    Hey !

    So I'm planning to buy an 144 hz external monitor.
    The basic question is : can I use it ? I know that the hdmi doesn't support a signal higher than 60 hz BUT.
    If I were to use an HDMI to DVI adapter, would it display 144hz on the monitor ?

    From what I learned, you also need to have an HDMI port higher than v1.4.
    Does the razer blade have an HDMI port version higher than 1.4 ??

    Thx a lot guys !

    The Blade HDMI can output 144hz at 1080p

    But you have to make sure he HDMI on the monitor is able to handle 144hz as well.

    I am using a 1080p144hz monitor atm with a single hdmi cable no adaptors or anything.

    If you are going for 2560x1440 144hz or higher I would go for a usb-c to displayport adaptor that is capable of handling the higher bandwidth required. Thats what I did when I had an Asus MG279Q before

    what is your version of your razer blade ...???
    if you have CPU-6700 and GTX 970M or higher version . you gonna have display port..
    other wise....I don't think you could use 144HZ external monitor...even you have it......
    might change to 60HZ.... in the monitor guide will tell you this thing.

    if I am wrong. please forgive me ~
    I research this before....but I give up to buy a high refresh rate external monitor for my razer blade (I7-4720HQ GTX970M, no display port)

    I'm actually waiting for a new Razer monitor to come out or a RE just like this one...

    ^ This is only a 1080 and hope to find at least a 1440 with G sync at 144hz.

    @KönigPanda The HDMI 2.0 was realeased back in 2013, so i would assume 2015 and better would have the 2.0 HDMI port. What version of the Razer blade do you have? @jaseow is right on the bandwidth, and make sure you are plugged in and not using WiFi :)

    Not gonna work for 144hz if you don't have display port. If you have hdmi you only get 60hz :slightly_sad: I tried before.....you have to had display port for a big data transfer (40GB/s) hdmi only have ( 10GB/s)

    I don't have the latest razer blade but the one before it ! Like it has a 1060 gtx but not the latest processor. I hope that it's clear, don't know how to explain it :)

    So are you guys saying that I dont need an adapter and use only use the HDMI cable ? I'm confused, I kinda thought that the HDMI couldn't display 144hz, only the DVI.

    Only DisplayPort 1.1 (I may be wrong here) and HDMI 1.4 support anything over 60Hz for a decent resolution. DVI is a thing of the past, just like VGA and Component AV.

    So much misinformation from people who dont have their facts right in this thread.

    Im going to break it down nice and simple.

    HDMI 2.0 (which is what the blades with the 1060 have) can support up to 18gbps of bandwidth.

    1080p144hz only uses 8.96gbps.
    4k60hz uses 14.93gbps

    Use this site if you want to calculate how much bandwidth your monitor resolution / refresh rate will use.

    https://k.kramerav.com/support/bwcalculator.asp

    If your monitor supports HDMI 2.0 as well then anything below the 18gbps bandwidth will allow it.


    Technically HDMI 2.0 will allow for 1440p144hz as well as that uses 15.93gbps.

    Problem is most graphics card can output that via the HDMI 2.0 port but most monitors only have a HDMI 1.4 port to receive the incoming signal hence why 144hz is not possible.

    Thats where most people online recomment just using a displayport cable to make things less complicated.

    However in the case of the Razer Blade where there is no DP but there is a HDMI 2.0 port, it all depends on the monitor at the end of the day

    Cant see what version HDMI port that monitor has. But if it has HDMI 1.4 which supports 10.2gbps of bandwidth it will allow 1080p144hz that requires 8.96gbps.

    You will be able to use a single hdmi cable to the monitor (assuming its 1.4 on the monitor. Website doesnt say)

    To answer your main question. . .The answer is yes. The thunder bolt port on the Razer Blade 14 can be connected to a 144hz monitor and it will act like a display port. You need to make sure you get a thunderbolt cable though. If you buy a generic usb-c cable it will not work. So just be careful and read reviews on a cable before you buy. The one you listed seemed like a good one.
