FIX: NOX Player Black screen Startup


👉 Assuming that you already opened your NOX Player and already experiencing a black screen, click Settings (Gear icon) of your player or emulator.

👉 In the System settings, under General settings menu, check Root in Startup items.

👉 Now click the Performance settings. Change it to Custom. In CPU and MEMORY, see the tutorial below to know how to setup yours. For the Graphics rendering mode, Basic Mode (DirectX) worked for me so I selected it.

👉 To know your CPU, right-click your Taskbar. In the menu that will appear, click Task Manager. You can also go to search, type taskmgr and press Enter.

👉 In the Task Manager, click the Performance tab and look for the Cores. In my example below, I got 2 cores. So, in the Cores, I typed 2.

👉 To know what to put in MEMORY. Open My Computer/This PC. Right-click its icon and then press Properties. Or, you can open search and type msinfo32, then press Enter key. Under System summary, find Installed Physical Memory (RAM). You can also press Windows key + Pause/Break key simultaneously. In the System find Installed Physical Memory (RAM) also.

👉 Find System then, see Installed memory (RAM). For this tutorial, I got 8 GB which is equivalent to 8192 MB. But I only used 4 GB which is equivalent to 4096 MB (see table below).
👉 Now, if you only have 2 GB, then use 2048 MB, 3072 for 3GB and so on. Just remember that 1 GB is equivalent to 1024 MB. So if you have 5 GB that is 5 x 1024 = 5120 MB.


👉 When you already changed your Performance settings' CORE and MEMORY, click the Save settings button > then click Restart.

👉 Done!
