Acer SB220Q bi 21.5" FHD IPS Monitor vs ASUS ProArt Display PA278QV 27" WQHD Monitor
When it comes to display quality, the ASUS ProArt Display PA278QV 27" WQHD Monitor takes the lead with its impressive resolution of 2560 x 1440, compared to the Acer SB220Q bi 21.5" FHD IPS Monitor's 1920 x 1080. This higher resolution means sharper images and more screen real estate, perfect for creative work or gaming. In my testing, the Acer monitor is the budget-friendly option, but the ASUS model offers factory calibration and a color gamut that covers 100% of sRGB. This translates to vibrant, true-to-life colors, crucial for photography and design work. With a brightness of 350 nits versus 250 nits, the ASUS monitor also performs better in well-lit environments, making it a smarter buy for most users in 2026.
