It looks like you have an integrated graphics card from ASUS. We're the same, I have a Intel HD Graphics 4000 from Acers website.
How bout try to check for updates with device manager? Heres how
Go to Device manager > click Display Adapters > Click your Intel Graphics Driver > Then click Driver > Then click update driver > Then choose "Search automatically for updated driver software "
Hope this helps.
Updating in this method downloads the latest driver from Intel's site. Then it's same as downloading the driver from intel's site manually.
Just in case you can download the driver for your graphics controller at this link:
If you have problems during the installation try these steps:
I've mentioned before that I installed the latest version of this driver from Intel's site,installed. Then all apps including GPU-z , CPU-Z started to show half of my memory.But windows showed my actual graphics memory (around 1750MB)..But cpu-z and such apps show half..look at the pic below:
But While I installed the older driver provided by Asus.. All these sofwtares showed correct info..See the pic below:
The correct information is the one windows provide. We have received reports from customer where CPU-Z does not show correct information.
Thanks. Then I'm downloading the latest driver from intel.
