For playing most retro games or using a vintage computer interactively, choose an LCD. E-paper refreshes too slowly for most images that change constantly. Its better fit is a static display, persistent status panel, or a game deliberately designed around slow updates. The refresh figures below apply to specific products and modes; they are not universal specifications for either display type.
Why LCD is the practical choice for most retro games
Games with moving sprites, scrolling backgrounds, animation, or rapidly changing text need a screen that can update repeatedly as the action unfolds. The e-paper examples covered here take hundreds of milliseconds or several seconds to refresh, depending on the product and refresh mode. Their manufacturers explicitly caution against frequent screen updates. That makes them a poor match for most continuously moving game images.
LCD is therefore the practical default when the screen must keep pace with an interactive game or computer session. That is a conclusion drawn from the manufacturers’ published refresh guidance, not from a controlled comparison or a hands-on test. The available information does not establish comparative input latency, response times, or frame rates for particular LCD and e-paper models.

In that case, e-paper’s reflective display and low power use while the image is unchanged may be useful. The important question is not simply whether a screen can show a computer’s output: it is whether it can update at the pace your software requires.

How the display types differ in actual use
Refresh behavior matters more than a general label
“E-ink” is often used casually to refer to e-paper displays. The published examples here show why you should check the exact model and mode rather than assume one refresh speed applies to all e-paper. DFRobot specifies a full refresh of 3 seconds and a partial refresh of 680 milliseconds for its DFR0591 2.13-inch module. Those are product specifications for that module, not a promise of a gaming frame rate.
Pimoroni lists core refresh times of 12 seconds for its 4.0- and 13.3-inch Inky Impression Spectra 6 displays and 28 seconds for its 7.3-inch version. Its product information also says a complete refresh in real-world use can take 20–35 seconds depending on the Raspberry Pi’s speed and the panel. The core and real-world figures describe different conditions; neither should be read as a universal e-paper refresh time.
Those refresh intervals are far slower than the repeated updates expected by most action games. A partial-refresh figure may sound shorter, but DFRobot still advises against frequent-refresh applications for its DFR0591. Do not infer that partial refresh makes a particular e-paper panel suitable for games without checking the model’s own guidance and testing the intended software.
Refresh is also a workflow issue, not just a number on a specification sheet. A screen that takes 680 milliseconds for one partial update may still feel unresponsive when a game needs many updates in succession. A full refresh can interrupt a turn-based interface with a visible pause, while a 20–35-second real-world cycle would dominate any interactive session. Conversely, a screen that changes only when a user selects a new piece of artwork can make those same delays irrelevant. Define the longest acceptable pause for your project before comparing panels.
Static images are where e-paper has a clearer advantage
Pimoroni describes its e-paper displays as reflective, visible under bright light, and free of an LCD-style backlight. It says the display consumes power only while refreshing. DFRobot says the DFR0591 retains its last image when powered off. These are manufacturer-stated product traits, relevant to projects where a picture or status display can remain unchanged for long periods.
That does not make e-paper a general-purpose substitute for an interactive monitor. Its strength is showing an image that does not need constant updates: for example, a fixed piece of pixel art or a status screen that changes only occasionally. No medical claim about eye health follows from these display characteristics, and the cited product information does not establish one.
Those traits can simplify a display that must remain visible while the host is asleep or switched off, because the DFRobot module is documented as retaining its last image. They do not eliminate the need to power the host, drive the SPI interface, or perform a refresh when new content is required. Treat “power only while refreshing” as a product-use description, not as a measured whole-system energy figure.

Color, brightness, and size depend on the specific product
The named e-paper and LCD examples do not provide a complete, like-for-like picture-quality comparison. For example, Raspberry Pi lists its 15.6-inch Monitor as a Full HD IPS LCD with 16.2 million colors and typical brightness of 250 nits. Pimoroni’s named Inky Impression variants are color e-paper, but the supplied product details do not establish a directly comparable color count or brightness figure for them.

For a vintage computer, the source and display also have to agree on a usable connection path. Raspberry Pi’s monitor page lists HDMI input. DFRobot’s module is an SPI e-paper module with published Raspberry Pi compatibility limits. The available specifications do not establish that a particular vintage computer, emulator, adapter, or scaling setup works with any of these products. Check the exact output, display input or interface, and any required conversion hardware before buying.
Size changes the practical experience as much as the panel technology. The DFRobot example is only 2.13 inches, whereas the Inky Impression family includes 4.0-, 7.3-, and 13.3-inch versions, and the Raspberry Pi Monitor is 15.6 inches. A small e-paper module may be excellent for a compact status badge but unsuitable as the only screen for a shared arcade cabinet. The listed sizes are not a recommendation to substitute one product for another; they simply show why the intended viewing distance and enclosure must be part of the specification.
What the named product specifications do—and do not—show

The table is a comparison of the specifications reported for these examples, not a controlled test. The sources do not establish a common test method for refresh, image quality, power consumption, or compatibility. A blank comparison in the available information is not evidence that two products perform alike.

The Raspberry Pi Monitor’s 1920 × 1080 resolution and 16.2 million colors describe that LCD model. They do not prove that every emulator will scale cleanly, nor that an older computer will output that timing without an adapter. Likewise, the absence of comparable figures for the e-paper products should not be interpreted as a performance ranking.
Choose a screen for the kind of project you are building
For arcade games and emulators
Use an LCD if the screen must display typical action, scrolling, or animated play. Raspberry Pi Press’s Retro Gaming with Raspberry Pi includes a 27-inch LCD monitor in an arcade-cabinet build. That is a documented build example, not a claim that every LCD size or cabinet layout is ideal. Choose a screen that fits the cabinet and can accept the signal path your gaming hardware provides.
For an arcade cabinet, also budget for the physical installation rather than comparing panel prices alone. The documented Raspberry Pi example uses a 27-inch LCD, while the Raspberry Pi Monitor specification describes a 15.6-inch unit with VESA and screw mounting. Those mounting provisions can matter when designing a frame, but they do not establish that either size fits your cabinet. Measure the opening, mounting points, viewing distance, and cable route before ordering.
The same guide warns that old-school arcade CRTs use high voltage and are extremely dangerous. If you are considering a CRT, treat it as a hazardous component rather than assuming it is a straightforward swap for an LCD. The cited guide’s warning is not a repair procedure; work involving CRT internals requires appropriate expertise and precautions.
For a vintage computer used interactively
An LCD is the safer starting point if you will type, navigate menus, or run software with changing screens. Before settling on a monitor, verify that your computer’s output can reach the monitor’s input. For the Raspberry Pi Monitor example, the listed video input is HDMI. The available sources do not provide a compatibility matrix for vintage computers or adapters, so they cannot confirm that a particular machine will connect directly or display correctly.

Do not assume that a display marketed for Raspberry Pi accepts a normal video signal. The DFRobot DFR0591 is an SPI peripheral, not an HDMI monitor. It requires a host and software path that can drive that interface, and DFRobot names systems it cannot support, including some newer Raspberry Pi systems and the Pi Zero 2 W. A vintage computer would need an appropriate intermediary arrangement; no such arrangement is documented by the cited specifications.
Consider e-paper only if your use is mostly static—for instance, a display project that presents a fixed image or a slow-changing status view. If the e-paper module is intended for a Raspberry Pi, confirm that the exact board and operating system are compatible with the module’s interface and driver. DFRobot specifically identifies systems it cannot support; compatibility should not be inferred from the phrase “for Raspberry Pi” in a product name.
For pixel art, status panels, or slow-update experiments
E-paper makes more sense when the project can tolerate a pause after each update and benefits from a reflective screen, a persistent image, or power use concentrated around refreshes. A game designed around turns or infrequent screen changes may be worth experimenting with, but the available specifications do not establish how any particular game will behave. Check the panel’s full- and partial-refresh guidance, then judge the result with the actual software and hardware you plan to use.
Recommended Free Tools
For the DFR0591, the 680-millisecond partial-refresh specification should not be treated as a guarantee that every partial update takes that long in every setup, or that motion will look smooth. The manufacturer’s warning against frequent updates still matters. For Inky Impression, the much longer stated refresh times make a continuously animated game an especially poor fit.
A sensible slow-update design can make the limitation part of the interface: a turn-based screen can refresh after a move, a museum label can change when a visitor selects an item, or a decorative pixel-art panel can remain unchanged for hours. In each case, calculate how often content really changes and whether a full refresh is acceptable. If the answer is “many times per second,” these e-paper examples are outside their documented use guidance.
Cost, availability, and mounting considerations
Price comparisons are necessarily time-sensitive. Raspberry Pi’s product page showed $100 for its 15.6-inch Monitor when accessed for the 2026 source snapshot. The DFRobot DFR0591 page showed the module out of stock at that time, so even a technically suitable design may require waiting or finding an alternative. The cited Pimoroni information identifies several Inky Impression sizes but does not establish a current price in the material summarized here. Check the manufacturer or authorized seller for your region, currency, stock, and any current revision before committing.
Include the complete display chain in your budget: the panel, host board, power supplies, cables, mounting hardware, and any signal conversion required by the computer. The Raspberry Pi Monitor lists HDMI input, USB-C power, speakers, and VESA/screw mounting, which may reduce the number of separate display accessories in a cabinet or desk setup. The DFRobot module’s SPI interface and driver requirements imply a different build approach; its low refresh power claim does not provide a total project cost or energy calculation.

- Identify the exact computer or host. Record the board or computer model and, where relevant, its operating system. Do not assume compatibility from a product family name.
- Identify the display’s input or interface. The Raspberry Pi Monitor lists HDMI input; the DFRobot DFR0591 is an SPI module. These are different connection approaches, so confirm that the host and any required hardware support the one the display needs.
- Check named compatibility exclusions. DFRobot says the DFR0591 cannot be driven on some newer Raspberry Pi systems or the Pi Zero 2 W. Its product information does not give a universal compatibility guarantee for every other setup either.
- Check the driver and software path. Confirm that the exact device, operating system, and intended application can use the required display driver. The cited sources do not provide a complete operating-system or vintage-computer compatibility matrix.
- Match the screen to update frequency. If software changes the image continuously, prefer LCD. If updates are rare, check the e-paper model’s specific full- and partial-refresh guidance and whether the project can tolerate waiting.
- Confirm physical fit and power. Compare the panel’s dimensions, mounting method, cable access, and power connectors with the enclosure. The Raspberry Pi Monitor lists USB-C power and VESA/screw mounting; those features still need to match your build.
- Confirm current stock and price. Manufacturer product pages can change. The DFRobot page showed the module out of stock in the 2026 source snapshot; Raspberry Pi’s page showed $100 for its monitor at that time. Neither figure establishes current regional availability or price.
What the specifications cannot tell you
The cited product pages give useful model-specific refresh and display details, but they do not report a controlled LCD-versus-e-paper comparison. They also do not establish a specific retro computer’s compatibility, an emulator’s frame rate, adapter behavior, scaling quality, or input latency. Do not turn the listed refresh intervals into comparative gaming benchmarks: the sources do not describe a shared test, and an e-paper refresh interval is not itself a measure of a complete gaming setup’s performance.
For the same reason, a monitor’s listed resolution, color count, and brightness are product specifications rather than proof that it will reproduce every old system’s output as intended. The connection chain and the needs of the software still matter. When those details are not documented for the exact combination, compatibility remains something to verify rather than assume.
Even a successful connection does not answer every usability question. The supplied product specifications do not report ghosting, viewing-angle measurements, emulator scaling results, controller-to-screen latency, or a shared power test. Those characteristics can matter to a particular build, but they require model-specific testing or documentation. Keep that distinction clear when reading a refresh number or a color specification.

Frequently asked questions
Can the DFRobot 2.13-inch e-paper module run a retro game?
It is not a practical choice for a conventional continuously animated game. DFRobot lists a 3-second full refresh and 680-millisecond partial refresh, and explicitly says the module is not recommended for applications requiring frequent refreshing. It could be used for a deliberately slow, turn-based, or mostly static experiment if the host and driver are compatible.
Is a partial refresh fast enough for scrolling?
No conclusion of smooth scrolling follows from the 680-millisecond figure. That timing is a specification for the DFR0591’s partial mode, not a frame-rate measurement, and the same manufacturer still discourages frequent updates. Test the exact software and panel if motion is central to the project.
Which Inky Impression size is best for gaming?
None of the listed variants is presented as a gaming monitor. Pimoroni lists 12-second core refresh for the 4.0- and 13.3-inch versions and 28 seconds for the 7.3-inch version, with complete real-world refreshes taking 20–35 seconds depending on the Pi and panel. Those products fit static artwork or slow-update displays better than action games.
Can I connect a vintage computer directly to the DFRobot module?
The cited specifications do not establish that. The DFRobot device is an SPI Raspberry Pi module, while a vintage computer’s video output and software would need a compatible interface and driver path. Check the exact computer, conversion hardware, operating system, and application rather than relying on the product name.
Does e-paper use no power when the image is static?
Pimoroni says its displays consume power only while refreshing, and DFRobot says the DFR0591 retains its last image when powered off. Those are useful product traits for static content, but they are not a measured whole-system energy result. The host and any interface electronics may still draw power.

Is the Raspberry Pi Monitor suitable for every retro system?
It offers a straightforward LCD specification—15.6-inch Full HD IPS, HDMI input, USB-C power, speakers, and VESA/screw mounting—but no cited source provides a compatibility matrix for every vintage computer or emulator. Verify the source signal, adapter or scaler, resolution behavior, and physical fit for your particular system.
Should I use a CRT instead for authenticity?
The Raspberry Pi Press arcade guide documents a 27-inch LCD cabinet build and warns that old-school arcade CRTs use high voltage and are extremely dangerous. A CRT is not a simple drop-in alternative if it involves internal service. Treat that warning seriously and use qualified expertise for hazardous work.
Bottom line for the two use cases
- Choose LCD for most retro gaming, emulation, and interactive vintage-computer use, where the image changes repeatedly.
- Consider e-paper for static artwork, persistent status information, or a project deliberately designed for slow updates.
- Use the exact model’s specifications: the DFR0591’s 3-second full and 680-millisecond partial refresh figures, and Inky Impression’s 12- to 28-second core figures, describe named products only.
- Verify the complete connection and compatibility path for the exact host, operating system, interface, driver, power arrangement, mounting method, and display before purchasing or building around a specific module.
- Check current price and stock at the time of purchase; the Raspberry Pi Monitor was listed at $100 and the DFRobot module was shown out of stock in the 2026 product-page snapshot.
Frequently Asked Questions
Can the DFRobot 2.13-inch e-paper module run a retro game?
It is not a practical choice for a conventional continuously animated game. DFRobot lists a 3-second full refresh and 680-millisecond partial refresh and says the module is not recommended for frequent-refresh applications. It may suit a deliberately slow or mostly static experiment if the host and driver are compatible.
Is a partial refresh fast enough for scrolling?
The 680-millisecond figure is a product specification, not a frame-rate or smooth-scrolling result. DFRobot still discourages frequent updates, so test the exact panel and software before relying on partial refresh for motion.
Can I connect a vintage computer directly to an e-paper Raspberry Pi module?
The cited specifications do not establish that. The DFRobot device uses SPI and requires a compatible host and driver path; verify the computer, conversion hardware, operating system, and application.
Does e-paper use no power when a static image is displayed?
Pimoroni says its displays consume power only while refreshing, and DFRobot says the DFR0591 retains its image when powered off. These are product traits, not a measured whole-system energy result; the host and interface may still draw power.
Is the Raspberry Pi Monitor compatible with every vintage computer?
It has HDMI input and useful LCD specifications, but no universal vintage-computer compatibility matrix is provided. Check the source signal, scaler or adapter, resolution behavior, and physical fit for your system.
