2 x 4095MB NVIDIA GeForce GTX 780M SLI enabled;
ForceWare version: 347.09;
Generic PnP Monitor (Mobile) (1920×[email protected]);
BenQ XL2411Z Monitor (1920×[email protected]);
Windows 7 Professional 64-bit SP1;
1x Thunderbolt (mini DP) port, 1x HDMI and a bunch of USB 3.0

Thank you for your guidance.
