How sharp is a 45-inch 3440 × 1440 ultrawide? PPI explained

By TechCompare · Updated · How we check

83 PPI is what 3440 × 1440 gives at 45 inches (114.3 cm), and single pixels stop being visible at 41 inches (105 cm) away. That's less dense than the 34-inch version of the same grid.

A 45-inch 3440 × 1440 ultrawide works out to 82.87 PPI, with 4.95 million pixels spread over 721 square inches (4653 cm²). Its density sits below the 34-inch version of the same grid, at 110 PPI, and that's the trade you make for the extra width.

How this is calculated

Retina distance is 41 inches (105 cm), and inside that distance the pixel grid shows on text and edges. According to LG's UK spec page for the 45GR95QE-B, this is a 45-inch OLED curved gaming monitor at 3440 × 1440 with an 800R curve and a 240 Hz refresh rate.

Verdict

A 45-inch 3440 × 1440 ultrawide suits wide canvases and multi-window work, where you sit back from the screen. The panel measures 41.5 inches (105.4 cm) wide and 17.4 inches (44.1 cm) tall, with 4,953,600 pixels across 721 square inches (4653 cm²). Text is less sharp than on the 34-inch version, so the extra width comes at the cost of fine detail.

Frequently asked questions

Is a 45-inch 3440 × 1440 monitor too blurry for text?
Not from a distance. Single pixels stop being visible at 41 inches (105 cm) away, but up close the grid shows on text. At 83 PPI it's less sharp than a 34-inch 3440 × 1440 panel.
Is a 45-inch ultrawide the same as a 34-inch 1440p ultrawide?
They share the 3440 × 1440 grid, so the pixel count is the same. The 45-inch panel spreads those pixels over a bigger screen, so its density is lower.
How wide is a 45-inch 3440 × 1440 monitor?
About 41.5 inches (105.4 cm) wide and 17.4 inches (44.1 cm) tall, a 43:18 shape. Measure your desk width before you buy.
