Mining with specified graphic card

[tbonetony]

Hi folks,

I have a question regarding mining with a specified GPU. Currently my build is for entertainment and casual mining. I would like to use the embedded Intel graphic card (hooked up with a monitor) for watching video and the Asus R9 280X for mining.

I was getting errors with sgminer 5.1.1 while using the above setup:
------------------------------------------
ADL found less devices than opencl!
There is possibly more than one display attached to a GPU
Use the gpu map feature to reliably map OpenCL to ADL
WARNING: Number of OpenCL and ADL decices did not match!
Hardware monitoring may NOT match up with devices!
-------------------------------------------

I can only mine with 280x while my monitor is connected to it. Below is the configuration I use:
"device":"0",
"gpu-platform" : "1",
"xintensity" : "14",
"keccak-unroll" : "0",
"hamsi-expand-big" : "4",
"algorithm" : "ckolivas",
"lookup-gap" : "2",
"worksize" : "256",
"thread-concurrency" : "8192",
"gpu-engine" : "900-1070",
"gpu-memclock" : "1400-1600",
"gpu-fan" : "20-75",
"gpu-powertune" : "20",
"temp-cutoff" : "90",
"temp-overheat" : "75",
"temp-target" : "70",
"gpu-threads" : "2",
"auto-fan" : true,
"auto-gpu" : true,
"failover-only" : true,
"failover-switch-delay" : "300",
"queue" : "1",
"api-listen" : "true"

Notice that without gpu-platform:1 it would not run.

Thanks for your input.
