I can't get my W540 to output more than 1080 x 1920. It has a K1100M in it, it is driving teh external monitor accrding to the Nvidia Control Panel. I am trying to connect to a Samsung 4K TV.
One active adapter from Startech works, but it seems to be limited to 1080 x 1920. The Nvidia Control Panel only shows drop down choices up to 1080 x 1920 at 60 Hz. I tried 2 other adapters that claim to be able to go to 4K at 60 Hz, but when I hot plug them into the W540 the screen goes black and starts blinking on and off. If I start it up with the adapter connected, the flashing black screen starts as soon as I log on.
