21:9 · Ultrawide
The ultrawide monitor — big, or fast.
P40K and Q34W are 21:9 ultrawides: the P40K a 40-inch 5K2K canvas, the Q34W a faster 34-inch UWQHD. Built for width, not pixel density — they connect to a Mac over USB-C, but at 139/109 PPI they are not the 218-PPI HiDPI class of our 5K and 6K.

What’s different?
The P40K is a large 40-inch 5120 × 2160 canvas — denser and roomier for serious multitasking. The Q34W is a more compact 34-inch 3440 × 1440, easier to fit on a desk.
Both are smooth, but the Q34W pushes to 165 Hz for crisper motion in scrubbing and play. The P40K runs a steady 120 Hz across its much larger 5K2K panel.
The P40K’s matte Nano IPS panel scatters glare for bright rooms; the Q34W’s glossy coating reads punchier in controlled light.
Why ultrawide
One screen instead of two
A 21:9 ultrawide replaces a dual-monitor setup — all the width, none of the bezel seam down the middle.
Built for wide work
Extra horizontal room for video timelines, wide spreadsheets and side-by-side windows.
Using a Mac?
Both run over USB-C with 100 W charging, but at 139/109 PPI they are not Mac-class HiDPI; the P40K is the sharper of the two. For native Mac-class HiDPI, see the 5K and 6K.
Works with your Mac
21:9 ultrawide over USB-C, DisplayPort or HDMI — plug straight into your Mac’s Thunderbolt or USB-C port. Windows and Linux on capable GPUs too.
Full specs, side by side
7 of 9 specs differ — the same 21:9 ultrawide format, but a bigger, sharper canvas versus a faster, more compact panel.
