Why it wins: 51.6-inch, 21:9, 4K UHD, 240 Hz official refresh, 320 nits official typical brightness, VA. Official table lists a 240 Hz refresh rate. Official table lists a 4K UHD (5120×2160) resolution.
"Not listed" means the official manufacturer specification table we used does not publish that figure. Prices show "Check price" until a retailer feed provides a current price.
A computer monitor is an electrical display. Use the official stand or a VESA mount rated for the official panel weight, and follow the maker's installation instructions. Place the screen at a comfortable viewing distance, enable the official low-blue-light or flicker-free options if you want them, and give an OLED panel the official pixel-care or screen-saver settings. This site does not test brightness uniformity, burn-in, color accuracy or flicker.

Buying guide: how to choose the right ultrawide monitor
Official size is the first filter
A 34-inch 21:9 panel and a 49-inch 32:9 panel are different desk commitments. We weight official panel size most heavily in this category, then official resolution, official refresh and official typical brightness.
Check the official aspect and the official resolution together
3440×1440, 5120×1440 and 5120×2160 are all ultrawide, but they are not interchangeable. Megapixels are computed from the official pixel dimensions so those differences show up in the score.
Ports matter for the official mode
An official 240 Hz 3440×1440 mode needs a video input that the official I/O table actually lists at that rate. We list official HDMI, DisplayPort and USB-C wording and do not score it.
Curvature is listed, not scored
When the official table lists a curvature such as 1500R, we show it on the product page. It is not a scored field, because not every ultrawide publishes one and flatter panels are a valid preference.
How this ranking is calculated
Score = weighted average of normalised specs, out of 10. Full method
Official panel sizeThe official panel size in inches, which is the main reason to choose an ultrawide. Scale: 29 → 49 inches.
30%
Official resolution (megapixels, computed)Computed from the official pixel dimensions and labelled computed. A 3440×1440 panel is 4.95 MP; a 5120×2160 or 7680×2160 panel is higher. Scale: 2.76 → 16.6 MP.
25%
Official refresh rateThe official refresh rate on the maker's specification table, with the same overclock rule as in the gaming category. Scale: 60 → 240 Hz.
25%
Official typical brightnessThe official typical or SDR typical brightness, not a peak HDR figure. Scale: 250 → 600 nits.
No. Every scored figure comes from an official ASUS, BenQ or LG specification table, linked on the product page. We do not publish prices, ratings or lab measurements of brightness, color or motion.
Why is official typical brightness sometimes Not listed?
We only score a typical or SDR typical brightness when the official table publishes one. Peak HDR brightness is not scored, because makers do not publish it on a consistent method. If the typical figure is missing, we show Not listed and score that field at the category minimum.
What does computed mean next to megapixels?
Megapixels are not usually printed as a single official number. We multiply the official width and height and divide by 1,000,000, then label that figure computed.
Do you score contrast ratio or response time?
No. Official contrast ratios are not comparable across IPS, VA and OLED, and official response-time claims mix GtG and MPRT methods. We list those official figures on the product page and leave them out of the score.
Why might two monitors with the same resolution have different scores?
Resolution is only one field. Official refresh rate, official typical brightness and official panel size also go into the formula. If one official field is missing, that product scores at the category minimum for it.
What counts as an ultrawide on this site?
A monitor whose official aspect ratio is 21:9 or 32:9, or whose official pixel dimensions imply that family (width ÷ height of 2.0 or more). 16:9 and 16:10 monitors are ranked in the gaming or productivity categories.
