not sure i understand what you mean about the 19in monitor. If i plan to get a 22in monitor will 720p still look fine on it if i had to resort to it to get good fps?
720p is a screen resolution .
The screen has 1280 pixels by 720
A regular 19 inch widescreen monitor has 1440 x 900
So a 720p screen has 921600 pixels for the graphics card to calculate and draw
The 19 inch monitor has 1296000 pixels to calculate and draw
That means a game would run lower frames per second . or you'd have to turn the image quality down to get the same fps .
The size of the screen is not important . The number of pixels to be calculated is .
Most newer models of LCD screen are 1080p [ though there are exceptions]
A 1080p is 1920 x1080 = 2.073,600 pixels
1080p is a challenging resolution for a Radeon 6770 .
If you are eventually getting a 1080p screen then you will need to consider a more powerful graphics card
