Our Verdict
Samsung C49HG90/CHG90
ASUS ROG Swift PG348Q
The ASUS ROG PG348Q and the Samsung C49HG90/CHG90 are similar overall monitors, each with their advantages. The PG348Q has a better stand with better ergonomics, and it has much wider viewing angles. The CHG90 has flicker in the backlight, and it has an optional mode to reduce the flicker frequency to reduce persistence blur. The CHG90 also has a higher refresh rate. The PG348Q supports G-SYNC, whereas the CHG90 supports FreeSync. This may be an important factor to take into consideration depending on what your graphics card supports.
