Unable to extend display over 2 monitors RRS feed

  • Question

  • So I have looked at the solutions you've provided to people and I am still stuck.

    I have two identical monitors which used to be fine at extended displays on. But with Win 7 PRO whenever I extend the display - it says "Unable to save display settings" - no further info.

    - Both monitors ARE being detected in the display properties and in the correct configuration order
    - I have them connected on a splitter cable (DVI > DVI/VGA)
    - The DVI (Monitor 1) is the primary monitor and works fine
    - The VGA (Monitor 2) is detected but will not extend or duplicate
    - I can switch display between Monitor 1 and 2 and Monitor 2 (VGA) will display - so it is working!!
    - I can't connect the monitors without the splitter as my Video Card only has DVI and HDMI and these monitors do not have HDMI connections

    I have just recently upgraded PC, so I'll give you the specs to help me figure out what is happening and how to fix it.

    OS: Windows 7 PRO
    Monitor 1: Dell1708FB
    Monitor 2: Dell1708FB
    Video Card: Sapphire AMD Radeon Dual-X R90 280 X
    Video Card Driver: AMD Radeon R9 200 Series
    Driver version: 14.301.1001.0

  • I suspect the splitter cable is the problem in terms of how your video card is acting. I would use an HDMI to DVI cable or adapter for one of them and a straight DVI cable for the other.

    Here's one such well reviewed inexpensive item.

  • I'm not sure if Sapphire are pulling my leg but they have replied that;

    "AMD never certified this kind of DVI/VGA splitter cable , the correct connection should as below -
    1. Directly using a DVI to VGA adapter from our card's DVI-I port to VGA monitor.
    2. Directly connecting DVI cable from our card's DVI-D port."

    So even though their pin configuration is of a DVI-I (Dual Link) - it does not operate on a splitter cable.

    I am shocked to say the least but GTS-NJ got it right.

  • Uhm... I am only using TWO monitors as stated, and I am not running a laptop. I said it was a PC.

  • I think that is an easy cop-out of a solution. I have previously used the splitter cable in the past on a Windows system as well as with other video cards.

    I have submitted an IT ticket on the Sapphire support system to check your theory though. I highly doubt they will say their card is not compatible with splitter cables but it is possible.
