I am a complete newb with linux but fairly novice with computers in general.

X is meant to default to the highest resolution available.
You could try ctrl+alt+keypad + to cycle through the resolutions, see what happens.
Perhaps edit /etc/X11/xorg.conf to give higher resolution - search up a specimen xorg.conf file on the internet and use that as an exemplar.
The log file /var/log/Xorg.0.log or something along those lines might give a clue.
Perhaps try 'dpkg-reconfigure', with suitable flag or whatever it is called. If it's a Debian based system.

Hi and Welcome !
Which Graphics Card do you have? Set correct driver, Refresh Rates and Resolutions in xorg.conf file.
I am posting generic xorg.conf file. It works fine with most of Monitors and Graphics Cards. Back up existing xorg.conf file and create new.
cd /etc/X11 su - mv xorg.conf xorg.conf.bak nano xorg.conf
Section "Device" Identifier "Configured Video Device" Driver "vesa" EndSection Section "Monitor" Identifier "Configured Monitor" HorizSync 31.5 - 70.0 VertRefresh 50 - 160 EndSection Section "Screen" Identifier "Default Screen" Monitor "Configured Monitor" Device "Configured Video Device" DefaultDepth 24 Subsection "Display" Depth 24 Modes "1280x1024" "1024x768" EndSubsection EndSection

Thanks for the help
Thanks for the response. I will try the new file once I figure out this file structure. I can't seem to find the file xorg file or folder. Can you give me a path (location on drive) to it? Also, what file editor would you recommend, assuming the xorg file will need to be modified?
ps- when i said i was a newb, i really meant it!

Check /etc/X11 folder. Its Capital X in X11.
Rename existing xorg.conf file, if any and create new file.
cd /etc/X11 mv xorg.conf xorg.conf_bak
An easier way, use Gedit. Press Alt+F2 and type this
gksu gedit /etc/X11/xorg.conf
Copy contents from post #3. Save file and reboot machine.

I chose the Gedit method and rebooted after cutting and pasting the monitor code into it. Now I have "Out of Range" 68.7kHZ/85HZ error message on the screen after boot up.
I tried a better quality monitor and also got "unusable signal", or something like that.
Is there a simple was to go back to old setting so as to try another resolution?
btw- my grapics card is a ASUS AGP-V3800 Ultra TNT2
Monitor is an LG model L1734S-BN

Press Alt+Ctrl+F3. Does machine switch to command line mode? If not, boot up in Single User Mode.
Open /etc/X11/xorg.conf file and lower VertRefresh rates.
Section "Monitor" Identifier "Configured Monitor" HorizSync 31.5 - 70.0 VertRefresh 50 - 100 EndSection

got the command line to work- ran nano editor and found vert rate at 160 so changed it to 100. Now it says "permission denied" when trying to overwrite the file.

You must have root permissions to edit xorg.conf file.
Use sudo to gain root privileges.
sudo nano /etc/X11/xorg.conf
