An alternative suggestion to Curt's is to utilize the kernel's KMS. Curt's suggestion included disabling KMS with either the nomodeset or nouveau.modeset=0 string on the installer's cmdline. Including video=2560x1440 or video=1920x1080 should increase the font sizes without disabling KMS. Including either nomodeset or nouveau.modeset=0 for installation generally means its included in /etc/default/grub and /boot/grub/grub.cfg on the installed system, continuing KMS blockage, and making video performance suffer greatly. Both are intended as troubleshooting workarounds, though traditionally, non-FOSS drivers have required disabling KMS full time. Another key is the i7-6700HQ provides HD 530 Intel video. Intel + NVidia usually equates to "Optimus", which generally means a requirement to follow special instructions for installing either OS or NVidia drivers. These you can find by using Optimus, Prime and Bumblebee as search keywords. Optimus instructions on https://wiki.archlinux.org/index.php/Optimus are reputedly very good, in case any you find for Debian seem inadequate to task. Note too that there are three potentially competent DDX drivers for NVidia, the non-FOSS from NVidia, plus the two from Xorg, nouveau and modesetting. The newer technology modesetting is the upstream default, included in the server package since 4 years ago, but most installations manage to override it by installing all optional DDX drivers via virtual (meta) package, including xserver-xorg-video-nouveau. BTW, upstream's name for DDX drivers takes the form xf86-video-<nameORmodel>, helpful to know in evaluating search results. Having the nouveau DDX installed blocks the modesetting DDX unless explicitly configured not to via /etc/X11/xorg.conf*. IOW, if you purge xserver-xorg-video-nouveau, or explicitly configure its use, before installing NVidia drivers, you get an opportunity to test whether you even need to add the non-FOSS DDX. -- Evolution as taught in public schools is religion, not science.
