Mr. Wielage,
Can you explain what you mean please about the display size and the GUI?
Also, I was under the impression that these high end machines built for creators, and have NVIDIA Quadro dgpu with mDP and can handle files with at least 10 bit out to the external monitor. I was planning on driving with one of these high end machines to an Eizo. I was also planning to shut off the igpu in the BIOS so the dGPU is the priority. Still I have been curious about what panels are being installed on these machines, my original question. If the laptop panels are NG, and I intend to go to an external, why do you think there will be a limitation controlling the color?
