The product, explained
About the ASUS PG48UQ
ASUS 90LM0840-B01970 is listed in the computer monitors category. The recorded specifications include display diagonal: 120.7 cm (47.5"); display resolution: 3840 x 2160 pixels; maximum refresh rate: 138 Hz. This entry covers manufacturer code 90LM0840-B01970. Specifications relate to this exact source record; other editions or packages may differ.
The 120.7 cm (47.5") display is specified at 3840 x 2160 pixels. Consider these together: a larger screen provides more physical space, while resolution determines the number of pixels available. Neither specification establishes brightness, colour accuracy or motion quality.
The listed maximum refresh rate is 138 Hz. To use it, the source device, cable, resolution and input must all support the intended mode. Refresh rate is separate from response time and input lag.

Check the match
Identify the exact model and the version reviewed. Check the manufacturer code, configuration and supplied accessories.

Where can I compare prices for ASUS PG48UQ?
Use the retailer-offer section on this page for available matched offers. If no offer is shown, we do not currently have a verified price. Confirm model, stock, delivery and the final total at the retailer; coverage does not include every seller.

Not necessarily. Check the laptop port supports the required display mode and charging level.
