Our Verdict

LG 34UC79G-B

ASUS ROG Swift PG348Q

The ASUS ROG PG348Q is marginally better than the LG 34UC79G-B. The ASUS ROG PG348Q is brighter and has a wider color gamut and better color volume. The 34UC79G-B has better motion handling, with an optional black frame insertion feature to clear up blur, and a higher native refresh rate. The PG348Q has a better stand that can swivel as well as tilt, making it easier to show something to a nearby colleague.
