Abstract

Disclosed are a computer system and a control method thereof. The computer system can include a graphic unit to generate and output an image signal, a connector to which a display to display an image based on the image signal is connected, a user input unit to receive an input, and a controller to identify the display, determine whether to adjust a resolution of the image, change the resolution of the image for resolution adjustment of the image to be displayed, and control the graphic unit to display the image based on the resolution of the image selected by the user. With this configuration, a user can easily adjust an image resolution.

Claims

1. A computer system comprising:

a graphic unit to generate and output an image signal;

a communication interface to communicatively couple a display to display an image based on the image signal;

a user input unit to receive an input; and

a controller to determine whether to adjust the resolution of the display with the controller of the computer system, change the resolution of the image and display the changed resolution image on the display at least once, and receive an input to select the changed resolution image as a set resolution to display images on the display.

2. The computer system according to claim 1, wherein the controller successively changes at least one of a horizontal resolution and a vertical resolution of the image at a predetermined interval.

3. The computer system according to claim 1, wherein the controller independently changes the horizontal resolution and the vertical resolution of the image, displays the changed horizontal resolution and vertical resolution, and adjusts at least one of the horizontal resolution and the vertical resolution and then the other.

4. The computer system according to claim 1, wherein the controller simultaneously changes the horizontal resolution and the vertical resolution of the image and displays the changed horizontal resolution and vertical resolution.

5. The computer system according to claim 1, wherein the controller receives display-related identification information from the display and identifies the display based on the identification information.

6. The computer system according to claim 5, further comprising:

a storage to store the identification information,

wherein the controller stores the resolution of the image selected by the user in the storage in association with the identification information.

7. The computer system according to claim 5, wherein the identification information includes EDID data.

8. The computer system according to claim 1, wherein the controller identifies the display based on at least one of resolution, clock, and image size of the display.

9. A method of displaying an image on a display that is communicatively coupled to a computer system, the method comprising:

determining whether to adjust the resolution of the display with a controller of the computer system;

changing the resolution of the image and displaying the changed resolution image on the display at least once; and

receiving an input to select the changed resolution image as a set resolution to display images on the display.

10. The method of claim 9, wherein the changing the resolution of the image includes changing at least one of the horizontal resolution and the vertical resolution.

11. The method of claim 10, wherein at least two images are displayed on the display having different horizontal resolutions or different vertical resolutions.

12. The method of claim 9, wherein the changing the resolution and the displaying of the changed resolution on the display are at predetermined time intervals.

13. The method of claim 9, further comprising:

identifying the display that is communicatively coupled to the computer system; and

storing the set resolution in a storage unit with information of the identified display.

14. The method of claim 9, wherein the determining comprises identifying the display based on at least one of resolution, clock, and image size of the display.
