windows 8.1 - Strange scaling when duplicating monitors with another screen

    I can't get two monitors to scale application resolutions the same way. My main monitor works normally. My second monitor however, which is set to duplicate its image onto a TV I have in my room, renders the applications in a far lower resolution than the 1080p I've set it to. Also, the mouse pointer on the second monitor is enormous, it looks 2-3 times bigger than the one on the main monitor.

    I've checked the "Let me choose one scaling level for all my displays", to no avail. Here are some comparison pictures.

    Metro on the main monitor:

    Metro on monitor 2 (set to 1080p and to duplicate on a TV):

    image2

    And here's comparison pictures of the mIRC program on the two monitors:

    and then

    image2

    As you can see, the mIRC window is MUCH bigger on the secondary monitor, cause of how weird the scaling is.

    I use a single Geforce 660 GTX and the OS is Windows 8.1. The monitor is a BenQ G2420HDB, the TV is a Samsung UE46F5005. This issue only seem to arise when I duplicate the monitor onto the TV.
    Does anyone have any idea of how to solve this?

    Can't be fixed. You can't scale 2 monitors differently. Down size the res of your highest monitor or buy 2 that match.

    By having a check box that says "Let me choose one scaling level for all my displays" it implies there is another option. There is not. It does not work.

    windows 7 - 2 monitors + HDMI LCD Screen
  • Nick Udell

    I currently have an nVidia GTX 480, with two DVI ports and one HDMI. I have the two DVIs plugged into 1680x1050 resolution monitors and the HDMI into a 1080p HD TV.

    Currently Windows7's screen resolution tool will only let me have one monitor + TV or 2 monitors and no TV showing extended desktops at a time. Is this a software or hardware limitation?

    If I get better multi-monitor software will I be able to extend my desktop across all three screens?

    You can connect 3 monitors, but one will be disabled. The point of having the 3 ports is to give you options, so you can choose between using DVI or HDMI. Here's a quote from a thread on the NVIDIA forums when someone asked about multiple monitors on the GTX 480

    For graphics cards which have a single GPU onboard like the Geforce GTX 480 or 470, only two displays can be active at the same time even if the card has three physical monitor connectors. Some cards like the older version of the Geforce GTX 295 have two GPUs onboard and three display connections, two DVI and one HDMI. The first two ports, the two DVI ports are connected to the first GPU and the HDMI port is connected to the 2nd GPU. So in this case, three monitors could be supported as long as the card wasn't set to "multi-GPU" mode. But for pretty much every NVIDIA graphics card, you will only be able to activate two monitors at the same time.

    This is a hardware limitation. I suggest purchasing a cheaper card like a GT 220 and putting that in to add more monitors.
