Our take on the Dell S3425DW
The Dell S3425DW is a 34-inch ultrawide monitor with a 3440x1440 panel, a 21:9 aspect ratio and a 120 Hz refresh rate. It uses a VA panel with a 3000:1 contrast ratio and 300 nits of brightness, and it supports FreeSync for tear-free gaming. Its USB-C input lets a laptop carry video and data over one cable, which puts it ahead of budget ultrawides that offer only HDMI and DisplayPort. It suits people who want one wide screen for work and casual gaming rather than color-critical editing.

Questions and answers
- Is the Dell S3425DW good for gaming?
- Yes for casual and mid-tier gaming. The 120 Hz refresh rate and FreeSync reduce tearing and make motion smoother than a 60 Hz ultrawide. Competitive players may want a faster panel.
- Does it work with a MacBook over USB-C?
- It has a USB-C input, so a compatible laptop can send video and data over one cable. Check that your laptop's USB-C port supports DisplayPort Alt Mode.
- Is 3440x1440 sharp enough at 34 inches?
- Yes. At 34 inches the pixel density is close to a 27-inch 1440p screen, so text stays crisp and you get far more horizontal space.
- Can I mount it on an arm?
- Yes. It uses a standard 100x100 mm VESA pattern, so most monitor arms and wall mounts fit.
- Is it good for photo and video editing?
- It is workable but not ideal. The VA panel and edge-lit backlight favor contrast over color accuracy and uniformity, so color-critical work is better served by an IPS or OLED display.
- What is in the box?
- The monitor comes with its stand and cabling for its inputs. Confirm the exact cable bundle with the seller before ordering.
