The 6 Best Privacy Screens for 21:9 Ultrawide Monitors, Ranked & Reviewed

Our verdict: A removable pair of 34 inch sheets built for curved 21:9 monitors.

This listing is a pair of removable privacy sheets for 34 inch curved monitors with a 21:9 aspect ratio. It sits in the $100 to $200 bracket, which is the highest price tier here and reflects that two large sheets come in the box.

It ranks first because it addresses the main challenge of the ultrawide category head on: a 34 inch curved panel is wide and bowed, and a filter that ignores the curve can lift away from the glass. The listing states curved compatibility, and a second sheet covers a spare or a twin-monitor desk. Where it loses ground is cost, since the pair lands well above the single-sheet options below.

Buy it if you run a 34 inch curved ultrawide and want a ready spare, or two screens. Skip it if you only need one sheet and want to save money.

Our verdict: A curved 34 inch filter with anti-glare, blue-light and anti-scratch coatings.

The Mamol is a single filter for 34 inch, 21:9 curved monitors, with anti-glare, blue-light filtering and anti-scratch surface features listed. It sits in the $50 to $100 bracket.

Second place is earned because it packs the most surface features of the single-sheet options. Anti-glare helps in rooms with windows, since a filter can otherwise add reflections to an already glossy panel. An anti-scratch layer matters on a sheet you remove and replace often. It trails the top pick only because it comes as one sheet, and blue-light filtering claims are the sort of thing worth treating as a bonus, not a reason to buy.

Choose it for a single 34 inch curved monitor in a bright room. Skip it if you need a spare sheet or the cheapest possible filter.

Our verdict: A 30 inch curved 21:9 filter with anti-glare, blue-light, UV and anti-scratch layers.

The ACONETMAX is sized for 30 inch, 21:9 curved ultrawide monitors and lists anti-glare, blue-light, UV protection and anti-scratch features. It sits in the $50 to $100 bracket.

It takes third place because it is the only listing in this group for the smaller 30 inch class that carries the full set of surface features. Size is the real selling point: 30 inch ultrawides are far less common than 34 inch ones, and their owners have fewer filter options. UV protection is a minor extra for a monitor that never sees sun, but it does no harm. It ranks below the 34 inch picks since those fit the more popular panel size.

Buy it if you own a 30 inch curved ultrawide and want a coated sheet. Skip it if your monitor is a 34 inch, since this sheet will be too short.

Our verdict: A 30 inch filter marketed at gamers, with anti-glare and anti-blue-light coatings.

The APeiSi is another 30 inch, 21:9 curved filter, positioned for gaming monitors and listing anti-glare and anti-blue-light features. It sits in the $50 to $100 bracket.

Fourth place fits, as it matches the ACONETMAX on size and curve, but its coating list is shorter and it makes no UV or anti-scratch claim. A gaming focus is mostly marketing here, since a privacy filter always dims and narrows the image to some degree, which is a real concern for fast games where you want the widest viewing angle and brightest panel. If you game seriously, plan to remove the filter when you play.

Pick it if you want a 30 inch curved sheet and like to switch it off for games. Skip it if your priority is the best surface protection.

Our verdict: A low-cost removable 34 inch sheet with anti-glare and blue-light filtering.

This single 34 inch sheet is sized for 21:9 widescreen monitors and lists anti-glare, blue-light filtering and removable use. It falls in the $25 to $50 bracket, the lowest tier in the ranking.

It ranks fifth because the price is the main reason to choose it. The listing mentions a 21:9 shape but does not say curved, so owners of bowed panels should confirm fit before buying, since a flat sheet on a curved screen may sit loosely at the edges. Removable use is helpful, as you can lift it off for work that needs full brightness.

Buy it for a flat 34 inch ultrawide on a limited budget. Skip it if your panel is curved and you want a listed curved match.

Our verdict: A curved-compatible sheet that publishes an exact 31 1/4 by 13 3/8 inch active area.

The ZYY is a 34 inch diagonal curved-compatible privacy screen, and its listing gives an active area of 31 1/4 by 13 3/8 inches. It sits in the $50 to $100 bracket.

Last place suits it, since the page lists dimensions but little else: no coating details, no pack information and no features to compare against the Mamol. The published measurements are valuable, though, since they let you hold a tape measure to your screen and confirm that the sheet will cover the visible panel without guessing. Many ultrawide buyers skip this check and end up with a sheet that is a few millimeters off.

Get it if you like to verify the size before you buy, and you own a curved 34 inch panel. Skip it if you want a filter with listed anti-glare or anti-scratch layers.
