can t60/x1400 + advanced mini dock use 2560x1440 res.?

[robvarga]

Hi,

I recently purchased an Advanced Mini Dock to my T60 (2007-7KG) having the Mobility Radeon X1400 GPU in it.

I would like to know if anyone successfully used this configuration to drive a monitor with 2560x1440 resolution (via the DVI-D port on the docking station, of course).

The docking station was reported to be able to support it with a T61p.

Question is, would the T60 be able to support it?

When I check the available resolutions in display settings, only modes up to 2048x1536 are displayed in the list, but I do not have a DVI-D cable or a monitor capable of supporting that resolution connected to the docking station.

Has anyone successfully used this resolution with a T60? Would anyone be able to try it?

Depending on this I would either buy a monitor able to support that resolution or one which is only 1920x1200.

Thanks and best regards,

Robert Varga

I am pretty sure it can, esp. since it is listed as supported on the T61. The dock is a simple pass through for the signal, if it has Dual-link DVI pins, it will work, provided that the GPU can output this resolution (and I see no reason why it would not be able to).

I will try to come by a high-resolution monitor to test it on. In the meanwhile, I am pretty sure there exist other members here who may have gotten it to work and can testify.

According to specs: http://support.lenovo.com/en_CY/product ... -62722#vid
the T60 cannot display higher than 2048x1536 on an external monitor.

Thanks for trying but let me emphasize that this is a T60 and not a T61. The dock does indeed have a DVI-D dual link port. Unfortunately I cannot verify if the GPU can output this resolution, as the ATI/AMD webpage does not list the known video modes / resolutions.

The only information in this matter is that the GPU has two 400MHZ DACs according to the ATI/AMD spec sheet:

"- Dual integrated dual-link DVI transmitters
- Dual integrated 10 bit per channel 400 MHz DACs"

Thanks and best regards,

According to the similar sheet for the T61 ( http://support.lenovo.com/en_CY/product ... D=PD008989 ), the T61 cannot display it either, and it has been confirmed at other places to be able drive 2560x1440, so I would take the spec sheet with a grain of salt. The spec sheets for the T6x series has been a long standing source of confusion for what the actual display capabilities for each notebook are.

Regardless of these, thanks for your answer.


Best regards,
