Roku Ultra Review: The Power-User Roku, Tested

Every Roku marketing page shows off the stick-form devices. The Ultra is the one they don't push nearly as hard, and it's built for a specific kind of frustrated customer: the one who's tired of buffering during the 8pm household rush and tired of losing the remote in the couch every single week.

It's a box, not a stick, and that trade buys you something real

Giving up the invisible-behind-the-TV form factor gets you a full-size USB-A port for local file playback, a microSD slot, and the feature that actually matters: a physical Ethernet port. Wi-Fi 6 helps on a congested network, sure, but plugging in a cable doesn't just help — it removes the variable entirely. If your stick-form Roku has ever dropped frames the moment three other people in the house got online, that's the exact problem a cable makes disappear.

The remote finder feature

Roku's remote finder is a small thing that turns out to matter a lot in daily use: press a button on the Ultra itself (or in the mobile app), and the remote emits a sound until you find it. It sounds minor until you've spent five minutes digging through couch cushions on a regular streaming device.

Interface and performance

Roku OS remains the calmest, least promotional interface among the major platforms: a straightforward grid of installed apps with minimal sponsored clutter. Navigation on the Ultra is noticeably snappier than on budget Roku sticks, largely thanks to more RAM and the wired networking option.

4K HDR playback is smooth, and Dolby Vision content looks correct on a compatible display. Where the Ultra doesn't lead the pack: it lacks AV1 decoding, a newer codec some competing Google TV boxes now support, though real-world content using AV1 is still limited enough that most people won't notice.

Where the extra cost doesn't pay off

If your only use case is browsing Netflix and YouTube on a stable home network, the Roku Streaming Stick 4K delivers essentially the same picture quality and app experience for meaningfully less money. The Ultra's advantages. Ethernet, the remote finder, local file playback via USB, are real but specific. If none of them apply to your setup, you're paying for hardware you won't use.

Who should actually buy this

The Ultra earns its price for two kinds of households: ones fighting a weak or crowded Wi-Fi signal who want the option to go wired, and ones that lose remotes often enough that the finder feature alone justifies the upgrade. Outside those two cases, put the difference toward the Streaming Stick 4K instead.

What the Ethernet port actually changes

The wired port is the clearest reason to choose the Ultra over a Roku stick, and it matters more than the processor difference for most people.

Streaming video needs a steady rate rather than a fast one, so the benefit of wiring isn't higher peak speed. It's the removal of variability. A Wi-Fi connection that averages plenty of bandwidth but dips for two seconds will stall playback; a wired one won't. Our guide to Ethernet versus Wi-Fi covers when that difference is worth acting on.

If your TV sits far from the router, or the household is busy in the evenings, this single port justifies the price gap on its own. If the router is in the same room and you've never seen buffering, it doesn't.

Roku's platform limits, whichever model you buy

A couple of constraints apply across the whole Roku lineup, and they're worth knowing before committing to the ecosystem:

• No VPN app support at any level. Covering a Roku with a VPN means configuring it on your router, covered in our guide to VPN routers.
• No Plex or Jellyfin server capability. Roku runs client apps for both but cannot host a library itself, unlike some Android TV hardware.

Neither matters for ordinary streaming. Both matter if you were planning around them.

Storage, and the error you'll eventually meet

The Ultra ships with more room than Roku's sticks, which delays rather than removes the storage problem that affects the platform generally. Install enough channels and you'll still meet "not enough memory" eventually.

Our guide to Roku storage errors covers the fix, but the relevant point here is that the Ultra's extra headroom is a genuine practical advantage over the cheaper models rather than a specification detail.

Who it's competing against

Within Roku, the Ultra is the only model with Ethernet, so the comparison is really Ultra versus stick rather than Ultra versus a mid-tier box.

Outside Roku, the same money buys mid-range hardware from other platforms — with the tradeoff being interface neutrality. Roku's home screen is less aggressively monetised than Fire TV's, which our platform comparison covers in more detail. If you value that, staying in the Roku lineup is reasonable. If you don't, the money goes further elsewhere.
