<title>Tại sao màn hình trông mờ/nổi cục?</title>

<p>This can happen because the display resolution that you have set it is not the right one for your screen.</p>

<p>To solve this, open the <gui xref="shell-terminology">Activities</gui>
overview and start typing <gui>Displays</gui>. Click on <gui>Displays</gui>
to open the panel. Try some of the <gui>Resolution</gui> options and set the one
that makes the screen look better.</p>

 <title>Khi có nhiều màn hình</title>

 <p>If you have two displays connected to the computer (for example, a normal monitor and a projector), the displays might have different resolutions. However, the computer's graphics card can only display the screen in one resolution at a time, so at least one of the displays might look fuzzy.</p>

 <p>You can set it so that the two displays have different resolutions, but you won't be able to display the same thing on both screens simultaneously. In effect, you will have two independent screens connected at the same time. You can move windows from one screen to another, but you can't show the same window on both screens at once.</p>

 <p>Để thiết lập để mỗi màn hình dùng độ phân giải riêng:</p>

 <steps>
  <item>
    <p>Open the <gui xref="shell-terminology">Activities</gui> overview and
    start typing <gui>Displays</gui>.</p>
  </item>
  <item>
    <p>Click on <gui>Displays</gui> to open panel.</p>
  </item>
  <item>
   <p>Bỏ chọn <gui>Phản chiếu thiết bị hiển thị</gui>.</p>
  </item>

  <item>
   <p>Chọn mỗi màn hình từ ô xám ở đỉnh cửa sổ <gui>Hiển thị</gui>. Thay đổi <gui>Độ phân giải</gui> đến khi chấp nhận được.</p>
  </item>
 </steps>
