@tgd that is a problem of the latest oculus software, i had the same problem and used the older oculus 0.8 runtime. this has to be fixed by oculus… please write to their support. also get the compatibility tool from here: OK | Oculus
also this is interesting:

Apart from the recommended spec, the Rift will require:
Windows 7 SP1 or newer
2x USB 3.0 ports
HDMI 1.3 video output supporting a 297MHz clock via a direct output architecture
The last bullet point is tricky: many discrete GPU laptops have their external video output connected to the integrated GPU and drive the external output via hardware and software mechanisms that can’t support the Rift. Since this isn’t something that can be determined by reading the specs of a laptop, we are working on how to identify the right systems. Note that almost no current laptops have the GPU performance for the recommended spec, though upcoming mobile GPUs may be able to support this level of performance.
so go for HTC vive instead of oculus if you have a laptop…
