The DPVR E3 4K is a PC-tethered virtual reality head-mounted display developed by DPVR. Released in 2019, the E3 4K has a single 4K display with 3840 x 2160 pixels, which DPVR markets as "razor-sharp", and the company presents it for gaming and entertainment as well as group use in business and enterprise settings such as education, training and simulation.[1][2] The headset is part of DPVR's E3 series of PC-tethered headsets, which DPVR describes as tough hardware designed for heavy-duty use in business environments, with support for broadcasting content to multiple headsets.[2]

DPVR launched the E3 4K in Shanghai on 8 July 2019, with pre-sales in China at 2,999 yuan for the headset alone and 3,888 yuan for a bundle with the NOLO CV1 tracking kit.[3][4] On its own the headset tracks head rotation only, with three degrees of freedom; the NOLO bundle, sold outside China as the E3 4K Gaming Combo, adds positional tracking and two motion controllers.[2][5] As of October 2026, DPVR's English-language online store lists the E3 4K as out of stock.[1]

About review dates.

History and development

DPVR enterprise focus

DPVR (DeePoon VR) has focused on enterprise VR solutions. The company says its headsets are used around the world by leading brands across school education, training, simulation and enterprise sectors.[2]

E3 series

The E3 4K is part of DPVR's E3 series of PC-tethered headsets, offering various resolution and tracking options for different use cases.[2] The series began with the original E3, which DPVR (then also known as Deepoon VR) launched in Beijing on 28 March 2017 with a 2560 x 1440 Samsung AMOLED screen and an optional Polaris laser positioning system.[6] Unlike that model, the E3 4K uses a 4K LCD panel, and its bundled version uses NOLO CV1 tracking rather than Polaris.[3][4]

Announcement and release

China

DPVR presented the E3 4K in Shanghai on 8 July 2019. A DPVR press release published by Nweon called it the first product of the company's "4K strategy" and named the bundle the E3 "Game Warrior" Bundle 4K Edition (E3游戏战神套装4K版). Pre-sales opened the same day at DPVR's flagship stores on JD.com and Tmall. The bundle had a launch price of 3,888 yuan, and the headset alone was priced at 2,999 yuan.[3] PConline also reported the 3,888 yuan pre-sale price on JD.com and said the bundle carried over the NOLO CV1 positioning system from DPVR's earlier NOLO CV1 bundle.[4]

Japan

The Tokyo distributor Aiuto released the E3-4K Gaming Combo in Japan on 20 December 2019, at an expected street price of 59,800 yen including tax. The package combined the headset with a NOLO CV1 kit made up of two controllers, a marker that attaches to the headset, and a base station.[5]

United States and Europe

In September 2019 the gaming site KeenGamer reviewed the E3 4K Gaming Combo and said it could be bought by contacting DPVR directly.[7] DPVR's E3 range page gives a price of US$378 for the E3 4K.[2] DPVR's English-language store lists it at US$378.00 to US$388.00 in hard-strap and soft-strap versions (SKUs 07-000181 and 07-000182) and marks it out of stock; an archived copy of DPVR's European store from October 2024 showed a range of 378 to 388 euros.[1][8]

Design and hardware

DPVR's user manual for the headset (model E3-4K) lists the following accessories in the box: a user manual, warranty guide, certificate of quality and a back foam cushion.[9] DPVR's specification sheet lists "PC" as the headset's processor and gives it no battery, so the connected computer does the processing.[10]

Display system

The E3 4K features a high-resolution JDI display. PConline described it as a Japanese-made JDI Fast-LCD panel with a hardware resolution of 3840 x 2160 and a refresh rate of 75 Hz.[4] The DPVR press release gave the screen size as 5.5 inches and the pixel density as 818 pixels per inch (PPI).[3] DPVR's manual describes the screen as "Fast-LCD designed for VR" with a resolution of "3840x2160 RGB".[9]

  • Resolution: 3840 x 2160 total[9]
  • Screen Size: 5.5 inches[3]
  • Display Type: JDI Fast LCD[4]
  • Pixel Density: 818 PPI[3]
  • Refresh rate: 75 Hz in 2019 launch materials; 90 Hz in DPVR's May 2022 specification sheet[4][10]

KeenGamer gave the per-eye resolution as 1920 x 1080 in its review, while also giving the combined figure as 3840 x 2160.[7]

Optical system

  • Lens Type: Fresnel lenses[1]
  • Design: DPVR says the lens design reduces stray light and halo effects[2]
  • IPD Range: 54-74 mm, described by DPVR as "adaptive"; the headset supports wearing glasses[9]
  • Field of view: 110°[9][10]

KeenGamer described the lenses as having a fixed interpupillary distance, while DPVR describes its 54-74 mm range as adaptive.[7] Aiuto's Japanese release listed a 100° field of view, while DPVR's manual and specification sheet list 110°.[5][9][10]

Comfort

  • Head Strap: According to the manual, the strap adjusts itself to head size through a built-in resilient structure. Users with large heads can remove the back foam cushion, and users with small heads can attach it if the headset slips.[9]
  • Face Interface: A replaceable face foam cushion attached with hook-and-loop fastener.[9] KeenGamer noted that the cushion looks like leather but is foam, and that it is not flexible and may let light in on narrower faces.[7]
  • Weight: 300 g without head straps and cables, according to DPVR; KeenGamer listed 295 g.[9][7]

The manual lists the headset's dimensions as 266 mm x 194.5 mm x 96 mm; Aiuto's release gave 265 x 195 x 130 mm.[9][5]

Sensors, connections and audio

DPVR lists a gravity sensor, compass and gyroscope; Aiuto described the same set as a gyroscope, accelerometer and magnetometer.[9][5] A single 3-in-1 cable ends in one HDMI 1.4b connector and two USB 2.0 connectors, and a separate 3.5 mm audio cable carries sound to headphones.[9] The manual says that if the screen stays black, the headset's USB power lead should be connected to a 5 V, 2 A power adapter, because some motherboards cannot supply 10 W over USB.[9] The headset has no built-in speakers, and KeenGamer noted that headphones are needed.[7][10] DPVR's specification sheet lists a built-in microphone.[10]

Tracking options

Standard mode

3DoF (three degrees of freedom) head tracking. DPVR lists the E3 4K as a 3DoF headset.[2][10] The manual recommends using the headset seated.[9]

6DoF upgrade

Compatible with the NOLO VR tracking system. DPVR says its E3 GC models include NOLO positional tracking that brings "room scale" tracking and motion controls to the headset.[2] In the Gaming Combo, a NOLO marker attached to the headset and two NOLO controllers are tracked from one base station.[5]

  • Room-scale positional tracking[2]
  • Motion controllers[5]
  • Position accuracy: less than 2 mm (figure given in NOLO's 2017 Kickstarter campaign)[11]
  • Latency: less than 20 ms (positioning delay given in the same campaign)[11]

The campaign said one base station could track movement within a 13 x 13 feet (4 x 4 meters) space.[11] In its review, KeenGamer found the NOLO tracking "not as precise as we hoped", reported lag, jitter and misalignment during fast movement, and recommended the standing-only mode.[7]

Software compatibility

Platforms

DPVR's PC software, DPVR Assistant, installs the headset drivers, checks the headset connection and handles firmware updates.[9][5] DPVR's support site lists the E3 4K among the headsets supported by its 3DoF PC-VR Assistant for 64-bit Windows 7, 8, 10 and 11.[12] At the Chinese launch, DPVR named Beat Saber, Skyrim VR and Fallout 4 VR among the compatible PC games, and listed Blu-ray film playback without login, more than 30,000 3D and 360-degree videos, sports broadcasts on a virtual 800-inch screen, local video playback and a virtual desktop.[3][4]

Enterprise features

  • Broadcasting content to multiple headsets: DPVR says an E3 can work as a wired broadcast system that takes content from a single HDMI source and shares it with many headsets, for training rooms or classrooms[2]
  • Group training and presentations[2]
  • Hardware customization and OEM supply[2]
  • Designed for heavy-duty business use[2]

DPVR's 2022 specification sheet lists screen mirroring and DPVR's Group Training System as supported on the E3 4K, but not its Starlink system.[10]

System requirements

DPVR's manual gives separate recommended PC specifications for games and for 3D and 360-degree video.[9]

E3 series variants

DPVR offers multiple E3 models. Its 2018 English website listed the E3-B, E3-C and E3-P, and its current store describes three models: the E3 C, the E3 4K and the E3 4K Gaming combo.[1][13]

  • E3B: Model with a Samsung 5.7-inch AMOLED panel (2560 x 1440), listed on DPVR's website in 2018[13]
  • E3C: Entry-level model with a 2560 x 1440 panel, US$258 on DPVR's range page[2]

Reception

KeenGamer's Hrvoje Smoljic gave the E3 4K Gaming Combo a score of 7.5 out of 10 in September 2019. He called the display the headset's main strength, writing that the higher resolution made the image "noticeably sharper and more detailed", and said its 75 Hz refresh rate was only slightly lower than those of competing headsets. He found the headset light, at about half the weight of the Oculus Rift, and the DPVR Assistant software easy to use. His criticisms were the inflexible face cushion, which did not suit every face shape, the laggy NOLO tracking and the number of cables, since the main cable ends in an HDMI plug and three USB plugs. He described the combo as one of the cheapest PC-tethered devices and called it worthwhile for newcomers to VR.[7]

Status

As of October 2026, DPVR's English-language store lists the E3 4K as out of stock, and the PC-tethered 3DoF section of DPVR's product menu lists the E4C and E3S.[1] When DPVR announced the DPVR E4C arcade headset on 19 October 2023, vice president Derek Liu said it was built on the E3 series, which he said had served for seven years and captured 90% of the market.[14]
