up until recently I was using the U2711 with a Lenovo T410 via a DP output. This allowed me to use the max resolution of 2560x1440. The U2711 is used as my second extended monitor, my laptop screen is my main display.
I now switched laptops to a new Latitude E6520 (with an Nvidia NVS 4200M graphics card) that does not have a DP output nor a DVI output. I was wondering if the HDMI output would allow me to use the max resolution anyway, either via a custom resolution or a cable adapter.
I already tried setting a custom resolution in the Nvidia control panel to 2560x1440 through HDMI. This seemed to work the first time, but whenever I hook up the monitor now via HDMI, the whole laptop becomes unresponsive and the monitor goes into save mode.
So a couple of questions here:
Can I use the custom resolution with HDMI? Would this have any negative impact on the monitor's lifetime/performance?
Can I somehow reset the custom resolution to the native HDMI one in the control panel, as I think this would prevent my laptop from becoming unresponsive?
As an alternative, is there a cable adapter that I could use to go from HDMI to DP or DVI?
