    VRAM limitation at 1920x1080 display resolution setting


      I implemented some code with OpenCL on AMD Radeon R9 Nano environment.

      I encountered memory problem only at 1920x1080 display resolution setting.

      Nano has 4GB VRAM, but vram allocation seems to be limited up to around 1.5GB only at 1920x1080.

      When I run the code, gpu crash after OpenCL kernel setting, and VRAM usage is about 1.5GB at the time.

      OpenCL's return value is -4(CL_MEM_OBJECT_ALLOCATION_FAILURE)

      Except 1920x1080 setting(ie.1920x1200 or 1280x720...), no problem with memory allocation above 1.5GB.

      Is there any limitation in 1920x1080 display resolution setting ?
