If you prioritize an immersive experience for HDR gaming and media, the Gigabyte CO49DQ with its wide color gamut and high contrast may be worth the extra investment. However, if you're looking for a more affordable choice that's suitable for general productivity and casual gaming, the LG 34GN850B will provide you with a quality experience at a lower cost. Keep in mind that the Gigabyte's larger screen and format might not suit all workspaces, and the LG's adjustable stand could offer more ergonomic flexibility. Both monitors have their strengths, so your decision should be guided by your specific needs and budget. Give Feedback

TechSpot
Tim Schiesser | August 2020
"Mid-range 3440 x 1440 144Hz VA monitors are ~$500 to $600 these days. You are getting a much better product for the higher price of the LG, with faster response times and better colors (outside of the contrast ratio), but this is definitely a monitor that is reserved for those that want the best of the best and are willing to pay for it."
