Not very surprisingly this gives the worst results.

My feeling is the GPU is still used in B) scenario but pixel data are block-copied to onboard framebuffer. And not only that, even the GPU temperature and clock frequency were shown in the (b) scenario and they nicely reflected the scenery complexity. On the other hand it displayed GPU parameters and guess which GPU it reported. 0 (4095MB) x1Īpparently the 'combined' mode was the worst. NVIDIA GeForce 940MX 23./Intel(R) HD Graphics 620 22./DisplayLink USB Device. NVIDIA GeForce 940MX 23./Intel(R) HD Graphics 620 22. Then i have restarted it and run third round in standad DL configuration. Then I have attached DL monitor (with benchmark running) and did the second round.

used the personal edition from, first run it on notebook itself. It seems the application when started in 'direct - no DisplayLink' and then switched to DL still uses some GPU functions (and reports itself as using NVidia GPU) but it is switched to the internal board framebuffer.
