Sceptre C355W-3440UN (35-Inch Curved Ultrawide VA/100Hz/4ms/99% sRGB/HDR400/Budget Pricing) Review
The C355W-3440UN is one of the most affordable curved ultrawide monitors available, built by Sceptre with built-in speakers and a large 35-inch UWQHD panel at a price point well below premium ultrawide competitors.
The VA panel delivers approximately 99% sRGB coverage, a solid gamut result for a budget ultrawide, with select variants of this model also carrying HDR400 certification. 100Hz with a 4ms response time is modest compared to premium gaming ultrawides in this catalog, positioning the C355W-3440UN for casual gaming and productivity rather than competitive esports. Against the LG UltraGear 45GX950A also in this catalog, the Sceptre trades WOLED contrast, higher refresh rate, and 5K2K resolution for a dramatically lower price at a more modest UWQHD resolution and 100Hz refresh rate.
