Handheld docks and TV output explained: USB-C, DisplayPort and HDMI

A dock only helps if the handheld itself states video output. Retroid, AYN, AYANEO and Anbernic each name it for specific models, from 1080p over USB-C to 4Kp60 DisplayPort, while several pages say only "HD connection to TV". This guide sets out what each maker states and what stays unstated.

A handheld reaches a TV in one of three ways: a USB-C port that carries a DisplayPort video signal, a dedicated HDMI-style output, or a maker's dock that takes the handheld's port and gives you an HDMI socket. Which one a device has is a maker decision, and the wording on product pages is inconsistent. Dock prices below are the maker's own listing, with no conversion.

How does a handheld send video over USB-C?

Some USB-C ports carry more than data and power: they can carry a video signal too. AYN's Odin 3 page labels this "DisplayPort 4Kp60 Alt Mode". AYANEO's Pocket S lists a USB 3.2 Gen 2 Type-C port that "Supports DP 1.4 video output" at up to 10Gbps, and 10Gbps is one of the three USB 3.2 rates that usb.org names (20Gbps, 10Gbps and 5Gbps). Retroid says the Pocket 5 outputs 1080p over USB-C (DisplayPort), and Anbernic states that the RG556's Type-C port supports 1080p DisplayPort output.

The USB-IF pages cited here do not define DisplayPort Alt Mode, so the term comes from the makers. USB-IF's USB4 page notes only that the Type-C connector "has evolved into the role as the external display port of many host products". The practical reading is narrow: a USB-C port is not guaranteed to output video, so the product page needs to say so.

What video output do makers state?

Anbernic's RG35XX SP page lists "HD connection to TV" under "Other function" and nothing about the socket, so a buyer cannot tell from that page which cable it needs. The Retroid Pocket 6 and Classic pages do not state any video output in their page text, so we make no claim for them. The figures for the Odin 3, Pocket 5 and Pocket 4 Pro come from the maker listings recorded for those devices, some in spec images.

What do the docks list?

Three makers sell a dock we can source. They differ in how much detail the page gives.

Retroid's dock page says the HDMI output is "up to 4K@60" without naming an HDMI version, and lists PD charging with no wattage, so the page does not tell you how much power it passes to the handheld. It also lists a Pocket 4 as having no HDMI support through the dock, which is a reminder that a dock's HDMI depends on the handheld's port as well. AYN's Super Dock page lists only the Odin 2 family, so the page gives no basis for using it with the Odin 3, which is a different model.

Two stated figures can apply at once. Retroid's dock lists HDMI up to 4K@60, while its Pocket 5 page lists 1080p over USB-C. The dock page does not say which figure governs the picture, so treat the lower, handheld-side figure as the one the maker commits to.

What does a stated resolution mean on a TV?

A resolution figure is a count of pixels, and the counts differ a lot. 1080p is 1920 x 1080, or 2,073,600 pixels. 4K, at 3840 x 2160, is 8,294,400, four times as many. So a maker that states 4Kp60 for the Odin 3 and one that states 1080p for the Pocket 5 are describing signals of very different size, and the "p60" part is the refresh rate in frames per second. The gap matters in one direction only: a 1080p source on a 4K television is scaled up by the TV, and nothing on the maker pages says how that looks.

The two-figure problem from the dock section repeats here. A dock's HDMI figure is a ceiling that depends on the handheld feeding it. Retroid's dock lists HDMI up to 4K@60, but the Pocket 5 states 1080p over USB-C, so a 4K television connected through that pairing is still fed from a handheld that states 1080p. The Odin 3 states 4Kp60 and the Anbernic RG556 states 1080p, so the two handhelds state different ceilings for the same television.

What do the Retroid dock cautions say?

Retroid's dock page has more compatibility detail than the other dock pages cited here, and it is worth reading line by line. It rates the Retroid Pocket models like this: RP Nova, RP6, RP5 and RP4 Pro "fully compatible", RP4 "partial compatible (no HDMI support)", RP3+ "partial compatible", RP3 "charge only", RPMINI "not compatible" and RP2, 2S and 2+ "not applicable". For the RP3+, the page adds that the two USB 3.0 ports drop to USB 2.0 speeds, and warns against applying external power if you want the four USB ports or the network port to work while the RP3+ runs on battery. With external power connected, those ports stop working and the dock only charges the handheld.

The lesson is wider than one dock: a compatibility list can hide several different outcomes, from full to charge-only, so read the exact word next to your model. The store page also shows "Sold out" beside an "Add to cart" button, so availability is unclear.

Which dock suits which handheld?

Reasoning only from the stated lists, the pairings look like this.

• Retroid Pocket 5, 6 or 4 Pro: the Retroid Official Dock lists all three as fully compatible. The Pocket 6 page itself states no video output in its page text, so the dock page is the only maker statement of TV use for that model.
• AYN Odin2 Portal: AYN lists the Super Dock as fully compatible and the Portal states DisplayPort 4Kp60, but the dock page lists no ports and no output, so what the dock outputs is not stated.
• AYN Odin 3: the handheld states DisplayPort 4Kp60 Alt Mode, but the Super Dock page does not name it, so neither maker supports that pairing in writing.
• Analogue Pocket: the Analogue Dock is the intended route, with 1080p HDMI and two USB inputs; Analogue states no dock price on its page.
• Miyoo Flip V2: the maker lists HDMI output, so the socket may need only a cable, but the page does not name the connector type.

On price, the figures are not comparable. AYN states USD for the Super Dock at $48.00, while Retroid shows $29.90 without naming a currency, and the two docks list very different amounts of detail. The listed difference is $18.10 on paper, but it should not be read as a like-for-like saving.

Do you need a dock, or will a cable do?

If your handheld states video over USB-C, a cable or adapter may be enough, and the maker's wording is the guide. Retroid sells a 1.5M Micro HDMI to HDMI cable that it says can stream audio and video from the Retroid Pocket to a TV or projector with an HDMI port, listed at $10.00 (checked Oct 2026) and shown sold out. That cable is for handhelds with a micro HDMI socket, so match it to your device's listing. The Pocket 4 Pro states both Type-C and HDMI 720P output.

A dock adds charging while you play, a wired network port on Retroid's dock, and extra USB ports for controllers. Whether a handheld works as a console on a TV is also about the software: see Android vs Linux retro handhelds for how the two families differ on controller and display handling.

What should you check before buying a dock?

1. Does the handheld's own maker page state video output over USB-C, and at what resolution?
2. Does the dock page list your exact model as compatible, not just the brand?
3. Does it state an HDMI version or resolution, and a PD charging wattage?
4. Is the cable length and connector type stated, if you are buying a cable instead?
5. Is it in stock? Every dock and cable above showed as sold out, out of stock or backordered when checked, though the two Retroid pages also showed an add to cart button.
6. Does the compatibility list say "fully", "partial" or "charge only" for your model? Retroid uses all three, and the difference decides whether HDMI works.
7. Are there power-supply cautions? Retroid's RP3+ note says external power can disable the USB and network ports.
