I use a 23 inch (1920x1080) monitor, and a 27 inch 1080 LCD TV that work with my eyes, when using the one of the desktop on my home network.
The Acer's C7 smaller screen has a vertical of 768 pixels and I find that limiting. That said I put up with the old fashion 4:3 ratio (1024x768 resolution) LCD monitor for many years. I like the 16:9 ratio, works well with films/video and seldom has black bars on the top and bottom unlike the 16:10/16:11 ratio. The screen ratio is one of the reasons to have one of these wonderful light weight Chromebook systems.
