Know before you buy

Judge sharpness by pixel density, not resolution alone. A 27-inch 4K screen is about 163 ppi, 27-inch WQHD about 109, 23.8-inch full HD about 93 and 27-inch full HD about 82 — calculated from resolution and screen size.
Check your laptop charger’s wattage and choose a monitor that delivers as much or more. The five supply 65 W to 90 W over USB-C; of the ten we scored, only I-O DATA’s LCD-CU273AS-FX reaches 90 W.
Height ranges run from 130 mm to 191.2 mm across the five. EIZO’s EV2490 rises furthest, high enough to sit your laptop underneath as a second screen. All five also turn to portrait.
Wired LAN through the same USB-C cable is rare: only the EIZO EV2490 among the five. The runner-up I-O DATA LCD-CQ271SA-FX has a LAN port too, but its LAN works only with Windows 10 and 11.
Warranties differ more than prices: five years for three of the five (within 30,000 hours of use), three years for Dell with advance exchange, and three years for BenQ but only one on the panel and backlight. JAPANNEXT offers two.
Rakuten reviews are thin for monitors — 0 to 11 per model even across the top 30 listings — so trust is scored on the warranty instead.

A screen of 23.8 to 27 inches
Video input over USB Type-C, supplying a connected laptop with up to 65 W or more

Scoring

Five criteria, one to five stars each, weighted to one hundred points. Every star says where the number came from.

Quality25 pts
- Set by pixel density, calculated from resolution and screen size: 27-inch 4K, about 163 ppi, five stars; 27-inch WQHD, about 109 ppi, four; 23.8-inch full HD, about 93 ppi, three; 27-inch full HD, about 82 ppi, two. All ten models compared use wide-viewing-angle IPS-type panels (IPS or AAS), so the panel type makes no difference to the score.
Value for money20 pts
- The lowest Rakuten Ichiba price, new and monitor only: under ¥35,000 five stars, ¥35,000 to under ¥45,000 four, ¥45,000 to under ¥55,000 three, ¥55,000 to under ¥70,000 two, ¥70,000 or more one.
Easy to live with25 pts
- Starts at three stars. Add one if USB Type-C delivers 90 W or more, one if the stand adjusts 150 mm or more in height, and one if a laptop connected over USB Type-C can use wired LAN; subtract one if the height range is under 100 mm (five at most, one at least).
Trust15 pts
- Rakuten reviews total only 0 to 11 even across the top 30 listings for each model number, so the stars are set by the maker’s warranty: five years, five stars; three years with the panel and backlight also covered for three, four; three years with the panel and backlight covered for one, three; two years, two.
Only here15 pts
- Starts at three stars. Add one or two where a figure or feature belongs to this model alone among the ten compared, and where it bears directly on working from home — the work itself, the cabling or video calls.

What we dropped

Candidate	Verdict	Why
I-O DATA 27-inch WQHD monitor (LCD-CQ271SA-FX)	Runner-up (85/100)	85 points, above four of the five, but it is the LCD-CQ270SA-FX with a LAN port added, at ¥5,760 more (¥43,560 against ¥37,800); its LAN works only with Windows 10 and 11, and wired LAN through one cable is already among the five in the EIZO EV2490. No figure of its own among the ten.
JAPANNEXT 27-inch WQHD monitor (JN-IPS27Q2-HSPC6)	Runner-up (73/100)	73 points, above only the BenQ GW2486TC among the five. The 27-inch WQHD slot goes to the LCD-CQ270SA-FX, which costs ¥6,820 more (¥37,800 against ¥30,980) but rises 150 mm against 110 and carries five years’ warranty against two.
LG UltraFine 27U730B-B	Runner-up (72/100)	72 points, above only the BenQ GW2486TC among the five. Its 80 mm height range loses a star and no portrait rotation is listed; the LCD-CU273AS-FX fills the 4K slot for ¥4,240 more (¥43,040 against ¥38,800) with 150 mm of height, 90 W and five years’ warranty.
JAPANNEXT 27-inch 4K monitor (JN-IPSB27U-HSPC6)	Runner-up (71/100)	71 points, level with the BenQ GW2486TC. The LCD-CU273AS-FX fills the 4K slot for less (¥43,040 against ¥43,979), with 90 W against 65, 150 mm of height against 140, and five years’ warranty against two.
BenQ GW2786TC eye-care monitor	Runner-up (62/100)	62 points, the lowest of the ten. The 23.8-inch GW2486TC has the same microphone, 65 W, 100Hz and 130 mm of height for ¥3,635 less (¥31,787 against ¥35,422), with sharper text at about 93 ppi against 82.
BenQ RD270Q	Runner-up	27-inch WQHD at 144Hz, 65 W charging and 130 mm of height meet every condition, but it is built around display modes for programming, and its new price on Rakuten is in the ¥50,000s — more than the LCD-CQ270SA-FX at the same WQHD, with a three-year warranty that covers the panel and backlight for one.
EIZO EV2795	Outside the theme	27-inch WQHD, 70 W charging, 176.6 mm of height and a five-year warranty, but the lowest new price on Rakuten is ¥79,800, over ¥60,000 (condition 5).
EIZO EV2740X	Outside the theme	27-inch 4K, but the lowest new price on Rakuten is over ¥100,000 (condition 5).
BenQ PD2706QN	Outside the theme	27-inch WQHD with 90 W charging, but the lowest new price on Rakuten is ¥63,000, over ¥60,000 (condition 5).
Dell U2724DE	Outside the theme	New listings on Rakuten start in the ¥70,000s, over ¥60,000 (condition 5).
Dell P2425HE / P2425E / P2725HE	Outside the theme	No new unit that an individual can buy on Rakuten — only used, business-only or outlet listings (condition 5).
LG 27UP850N-W / 27QN880-B, EIZO EV2781	Outside the theme	No new unit on Rakuten — only used items or screen-protector films (condition 5).
iiyama ProLite XUB2497HSN-B2	Held back	Retailers outside Japan list it as 23.8-inch full HD with 65 W charging and 150 mm of height, but we could not find a specification sheet on iiyama’s Japanese site (condition 4).

Questions visitors ask

Which of the five should I choose if I can’t decide?

The I-O DATA LCD-CU273AS-FX, a 27-inch 4K monitor. Its total across the five criteria was 96 out of 100, the highest of the five.

Which is the cheapest, and how current are the prices?

The BenQ GW2486TC, at about ¥31,787. Prices are typical selling prices including tax, checked on the makers’ sites and Rakuten Ichiba in late October 2026 (Rakuten on 26 October). They move with campaigns and stock, so check the link before you buy.

Where can I buy one?

All five are sold on Rakuten Ichiba, which ships within Japan, and the links above go straight to the listings. The Dell S2725QC is also sold on Dell’s own store, at ¥47,979 when we checked — less than its lowest Rakuten price of ¥52,800.

Full HD, WQHD or 4K?

Compare sharpness by pixel density: a 27-inch 4K screen is about 163 ppi, 27-inch WQHD about 109, 23.8-inch full HD about 93 and 27-inch full HD about 82 (calculated from resolution and screen size). WQHD or above if you want room to lay out spreadsheets and documents side by side, 4K if you want small text sharp, and 23.8-inch full HD if your desk is shallow and you want to keep the price down.

How many watts of USB-C charging do I need?

Check the wattage of your laptop’s charger and choose a monitor that delivers as much or more. Among the five, the BenQ GW2486TC, Dell S2725QC and I-O DATA LCD-CQ270SA-FX deliver 65 W, the EIZO EV2490 70 W and the I-O DATA LCD-CU273AS-FX 90 W. Whether charging works also depends on the laptop, so check the maker’s compatibility information too.

Which has the widest height range?

The EIZO EV2490, at 191.2 mm. The I-O DATA LCD-CU273AS-FX and LCD-CQ270SA-FX follow at 150 mm, then the BenQ GW2486TC and Dell S2725QC at 130 mm. All five turn to portrait.

Which gives me wired LAN over the same single cable?

Among the five, only the EIZO EV2490: a laptop connected over USB Type-C can use its LAN port. The runner-up I-O DATA LCD-CQ271SA-FX also has a wired LAN port, but its LAN works only with Windows 10 and 11.

Which has the longest warranty?

The EIZO EV2490 and I-O DATA’s LCD-CU273AS-FX and LCD-CQ270SA-FX, at five years (each within 30,000 hours of use). The Dell S2725QC has a three-year limited warranty, and the BenQ GW2486TC three years with one year on the panel and backlight.
