Post subject: | Trouble using all my 3 screens. |
Heya! Found this forum a few days ago and been reading it nonstop since but i havent managed to find a solution to my problem. Here is my setup: 5850 BenQ 24" 2420HDB 1920 x 1080 BenQ 22" E2200HD 1920 x 1080 Samsung Syncmaster "17 1280 x 1024 I know the last screen is a few years older but still wanted to atleast have it activated in 2D. I use DVI on my 2200 and my Syncmaster. The 2420HDB is powerd with an DP > Passive DVI adapter and works flawlessly ( Note that i can only get this screen working with the adapter the 22 and the samsung wont work ) I use the 9.12 Drivers ( The hotfix ) and in "Desktops and displays" in the CCC i see all three screens and everything seems fine. I Have no problem running two screens, all setups work there. However i can get the 3th activated. I cant extend it but only if iam using only one screen. When i try to make a displaygroup i only get the option using 2 x 1 screens. Been googling around and serching this forum but i cant seem to find a solution. Anyone have tips on what to do? Ceogar :) |

If I read this right, you can only get 2 screens at anyone time to work. I feel it is because the passive adapter requires the use of one of the internal clocks that DVI needs to work. You can do something to alleviate this: 1. Buy a DP monitor. 2. Buy and Active DP->DVI Adapter (You might also have to flash the Video Card) 3. Buy a DP->VGA adapter, the conversion doesn't require a clock as it generates one in the adapter. Sorry, there's nothing free on the list but the 3rd option is the cheapest at about $30 if you don't mind an analog signal. BTW, Also with the different resolutions, the highest Eyefinity group you can make with your set of monitors is 3x1280x1024. |

that 3rd screen will kill your options on resolution. |

that 3rd screen will kill your options on resolution. only if you don't use a EDID mask or go above VGA's Bandwidth, Which that wont happen with those monitors. Just remember in Eyefinity mode, the highest res you can get is 3840x1024. |
