I wasn't going to suspect the monitor since you're getting a signal, but I found some information that suggests the HP ZR2740w has a design flaw that requires using a special DisplayPort cable in some cases: http://superuser.com/questions/1003331/h...g-together http://h30434.www3.hp.com/t5/Desktop-Vid...-p/5056327 This mostly affects people using docking stations, but it's possible the same issue affects connecting the monitor to some computers. This only affects DisplayPort. DVI is definitely not affected.

That's why 2560x1440 is not available. Laptops usually don't have dual-link DVI. The 2007 MacBook Pro is a rare exception.

Neither have any luck with higher resolutions on the HP monitor.The Lenovo T430s has switchable graphics, so the Intel GPU controls what resolutions are available. Intel GPUs do not support dual-link DVI, even on desktop computers. (10-04-2016 01:43 AM)onix Wrote: I have a docking station for the T430s that has DVI out. I will have to try that out.Unfortunately, docking stations usually have single-link DVI, and using DisplayPort requires that special cable: https://support.lenovo.com/us/en/documents/ht101460 (solution 4) |
