Smaller screen after installing radeon driver from AMD's site
Solution 1
Try setting Catalyst Control Center Scaling Options to 'Overscan 0%' and see..
Solution 2
Use this command, it should work:
sudo aticonfig --set-pcs-val=MCIL,DigitalHDTVDefaultUnderscan,0
I have a how-to on my blog, www.ligti.se.

I don't know if this is fully Ubuntu related, anyway here's the question:
After I put in AMD Asus 280X and booted the screen size was normal, but after I downloaded and installed AMD's original 14.4 Linux drivers
amd-catalyst-14-4-linux-x86-x86-64.zip
, restarted and booted again, it still was full HD but the screen size is like one inch on every side smaller/compressed. It's like as if you open up an image and scale it to 90% or so, you still see everything but you can see if there were text that the text is not in its original size (kind of blurred). (My LG Flatron IPS234 is connected via HDMI with the graphics card, Ubuntu 14.04 64bit)Here is an image which shows what I mean (note: the camera made this image extreme blurry, in reality it's just a bit blurry):

Bibi424 over 9 yearsDid you checked screen resolution in display settings? goto All settings>Displays Check screen resolution is set correctly....also check resolution settings in ati catalyst
-
user279779 over 9 yearsUnder the Desplays settings it says it is a "Goldstar Company Ltd 23"" and the shown resolution there is "1920 x 1080", which is correct, but the display name is not correct. Under catalyst it shows "1. IPS234" and "1920 x 1080", which is correct.

Bibi424 over 9 years1. Catalyst Control Center 2. Graphics 3. Desktops and Displays 4. Right click the display that has the incorrect displayed area. There will be two if there is another device added (like a tv). 5. Configure 6. Scaling Options 7. Slide the arrow to the right "Overscan to 0%".

user279779 over 9 yearsI got it!: 1. from amdconfig I got the display types "The DISPLAYTYPE in options can be one of the following strings: crt1, lvds, tv, cv, tmds1, crt2, tmds2, tmds2i, dfp3, dfp4, dfp5, dfp6 ." 2. Then I used the script from ubuntuforums ?t=2064230 and tried the types until the type dfp5 worked :) It's basically these four lines aticonfig --set-dispattrib=$DISPLAY_TYPE,positionX:0 aticonfig --set-dispattrib=$DISPLAY_TYPE,positionY:0 aticonfig --set-dispattrib=$DISPLAY_TYPE,sizeX:$WIDTH aticonfig --set-dispattrib=$DISPLAY_TYPE,sizeY:$HEIGHT

Eliah Kagan over 9 yearsWhich post on your blog is the howto that contains that code/command? Searching the ligti.se domain for it with Google doesn't turn up anything. Also, you may want to edit this answer to explain what that command is doing.
