When I loaded up minecraft at first I had the same problem. I think it is using your Integrated Graphics. To Switch to your 1050,
Try this:
"When you open the NVIDIA control panel and add a new program, you should go to "C:\Program Files (x86)\Minecraft\runtime\jre-x64\1.8.0_25\bin\javaw.exe" and add that to the list and make it use your better GPU. I don't know why there's another javaw.exe inside the Minecraft folder." (https://goo.gl/3hzGyS)
To get there either search "Nvidia Control Panel" in the start menu, or Right Click on desktop and select it.
