    HDMI as commonly implemented can only drive 4k at 30Hz.

    You need DisplayPort to drive 4k at 60Hz.


  2. Danchar4 says:


    You're right DisplayPort or HDMI 2.0 is certainly preferred for 4K.

    But you can drive 4K at 60Hz on HDMI 1.4, if you reduce the chroma sampling to 4:2:0 like NVIDIA:…/nvidia-kepler-4k-hdmi-1.4,27117.html

    It looks like crap, but hey its 4K and pixels sell!

    Fortunately, the Intel drivers do not allow those shenanigans

    I am using my Yoga 3 Pro with Windows 8.1 and a Dell S2430L that has 1920×1080 screen resolution. The set up works, but I have to play with the resolution tweek every time I start up the lap top. When I open the screen resolution tool in Windows and identify the monitors it has them shown as opposites. In other words the computer identifies the dell as number 2 monitor but when I identify them it is shown as 1. Does anyone know what this is caused by and a possible solution?

    Just purchased Dell P2416D. Specs say it only can do 2560×1440@60Hz.

    Plugged into my HDMI port Yoga 2 Port and Windows 10 defaulted to the same 3200×1800@59Hz on the dell as well as the Yoga display.

    From what I read, this should not be possible, but works great.


  5. Danchar4 says:

    Bobkat, the Dell screen is not magically running at a higher-than advertised resolution. If you re using screen duplication mode where both screen show the same image, then the Dell screen is just showing the same image as best it can within its resolution constraints.

    You probably already know this, but for others reading this blog, Windows 10 typically defaults to screen duplication mode. So when you plug in the external monitor you see the same image on both screens. You can press the Windows-key+P to bring up the menu to switch to extended mode so you can have one program on the laptop screen and another program on the desktop screen. Many folks prefer to have different content on each screen.

  6. Bobkat says:

    How can I confirm the resolution on each screen? Windows 10 display properties just says recomended res of 3200×1800.

  7. Danchar4 says:

    Bobkat, try running dxdiag.exe. This will give you more detailed information than the pretty control panel. If you click "save all info" within dxdiag you can share your system config information with other folks as well.

  8. Attached Dxdiag text file for DellP2426D+Yoga2Pro says:

    Danchar4, ran Dxdiag with the Dell P2416D external monitor connected to the Yoag2Pro. Looks like you were correct. I was not aware that the Intel HD4400 display drivers in the Yoga could drive two monitors at two different resolutions at the same time.

    With the external monitor running at a lower resolution, shouldn't I be seeing less information on that screen versus looking at the Yoga2Pro screen?

    Hi Bobkat, Here is an old article from Windows Vista about multiple monitors that you may find helpful:…/Understanding-multiple-monitors

    Although the experience much better in Windows 10, the guide is still valid today. You can choose to have the same info on both screens (mirrored/duplication/clone-mode) or have different info on the two screens with extended mode.

    In mirror/clone mode, when the two screens are different size/resolution, like your laptop and monitor, the OS will map one screen to the other so the same information appears. Like in other operating systems, depending on the screens used, there may be some visible side effects of this mirroring approach like anti-aliasing artifacts on certain icons/text or black bars across the top/sides of one of the screens (like letter-boxing when watching a movie). Most of the time these artifacts are not noticeable.

    For desktop scenarios it is recommended that you use extended monitors so that you can have one app on one screen and one app on the other screen simultaneously. Use Winkey+P to bring up the quick menu to switch into extend mode. For beginners, there can be a learning curve in getting used to using two monitors, but after 2 or 3 days, most folks never want to go back to a single monitor.

    You can find many guides online about how to optimize your multi mon setup and if you have further questions

    I recommend you post at as I'm kind of getting out of the scope of what I want this blog to be about.

    Anyway, try extended mode. It will be weird at first, but stick with it for a few days.

    We have gotten the monitor to show decently but every time we connect it or disconnect it the resolution needs to be changed and the computer needs to be restarted. Is there a monitor that has a matching resolution so we don't need to do this?

    Thank you!

    Hi – I am using yoga 3 windows 8.1. I have only ever gotten 1920 X 1080 option with external monitors. I have tried different cables, and different monitors but the result is the same… Any ideas?
