I have been given a replacement monitor for my CentOS-6.3 KVM test platform. It is an LG E2251 22in letterbox format screen whereas the unit it replaces was a 17" standard format display. The console messages now look as through they were output on Silly Putty.
The display itself displays a message to set the resolution to 1920 x 1080. I have found references to using the vga option in the grub.conf file. However, I can find no comprehensive list of what value to use. The references I have found actually say "see the source code in the Linux kernel tree", which does not strike me as particularly "user friendly" shall we say.
How do I do this or am I condemned to rubber band output.

Are you talking about a CLI display boot resolution or a GUI display setting in X?
If CLI, use this table:
So, I located the Kernel source documents or something approximating same:
http://www.kernel.org/doc/Documentation/svga.txt
From this I gather that I probably have to reboot the system to
discover what mode to use. Is there another way of getting this info once the system is started?
http://www.kernel.org/doc/Documentation/fb/vesafb.txt
From this I read:
Advantages:
* It provides a nice large console (128 cols + 48 lines with 1024x768) without using tiny, unreadable fonts.
Now, I would really like to get back to an 80x24/26 cli console display, preferably centered on the new monitor. Is this possible? I would also like the font to be a bit larger, how is this done?
Is it true, as I have been told, that one can no longer purchase a 'standard' form factor flat panel monitor? That they only make widescreens now? Really???
