I have asked this question before but got no replies whatsoever. So am asking it again in the hope someone can help me.

When MATLAB encounters a graphics error, I close matlab and start it up again. Upon opening matlab I receive this message on the command line:

Warning: MATLAB previously crashed due to a low-level graphics error. To prevent another crash in this
session, MATLAB is using software OpenGL instead of using your graphics hardware. To save this setting for
future sessions, use the opengl('save', 'software') command. For more information, see Resolving Low-Level
Graphics Issues.

I then type

opengl hardware

to switch to using hardware OpenGL. This returned this error: Warning: Unable to select hardware OpenGL rendering. For more information, click here.

So I type:

opengl info

and receivethis under the hardware section:

HardwareSupportLevel: 'none'

I have attempted closing and re-opening matlab several times now to no avail. There appears to be absolutely no reason for this....

Anybody know how to get matlab to recognise the hardware and therefore switch back to hardware opengl? I am using MATLAB 2017a on a windows machine running Windows 10, 64-bit processor: intel® Core™ i7-6700 CPU @ 3.40GHz, 16GB RAM Seems to have a NVIDIA GeForce GTX 1050 Ti as the display adapter

Many thanks in advance.

Ok I will try seeing if there is any firmware available. Thanks for the tips!!!

I'd probably submit a service request anyway providing details of your system to see if there is anything else TMW might be able to offer; in the other Q? they did point the poster to what they at least thought was latest updates...
