Short summary for : you can either mirror the laptop screen so both displays show the same thing, or use the monitor as a second screen and move the PDF to it while coding on the laptop. For reading a PDF while coding, using the monitor as a second display (extend) usually gives the best readability; mirroring forces both screens to share one resolution and can make the text look small or soft on the larger monitor.

How to set it up (Windows):

  • Physically connect the monitor to the laptop using the matching video connector or an appropriate adapter. Check the shapes of the ports on each device or the laptop manual to pick the right cable/adapter. Some conversions (digital↔analog) need an active converter.
  • Once connected, enable the display mode. The quickest shortcut is Windows+P (choose Duplicate to mirror, Extend to use separate screens). You can also right‑click the desktop → Screen resolution / Display settings → Multiple displays and pick Duplicate or Extend. To make the external screen the main display, select it and check “Make this my main display.”

Troubleshooting and tips:

  • If the monitor shows “no signal,” confirm the monitor’s input source matches the cable, reseat the cable, power‑cycle both devices and try another cable or monitor.
  • Toggle the laptop’s display output (look for a function key with a screen icon), and update the graphics driver from Dell or the GPU vendor if the external display is not detected.
  • If mirrored text looks fuzzy, use Extend and put the PDF on the external screen at its native resolution, then full‑screen the reader for best legibility.
  • As noted, third‑party multi‑monitor utilities exist for advanced window management, but they aren’t required for simple mirroring or extending.

Usually you just need to connect your monitor's vga cable to the laptop vga port and you could download and install an additional tool like Ultramon for dual monitor purposes
