Ok here's my predicament. I bought the Razer Blade 2016 for college, however was planning on gaming with it. I want to play on a 144hz monitor for Counter strike however I don't know if I can play 144hz with an HDMI 1.4b (I've heard that it can support 120hz however in 3D). I know the laptop has a thunderbolt 3.0, can I use this somehow with an adapter to shell our 144hz?

Razer Blade 2016:

Intel i7-6700HQ 3.5ghz
Nvidia DTX 970M 6gb GDDR5 VRAM
16 GB DDR4 RAM
512GB m.2 PCIe SSD

Thunderbolt 3(USB TYPE-C)
HDMI 1.4b
Battery 70 Wh

In that case just use displayport, or at worst displayport to dual-link DVI. 100% of 144Hz monitors should support at least one. If you have an option, go with DP

Ignore thunderbolt unless they specifically say displayport capable in which case you can definitely use that.

As for HDMI, theoretically you should be able to, but you need support for it on both the computer and monitor. Check if the monitor claims 144Hz over HDMI (read the manuals), if not, might not work.

Being at home this box that houses a full sized gpu might be an idea? http://kotaku.com/razer-blade-2016-review-it-keeps-getting-better-every-1780881943


Just a random silly thought, was trying to see if Club3D's HDMI2 to DisplayPort can work in reverse but can't find anything atm. Don't think it could but wondering if this Laptop has HDMI2 being a 970m that connecting the HDMI2 to a DisplayPort monitor would work and allow for custom high refresh rates.

Your motherboard/graphics MUST support that mode of operation to work (see my post above). Read the manual carefully.

There are active USB2/3 to DVI/VGA/displayport adapters too, but those will NOT work with 144Hz or games in general

HDMI 1.4b only does 120hz in 3D. While the bandwidth is there, the clock rate isn't. The way they get 120hz through 3D, is by sending both the right and left eye in a single transmission, then split them up, and send one eye at a time in sequence. They call it frame packing. For normal 2D displaying, it doesn't work. Although I imagine some hack could be used to force frame packing in 2D, only it would result in higher latency.

HDMI 2.0 supports 120hz.

There may be some DP to HDMI 2.0 converters as well, but the display has to support HDMI 2.0.

The next problem is most laptops simply don't support 120hz. I'm not sure the cause, but I'm told it's just they use lower end ports.
