BenQ GW2791P 27インチ アイケアモニター Full HD

This article takes a close look at the BenQ GW2791P 27インチ アイケアモニター Full HD: what its specs mean in practice and what to check before you buy.

Overview

The short answer: the BenQ GW2791P is an affordable eye-care monitor for people who want a large 27-inch screen for office work and video while keeping eye strain down. It pairs an IPS panel with Full HD (1920×1080) and a 120Hz refresh rate.

On Amazon.co.jp it was ¥16,470 as of September 2026 (that was the price when we checked, and it changes with sales).

The trade-offs are that resolution stops at Full HD and the stand only tilts. If sharp text or flexible positioning matters most to you, some parts of this monitor won't suit you.

The maker is BenQ Japan. The anti-glare coating keeps reflections down, and the panel covers 99% of sRGB.

Like the rest of this eye-care line, it carries many certifications and features aimed at reducing eye strain: TUV Eye Comfort 3.0, EyeSafe 2.0, flicker-free backlighting, and blue light reduction.

On Amazon Japan it was rated 4.3 out of 5 from 1,927 ratings as of September 2026, a steady average for that many reviews.

What 27-inch 1080p Actually Looks Like

At 27 inches and 1080p, pixel density is about 82 ppi, compared with about 92 ppi on a 24-inch 1080p screen. Each pixel is larger, so text looks bigger and easier to read at default settings, but letter edges look slightly rough up close.

If your desk lets you sit about 60–70 cm from the screen, this is rarely a problem. If your desk is shallow and you sit close, a 1440p model is usually the more satisfying choice.

Flip that around and 27-inch 1080p is a practical match for anyone who wants large text without touching scaling settings. Windows at 100% scaling stays readable, which makes it a sensible pick for a shared family PC or for browsing and spreadsheets at a comfortable size.

Where 120Hz and the Eye-Care Features Help

120Hz redraws the screen twice as often as a typical 60Hz monitor. Cursor movement and page scrolling look noticeably smoother, and you'll notice it when reading long documents, not just in games.

To actually get 120Hz, your PC has to output 120Hz over a port and cable that support it. Monitors often run at 60Hz right after you plug them in, so check the refresh rate in Windows Advanced display settings.

There are five color modes: Standard, Game, ePaper, Care, and Cinema. The idea is to switch by task, such as ePaper for reading long documents, Care for long work sessions, and Cinema for video.

Flicker-free and low blue light modes won't cure tired eyes. Still, a screen that doesn't flicker when you turn the brightness down makes the biggest difference for people who work in dim rooms at night.

Compatibility Guide

The inputs are HDMI and DisplayPort. On a desktop PC, you can connect it to either the graphics card or the motherboard video output.

DisplayPort is the safer choice if you want guaranteed 120Hz. Whether HDMI reaches 120Hz depends on the source device and the cable, so check the product page for supported modes.

For laptops, note that the specs don't list a USB Type-C video input. A laptop with only USB-C ports needs a USB-C to HDMI or USB-C to DisplayPort cable, and the laptop's USB-C port must support video output (DisplayPort Alt Mode).

If you want power and video over one cable, this isn't the monitor for you.

Consoles connect over HDMI. Many console games run at 60Hz, though, so whether you benefit from 120Hz depends on the console and the game.

For variable refresh, the original listing describes the monitor as VESA MediaSync certified. With a compatible graphics card, that reduces tearing (the screen looking split horizontally) and stutter.

Physically, the ultra-slim bezels on three sides make it easy to line up in a multi-monitor setup. The stand tilts only.

The specs list no height adjustment, swivel, or portrait rotation. If you plan to use a monitor arm, check the product page for VESA mount support before you buy.

Product Info

The price on Amazon.co.jp was ¥16,470 as of September 2026.

That's an accessible price for a 27-inch IPS 120Hz monitor. Monitor prices swing a lot during sales, though, so check the product page for the current price.

The Amazon rating was 4.3 out of 5 from 1,927 ratings as of September 2026.

Holding a low-4 average across more than a thousand ratings suggests few buyers found it unusable on arrival.

The standard warranty is listed as three years, and registering after purchase may extend it. The box is listed as including a power cable, an HDMI cable, and a quick-start guide.

Check the product page to see whether a DisplayPort cable is included. BenQ's Eye-CareU software lets you change brightness and modes from your PC instead of pressing the buttons on the monitor.

Recommended Users

• Office and remote workers who spend the day in spreadsheets and documents and have tired eyes by evening
• Anyone who wants large text: 27-inch 1080p stays readable at 100% scaling
• People moving up from a 24-inch 60Hz monitor who want a bigger screen and smoother scrolling
• Hobbyists editing photos for social media or making simple videos, for whom sRGB-accurate color is enough
• Casual gamers who want 120Hz without paying for a dedicated gaming monitor

Before You Buy

The biggest compromise is the stand. It only tilts, so the only way to set screen height is through your desk and chair.

If the screen sits below eye level, you end up craning your neck forward. The eye-care features may protect your eyes while your neck and shoulders pay the price.

If you need height adjustment, plan on a monitor arm or a riser.

Resolution comes next. At 27 inches, 1080p text looks rough up close.

If you code, fill spreadsheets with small text, or tile several windows side by side, a 1440p model of the same size gives you far more working space.

Color needs a note too. 99% sRGB means the panel covers nearly all of the standard color range used on the web and social media.

It is not enough for print color matching or for work that needs wide gamuts such as Adobe RGB or DCI-P3. If you expect professional color management, you'll be disappointed.

For gaming, 120Hz is smooth, but competitive FPS players who want 240Hz or more should look elsewhere. You'll mostly get the benefit of 120Hz on a PC, since many console games run at 60Hz.

BenQ sells several models with similar model numbers, and price comparison sites or store search results can show prices and reviews for a different model. Before you buy, check the product images and the model number GW2791P to make sure it's the monitor you want.

FAQ

Q. Can I adjust the height or rotate it to portrait? A.

No. According to the specs, the stand only tilts.

For height changes, use a monitor arm or riser (check the product page for VESA mount support).

Q. Can I use it with a USB-C-only laptop? A.

There's no listed USB-C input, so you'll need a USB-C to HDMI or USB-C to DisplayPort cable, and your laptop's USB-C port must support video output.

Q. How do I get 120Hz? A.

Connect with a supporting cable (DisplayPort is the safest bet), then set the refresh rate to 120Hz in your PC's display settings. It's common to find it still running at the default 60Hz.

Q. 24-inch or 27-inch at 1080p? A.

Choose 27-inch for larger text, or the denser 24-inch for crisper small text. If your desk is shallow and you can't sit back from the screen, 24-inch is the easier fit.

Q. Does it have built-in speakers?
A. The spec data used for this article doesn't say. If you need speakers, check the product page.
