Hi, I'm new to linux. I just installed fedora 27 but screen resolution is very low. My LCD screen size is 21 inch and still screen looks fizzy. I have set maximum(1024x768) Screen resolution option. I used to set high resolution on windows on same LCD for good display but in fedora, I don't have option for setting resolution more than 1024x768. How can i set resulation higher than 1024x768.

Thanks in advance.

What graphics chipset do you have? Check the output of lspci for lines with VGA or Graphics in them. If the max resolution is 1024x768, that means that the driver isn't available or working for that one.

This is what I'm getting when i ran "lspci".

It also depends on the monitor itself. More specifically, the EDID information the monitor sends to the graphics adapter.

monitor-get-edid | monitor-parse-edid can read out that information, but there is a small syntax error you have to fix first on line 735 in /usr/bin/monitor-parse-edid

It's an Intel graphics chip and not a really new one, so it should be fine. What is the output of cat /proc/cmdline? Try not using Wayland. When you click on your name to login, before you enter the password, there is a little gear icon. Click on it and select "Gnome on Xorg", then enter your password to login. See if that helps.
