I've just setup my triple monitor configuration here at work and am running into some snags with one of the monitors.
Two of the monitors are identical, but one of these two (the one running off of the DisplayPort) is not reaching maximum resolution.
My primary monitor, connected via DVI, is set to 1680x1050. The secondary monitor, connected via DisplayPort and adapter, cannot go beyond 1440x900. The tertiary monitor, connected via VGA, is fine at 1024x768.
- 2x Dell 2009w monitors
- Elo ET1529L monitor
- XFX ATI Radeon HD 5450 video card (HD545XZAF2)
- Accell B087B-005B UltraAV DisplayPort to DVI-D Single-Link Active Adapter
I've found that if I disconnect the tertiary monitor and connect the secondary via VGA it works fine at 1680x1050. It is limited to 1440x900 connected via DisplayPort with or without the tertiary monitor.
Any ideas on how to get this second monitor at the correct resolution? I'm wondering if it is my adapter. I thought that the DisplayPort to DVI adapter was supposed to be ok up to 1920x1200.
