30 inch screen on Radeon Mobility X1300 video card: impossible?
Last response: in Graphics & Displays
My IBM Thinkpad T60 has a Ati Mobility Radeon X1300 video card and I'm trying to use it to drive a 30 inch HP screen (a HP LP3065) at 2560x1600.
From browsing these forums I discovered I needed at least the Advanced Mini Dock to provide dual-link DVI output to drive this beast so I've got that but I can only drive it at half its real resolution 1280x800 instead of 2560x1600. This screen only provides full resolution or exactly half - there's no scaling.
Can I get this video card to display at the full 2560x1600 resolution?
I've tried disabling the main laptop LCD so it could provide some oomph to the external 30" HP one but Windows and the ATI Catalyst Control Ctr refuse to list the full-res mode. Is it there anything I can do? I prefer not buying a Advanced Dock and fitting a desktop PCI-E video card - too expensive. I would very possibly consider a motherboard upgrade (=video card upgrade) if it was the only way to go and not too expensive and would definitely work.
Here are the spec of the Ati Mobility X1300 (note its the mobility edition, not the PCI-E one):
Driver version: 7.01.01.646
Identity: ATI Display controller
Memory clock: 319.50 MHz
Engine clock: 391.50 MHz
IRQ - (n/a)
PCIe version - 1.00a
PCIe link rate - x16
Display driver - atiumdag atiumdva atiumd64 atiumd6a atitmm64 4
DirectX driver - atiumdag.dll, v.7.14.10.0503
It has only 64 dedicated RAM but apparently it can grab some off the system RAM (3GB) when it needs to.
Anyone have any ideas?

How are you plugging it into the screen? As you said you need the mini dock so that you have the dual link DVI. I suspect your laptop if it has DVI only has support for single link, which doesn't provide enough bandwidth for 2560x1600.
If you do get it to work it should be fine for movies and such. Not a chance for modern or semi modern games.

I have the Mini Dock which provides a dual-link DVI. I don't want it for gaming, just regular work but at full 2560x1600 resolution. Help!
