Limited Max Resolution (1280 x 720) on HP ZR2740w Monitor

[Tom_Bigott]

Problem: Laptop rebooted and HP ZR2740w monitor no longer recognized high resolution option. Max resolution now 1280 x 720! 

Have been using monitor off docking station on high resolution for years with no problem, have Windows XP 64-bit OS.

Reloaded monitor drivers from original CD that came with monitor without success.  Downloaded and installed drivers from Internet, still does not work properly.

Second monitor (Dell P2210) works fine.

Swapped cables on NEW docking station  (making sure problem not in docking station) and problem remains. 

I originally was using a HDMI cable that went dead on the monitor after reboot; (cable still works fine on other monitors just not the HP), and installed an DVI cable which only works now at 1280 x 720. 

The other DVI cable on a Dell P2210 monitor is working at 1680x 1050 no problem.

How do I correct the low resolution problem with the HP ZR2740w monitor?  This is the second monitor in my organization to have this problem.

Thanks.

Hi,

I have the same problem and I recall reading while ago that this monitor supports only 1280*720 when using DVI connector. Quite a bummer. Unfortunately I cannot find the specs again where I read it.

I had the same issue when I used a normal DVI cable.  Make sure you have a dual DVI cable.  they are green from HP
