The HP E14 G4 is the right 14-inch portable monitor for one specific buyer: someone whose laptop, tablet or handheld already sends video over USB-C and who wants the lightest 1080p panel they can carry. Everyone else should read our guide to USB-C portable monitor compatibility before ordering, because the E14 G4 has no HDMI input, no USB-A video path and no fallback of any kind.
Inside the 640 g frame sits a 14-inch IPS panel at 1920 × 1080 and 60 Hz, rated at 400 cd/m² with an anti-glare coating and driven by two USB-C ports that both carry DisplayPort 1.2 Alt Mode. The second port accepts a wall charger and passes up to 65 W back to the laptop, so the same cable that lights the screen can also top up the host.
Power draw is the quiet advantage. HP rates the E14 G4 at 3.5 W typical and 6 W maximum, against the 7 W to 15 W that most 15.6-inch portables pull. That gap is why a laptop can drive this monitor for a full working session without the battery complaint that follows most bus-powered second screens.

Quick verdict. The E14 G4 remains a credible travel monitor six years after launch, but only for USB-C video hosts. If your port carries DisplayPort Alt Mode or Thunderbolt, it delivers the best mix of weight, rated brightness and power efficiency in the 14-inch class. If you need HDMI, audio, VESA mounting or verified colour accuracy, your money belongs on a different panel.
HP E14 G4: Overview
HP announced the E14 G4 in May 2020 and shipped it that September as a business travel display for its corporate laptop line. HP still lists it in its 2026 portable monitor catalogue under the model family 1B065A8 and 1B065AA, with 1B065AA#AC3 as the U.S. retail reference and 1B065AA#ABB covering UK and European packaging. HP has published no end-of-production notice, so the accurate description is a 2020 design still sold new, not a current launch.
The G4 label misleads. HP's documented portable line runs from the EliteDisplay S140u, to the EliteDisplay S14, to this monitor, to the Series 5 Pro 514pn. There is no documented E14 G1, G2 or G3 portable monitor, and nothing in HP's catalogue suggests this chassis had three earlier iterations.
The step up from the S14 is real, though. Claimed brightness doubled from the 200 to 220 cd/m² class to 400 cd/m², weight fell from roughly 1 kg to 640 g, a second USB-C port arrived with 65 W pass-through, and the wraparound easel cover was split into a fixed 0° to 78° kickstand plus a separate sleeve. The S140u belongs to a different architecture entirely, since it carried video over USB 3.0 graphics rather than DisplayPort Alt Mode, which is why nothing about that older monitor tells you whether this one will work with your laptop.
Specs & What's in the Box
Retail configurations ship with the monitor, one USB Type-C cable, a soft protective sleeve, a Quick Setup Poster and documentation. The included cable is short, and owners describe it as too short to place the monitor on the far side of a laptop, so a longer full-featured cable is the first thing worth adding for anyone who works across a wide desk.
HP lists the monitor at 321.4 × 15.2 × 210 mm with the stand. The widely repeated "less than 4.75 mm" figure applies to the thinnest section of the profile, not the total depth, which is 15.2 mm once the panel housing and folded kickstand are included. Weight lands at 640 g, or 1.41 lb, and the active image area measures 309.31 × 173.99 mm.
The on-screen menu covers brightness, contrast and image controls, colour, input selection, power management and the low-blue-light mode, with 10 user-programmable settings recorded in HP's QuickSpecs. The U.S. warranty is a standard three-year limited hardware warranty; regional service bundles differ.
Connectivity: Which Hosts Actually Work
Both USB-C ports carry DisplayPort 1.2 Alt Mode, and neither is a general-purpose USB port. HP's requirement for one-cable operation is explicit: the host must supply 5 V at 3 A and output video over DisplayPort Alt Mode or Thunderbolt 3. A USB-C port that handles data and charging only will never produce a picture, no matter which cable you attach.
The two-port layout is what makes charging work while docked. A USB-C power adapter goes into one port, the host cable into the other, and the monitor negotiates up to 65 W back to the laptop after the panel takes its own share of the incoming power.
| Source device | Works over USB-C | Why |
|---|---|---|
| Windows laptop with DP Alt Mode or Thunderbolt | Yes | Meets the 5 V/3 A plus DisplayPort requirement |
| Mac with USB-C or Thunderbolt | Yes | Standard external display behaviour over the same video path |
| USB-C iPad | Yes | Supported iPad models output DisplayPort over USB-C |
| Steam Deck or ROG Ally | Yes | Both expose DisplayPort 1.4 Alt Mode on their USB-C port |
| USB-C phone | Sometimes | The phone must output DisplayPort video and supply enough current |
| PS5, Xbox, Switch dock, HDMI-only laptop | No | The monitor has no HDMI, mini-HDMI or DisplayPort socket |
| Laptop or desktop with USB-A only | No | USB-A carries no DisplayPort Alt Mode |
| Dock or hub downstream USB-C port | Usually no | Many downstream sockets are data or charging only |
The hardest case is an HDMI source. A passive USB-C-to-HDMI cable is built to run from a USB-C source to an HDMI display, and reversing that direction does not work. Feeding a PS5, an HDMI-only laptop or a camera into the E14 G4 requires an active HDMI-to-USB-C converter plus separate power for the monitor, a chain that is adapter-specific rather than a supported configuration. Our portable monitor no-signal fix guide walks through the same cable-level diagnosis for both paths.
Build Quality & Durability
At 640 g and 15.2 mm at its thickest point, the E14 G4 is built around movement. The kickstand is permanently attached and tilts from 0° to 78°, which covers lap, tray-table and hotel-desk use, but there is no height adjustment, no swivel and no pivot, so the built-in stand does not convert to portrait orientation.
The panel carries a 3H anti-glare coating with 24% haze, a level of diffusion that keeps ceiling lights and window glare from washing out the image. HP's datasheet does not identify the chassis material, so treat material claims that go beyond the datasheet as unconfirmed.
Protection is thin by design. The bundled sleeve guards against scratches and dust, carries no documented impact rating and does not double as a stand. For air travel or a packed bag, a padded or semi-hard case is the practical addition, particularly because the folded kickstand adds depth to the monitor's packed profile.
Performance: Brightness, Colour and Power
Brightness is where the E14 G4 still leads its class on paper. HP rates the panel at 400 cd/m², a full 100 cd/m² above the 300 cd/m² typical of the Dell P1424H and the Lenovo ThinkVision M14, and well clear of the 250 cd/m² of 15.6-inch models such as the ViewSonic VG1655 and the ASUS ZenScreen MB16ACV. Paired with the anti-glare coating, that rating is the reason the monitor stays readable near a window; no panel in this category is sunlight-readable, whatever the marketing says.
Contrast is the weak point. HP specifies 800:1 typical static contrast and 600:1 minimum on an IPS panel, a modest figure next to the 2000:1 that IPS Black and OLED panels now claim. Blacks will read grey in a dark room, and the 5,000,000:1 dynamic figure is a backlight-modulation number rather than a static measurement.
Colour is a business specification, not a creative one. HP publishes 72% NTSC and nothing else: no sRGB, Adobe RGB or DCI-P3 percentage, and NTSC coverage is not interchangeable with those standards. Photo and video work that depends on verified gamut and calibration belongs on a different display.
Refresh is 60 Hz with a 5 ms grey-to-grey response using overdrive. That is comfortable for documents, code, dashboards and spreadsheets, and it is not a gaming specification. There is no adaptive sync and no high-refresh mode.
Power is the standout. At 3.5 W typical and 6 W maximum, the E14 G4 draws less than the 15.6-inch portables that commonly run between 7 W and 15 W. A laptop driving it over one cable sees a far smaller battery penalty, and a power bank with enough output to clear the 5 V/3 A startup requirement can run the panel standalone while the second port carries video.
Flicker-free backlight control and a TÜV-certified low-blue-light mode round out the eye-care features, and HP documents an auto-sleep behaviour that wakes when the host restores the video signal. Whether the 400 cd/m² rating holds up in practice is harder to establish: HP's figure is a specification, and the panel is the same 1080p IPS class that has been in this segment since 2018.

Against the Dell P1424H and the Lenovo ThinkVision M14t Gen 2, the E14 G4 splits on two numbers: 400 cd/m² instead of 300, and 3.5 W typical draw against 5 W and 6 W. Everything else is close. All three are 14-inch 1080p 60 Hz business panels with two USB-C DisplayPort inputs, up to 65 W pass-through, no HDMI, no speakers and no touch. Buyers who want the broadest service network or the newest chassis have grounds to choose Dell or Lenovo; buyers who carry the screen every working day get a lighter, brighter, more efficient panel from HP.
Against the ViewSonic VG1655, the trade is size and connectivity for weight. The ViewSonic is a dimmer 15.6-inch panel at 250 cd/m² and 820 g, but it adds a mini-HDMI input, a 3.5 mm audio output and stereo speakers, and it ships with an HDMI-to-mini-HDMI cable and an AC adapter. For a PS5, an HDMI camera or a desktop tower, that single port removes the converter chain the HP requires.
The ASUS ZenScreen MB16ACV takes a different route to the same problem: one USB-C DisplayPort input plus a DisplayLink-based USB-A path that works on older PCs with the right driver, something the E14 G4 cannot do at all. It also adds a 1/4-inch tripod socket. At 900 g and a rated 250 cd/m², it loses the portability argument in exchange.
The most relevant comparison is internal to HP. The Series 5 Pro 514pn moves to a 14.36-inch 16:10 panel at 2560 × 1600 and up to 75 Hz, an IPS Black backlight rated at 2000:1 contrast, manufacturer claims of 100% Display P3 and 100% Adobe RGB coverage, the same dual USB-C with 65 W pass-through, a stand that works in portrait and a magnetic hard cover. It keeps the USB-C-only philosophy, so the compatibility rules do not change, but it addresses every panel limitation the E14 G4 still carries.

Who Should Buy the HP E14 G4?
Buy it if your laptop, Mac, USB-C iPad or handheld outputs DisplayPort video over USB-C; if you want the lowest weight in the 14-inch class at 640 g; if you work from hotel desks and trains where a 400 cd/m² anti-glare panel earns its rating; if you want the smallest battery penalty a second screen can impose; or if a three-year HP limited warranty matters for a company purchase.
Skip it if your source device is a PS5, Xbox or Switch dock; if your laptop offers only USB-A or HDMI output; if you need audio output or built-in speakers; if you want 120 Hz or higher for gaming; if you need VESA mounting or portrait orientation from the stand; or if you need verified gamut and accuracy for photo and video editing.
For handheld gaming the calculus improves. The Steam Deck and the ROG Ally both expose DisplayPort over USB-C, so the E14 G4 connects directly, and its 3.5 W draw limits how much it steals from the handheld's battery. Docks remain the weak link, since many route their downstream USB-C ports as data or charging only, which is the caveat our roundup of portable monitors for Switch and Steam Deck covers in detail.
Frequently Asked Questions
Q: Will the HP E14 G4 work with a MacBook or an iPad?
Yes, provided the USB-C or Thunderbolt port on the device carries display output. Macs treat it as a standard external display, and supported USB-C iPads output DisplayPort to external screens. The monitor can also pass charger power through to the tablet or laptop on one port while the other carries video.
Q: Can I run it from a power bank instead of a wall charger?
Yes, if the bank comfortably exceeds the monitor's 5 V/3 A startup requirement and video arrives through the other USB-C port. A high-output PD bank such as the Anker 737 qualifies on the electrical side. A power bank cannot create a video signal, so the host port still has to support DisplayPort Alt Mode.
Q: Why does my laptop charge slowly when it runs through the monitor?
Pass-through moves power from the charger to the laptop through the monitor, and the panel consumes its own share first. The ceiling is 65 W to the host when a suitable USB-C PD supply feeds the second port, so a laptop that expects more than that will still lose charge under heavy load.
Q: Can a USB-C dock or hub drive the E14 G4?
Only if the dock's downstream USB-C port is explicitly a DisplayPort Alt Mode output. Many hubs expose USB-C sockets that carry data and charging only, and the monitor will draw power from those ports without ever showing an image. HP's own USB-C Travel Hub G3 supplies HDMI 2.0 for an external display, but HP does not document a video-capable USB-C output for this monitor, so connect the E14 G4 directly to the laptop and route other peripherals through the hub.
Q: Is the supplied USB-C cable good enough?
It is the cable HP supplies for the one-cable USB-C setup, and it is short. Owners routinely describe it as too short to place the monitor on the far side of a laptop, so a longer replacement is the practical purchase. Any substitute must explicitly support DisplayPort video and USB Power Delivery; a charge-only USB-C cable will power the monitor without ever lighting the panel.
Conclusion & Final Verdict
The HP E14 G4 is a 2020 business monitor that has aged well in the ways a travel display must: 640 g, 15.2 mm at its thickest point, 3.5 W typical draw, a panel rated at 400 cd/m² with an anti-glare coating, and 65 W of pass-through charging, all over two USB-C ports. Six years on, nothing in the 14-inch class beats that combination of weight, rated brightness and power efficiency.
Its limits are just as clear. Video arrives over USB-C or not at all, contrast sits at 800:1 on an IPS panel, 72% NTSC is a business gamut with no published sRGB or DCI-P3 figure, and there is no HDMI, audio, touch, VESA pattern or high-refresh mode. Buyers whose sources are consoles, HDMI laptops or USB-A-only machines should choose a panel with mini-HDMI; buyers chasing sharper text, wider colour or portrait use should look at the HP Series 5 Pro 14 or the Dell P1424H.
For USB-C video hosts, it stays one of the most efficient second screens you can carry, and the only real setup risk is a cable that carries power but not video. Buyers who want a brighter, lighter take on the same format can also compare it with our picks for slim and lightweight portable monitors and the wider best portable external monitors for laptops.
