Literally, it means that the OPS computer has a built-in discrete graphics card. Those who have used OPS computers should know that OPS computers are generally divided into two specifications, one is the international universal standard size: 180*119*30mm, and the other is the OPS-C specification, which is mostly used by Chinese manufacturers. The specification is: 180.8*195.2*42.5 mm, then the problem is, the current universal discrete graphics cards on the market, the least specifications are larger than half of the OPS computer, so small OPS computer mainframe, how can it be installed independently What about the graphics card? I originally said that the OPS computer with an independent display is not meant to immediately insert an independent graphics card in it. It is just that NVIDIA's independent display integrated ic is rationally arranged on the same PCB board as the ic design of the computer PC computer motherboard. In this case, the indoor space of the discrete graphics card can be reduced, but the performance of the discrete graphics card can be felt. It's a multitude of things in one fell swoop!
