    Hello all. So I just got a new Acer Predator XB241H monitor and hooked it to my Razer Blade Stealth +Razer Core/GTX 1070. It works fine enough when I'm duplicating the displays. But as soon as I attempt to show the screen on only the external monitor it begins to lag and visually stutter, almost an unusable amount.

    I attempted to update my Intel Graphics drivers, which alleviated the issue a little bit but did not solve it.

    Then, I contacted Razer Support to which I was told that it was just "a hardware limitation problem," and that I should connect it directly to the Stealth, which I can't do because I need a DisplayPort connection.

    So I was hoping someone on here could be a little more helpful, because I've seen other cases just like mine on here, but no conclusive solutions to the problem.

    Thanks in advance!

    Yup have the same issue here. Tried a multitude of different setups and had a ticket open with support for about 2 months.

    Tried R9 390X / RX 480 / GTX1070 with BenQ XL2730Z and Asus MG279Q 144hz monitors and both would have bad stutter if I only display to external monitor. I have to run my setup in extended mode to get smooth 144hz and no stutter.

    End of the day they said its an issue with Intel side and they offered me a refund with store credit as they have no ETA on a fix

    Never tried this and never will as I need displayport on the gpu to get 144hz. The HDMI on the stealth wont support that.

    Id rather just have to extend display than run on 60hz.

    I wonder if having different refresh rates is causing a problem?

    I've had stuttering issues with monitors (not using the Core) that was the result of having different refresh rates, and similarly didn't have a problem when the display was simply mirrored.

    Edit: I read the initial post wrong, it only happens then the laptop monitor is disabled? That's just crazy. :stuck_out_tongue_winking_eye:

    Yea thats the weird part. If its in extended mode it works fine but if I pnly display on the monitor with the laptop screen blank it stutters.

    The only other fix I found to leave the laptop screen off is to plug in the core AFTER the laptop has booted up. That way it can output to the external monitor without stutter while having the screen on the laptop off.

    But I figured that might cause the connection to become loose or mulfunction if I had to unplug / reconnect the tb3 cable on every bootup and shutdown
  8. I have seen reported that uninstalling the Intel Display Driver has resolved this issue but then of course you are limited to using the Windows default driver when you need to use the Stealth's display.
