Display driver is outdated and it causes problems during playing games.
In such case you will need to download and install drivers from nVidia page… I don’t see other possibility to get other drivers if Toshiba driver page does not provide newer versions…
Also driver that provides "Fn" function is corrupted (Value added package). I have to reinstall that after two months of using, because it stopped working without any error.
VAP (value added package) can be found in the driver area released for other Toshiba notebook series.
VAP is not specific driver/tool so you can choose the newer version released for newer series.
HDMI also does not work properly. When I tried watch movie on TV, screen freezes every 2 seconds.
Don’t think this has something to do with an HDMI driver since there is NO special HDMI driver.
Maybe you should test other HDMI cable or should use other HDMI port of the Tv.
