Buying Guide: How to Choose the Best Portable Monitor for ROG Ally

Keep these factors in mind when shopping for the best portable monitor for rog ally.

Handheld PCs like the ROG Ally

ROG Ally and similar handheld PCs output video over their USB-C port, so a portable monitor with a full-function USB-C input can take video and, with passthrough charging, power from one cable. Use the charger that came with the handheld for the most stable power.

Do you need 144Hz or 240Hz?

A 60Hz screen is fine for consoles locked at 30 to 60 fps and for work. 120 to 144Hz makes laptop, handheld and PS5 or Xbox games at 120 fps feel smoother. 240Hz only pays off with a strong gaming laptop in fast shooters. Your device must actually output the higher refresh rate over the cable you use.

Powering a portable monitor

Over HDMI the monitor needs power from a USB-C wall charger, usually 18W to 30W or more for bright or high-refresh models. Many monitors also offer power passthrough, so one charger can power the monitor and charge your laptop or handheld at the same time.

1080p, 1440p or 4K on a small screen?

1080p looks sharp on 13 to 16-inch panels and is the easiest resolution for consoles, handhelds and laptops to run at high frame rates. 2.5K (2560×1440 or 2560×1600) adds clarity for text and games on 16 to 17-inch screens. 4K looks crisp on 15 inches and up, but most consoles and laptops cannot run demanding games at 4K and a high frame rate.

Portable monitor setup tips

Set it up right:

• Use the cables that came in the box first.
• Set the refresh rate in Windows display settings.
• Use a USB-C charger with at least the wattage the listing recommends.
• Raise the screen closer to eye level with a stand.

Here are quick answers about the best portable monitor for rog ally.
