    I swapped my m18r2 video card to 1070, but hdmi output only has 1080p, doesn’t support 2k or higher, is there a way to upgrade the hdmi output? My VR helmet only supports hdmi output, but its resolution is 2160*1200, the helmet doesn’t work

    No, but displayport is version 1.2, you can use DP -> HDMI 2.0 adapter to support 4k.

    Actually, I used active DP to HDMI 2.0, but VR helmet does not support DP to HDMI signal. One chip is PTN3460 eDP to LVDS bridge. Can we use this chip to bridge EDP and LVDS screen so that we can directly use the signal of independent video card?

    I am in China, I have bought a adapter like this, and I have bought an active adapter and a passive adapter, but the VR helmet does not support, can not light, contacted the manufacturer, they said that they do not support the DP to HDMI signal.:(

    It's not oculus. It's a brand in China called ANTVR.Are you sure that the DP signal comes from NVIDIA card? Actually, after I changed the 1070 graphics card, the DP output signal can't directly output the resolution of 3440*1440. I need to manually add the resolution in the Intel integrated graphics card settings panel, and the refresh rate can only reach 54 hz.

    You are using a 1070? Then you are limited to DP 1.1 because of nVidia Optimus.

    o_Olinited to Dp 1.1?Omg,Is there any way to change the mode of output, such as using chip to bridge the EDP and LVDS screens, so that independent graphics cards can work independently to output signals?
