Buying Guide: How to Choose the Best Monitor Arm for 34 Inch Ultrawide
Keep these factors in mind when shopping for the best monitor arm for 34 inch ultrawide.
Screen size and arm reach
Larger screens need longer arms and stronger springs. Ultrawides around 34 inches and super ultrawides at 49 inches need heavy-duty arms rated for their weight and width.
Check VESA and weight
Most monitors use a 75×75 or 100×100 mm VESA pattern on the back. Confirm the arm’s weight range covers your monitor, including curved or OLED models that may be heavier than they look.
Gas spring vs. mechanical spring
Gas spring and mechanical spring arms both let you move the screen with one hand. Mechanical springs, like Ergotron’s, last a long time; gas springs are common on budget arms. Tension must match your monitor’s weight.
Set the right monitor height
Place the top of the screen at or slightly below eye level, about an arm’s length away. An arm makes it easy to adjust when you switch between gaming and work.
Ultrawide Arm Tips
Mount wide screens:
- Center the arm on the screen.
- Check curve depth vs. desk depth.
- Set tension for the full weight.
- Use two people to mount.
