Capture Card Volume · UGREEN [In-depth Edition]

One-line positioning: a "general merchandise brand" spanning tens of yuan up to 700; the CM series is highly flaky, the UG701 needs the right version,

and the new FPGA model is acceptable — the group consensus: "of UGREEN's cards, only the UG701 is recommended (and you must buy the 8K passthrough version)". Covered in the group: CM700 / CM701 / UG701 (4K60 version, 4K144 version) / FPGA design / the low-price models at each tier Last updated: 2026-10-06 (in-depth rewrite)

════════════════ 0. The 30-second verdict ════════════════ [Who it's for] The UG701 (8K passthrough version) as a 400-700 yuan stopgap card; the tens-to-hundred-yuan models as "just messing around" consumables [Who it's not for] Anyone serious about gaming/streaming (the CM700/CM701 are far too flaky); anyone with picture-quality demands when using DLSS5 (poor encoding flickers) [In one sentence] "this UGREEN capture card is absolute trash" "it died after a few uses" (a CM701 user); but the UG701 is the only UGREEN model the group endorses.

════════════════ 1. Model lineage and testing ════════════════ [CM700 (avoid)] the one-to-two-hundred-yuan tier

• "I used the UGREEN cm700 before — the image went grey and the latency was huge, returned it straight away" (L)

• "whichever mode you set, the colors are a bit odd, and the latency isn't much different from streaming" (大小年)

• A rare positive: "a group member's UGREEN cm700 looks decent, two or three hundred is just right" (Sluxiya) [CM701 (avoid · the most notorious failure case)]

• yyt's complete failure log: abnormal image ("there's this thing above the head") → all three apps (Veyra/OBS/PotPlayer) abnormal → the author investigated: "then it's most likely a capture card problem" → the user's conclusion: "this UGREEN capture card is absolute trash" "it died after a few uses"

• Support's line: "100ms latency" (there was a warning sign before buying) [UG701 (the only recommended model, and you must pick the right version)]

• 过气歌手's full explanation: "go buy a UGREEN ug701 on Xianyu, the one that supports 8k passthrough; it should do rgb at 4k, and it's only 400-something" ★"if you buy the 4k passthrough one, its encoding is terrible; you have to buy the one that supports 8k passthrough, only then is its 4k encoding good" "mine right now is the 4k passthrough UGREEN, I can only use the worst encoding format, I'm numb" ★"with the worst encoding format dlss5 flickers really badly, so I'm stuck using the next encoding tier up, but then it's only 4k30"

• Version situation (寻音之影): "the UG701 has 2 versions, 4K60 and 4K144" "4k144, 700 used" "if you have the money get the UG701, 4k144; there's another 8K one, don't buy it" (*this differs from the earlier claim that "the 8K passthrough version is better", so before buying be sure to confirm every item with support: passthrough spec / encoding format / capture spec) [The new FPGA model]

• Officially claimed 30ms; "I bought a UGREEN fpga design one"; "officially claimed 30ms" (再沉默地梳理)

• "rgb isn't compressed" "it cuts the compression-processing latency"; tested "the latency is fairly low" (5G port, 4K30 ceiling) [The low-price models] the 80-something one is "really lousy, the latency is deadly"; the 120-yuan one "works"; the 160-168-yuan one "you have to select 4K as the input, if you select 2k it actually gets blurrier"

════════════════ 2. ★Complete troubleshooting manual for common problems (ready to copy and use) ════════════════

── Q1 Which UGREEN model should I actually buy? [Standard answer] Only the UG701 is recommended, and buy the version that "supports 8K passthrough" (only that one has good 4K encoding); the 4K passthrough version has poor encoding and flickers badly with DLSS5 — that's the easiest pitfall when buying. Budget 100-200: the UGREEN CM series isn't recommended; at that price look at a reference-design ms2130s (1080P60, 40ms class)

── Q2 After a while the image goes wrong / the card just dies?

• The CM series already has a complete failure precedent (CM701: "it died after a few uses", all three apps abnormal, fixed by swapping the card)

• How to tell: check in OBS/PotPlayer first — abnormal everywhere = a capture card problem; abnormal only in Veyra = send the logs

• UGREEN after-sales goes through official channels; CM700/CM701 owners are advised to just return or exchange

── Q3 The image looks grey / the colors are odd?

• Typical causes: a low encoding tier ("the image goes grey"); poor color handling on low-end cards

• Fix: first switch to a higher encoding tier (or, if it's a UG701, pick the right version); if that doesn't help, the card itself is no good ("returned it straight away")

── Q4 Occasional electrical buzzing?

• Case: "the few-dozen-yuan UGREEN.. the latency really isn't high, it's just that there's occasional buzzing" → "that should be interference"

• Fix: check cable shielding / port interference; in the software "Professional Mode → Audio Compensation" can mitigate it; or take the audio directly from the console

── Q5 On the 160-yuan model, should the input be 4K or 2K?

• That model's user, from testing: "you have to select 4K for the input, you can't select 2k — it actually gets blurrier"

• A dark image: caused by HDR being turned off automatically when the console (NS2) doesn't support HDR — not a fault

════════════════ 3. Price reference ════════════════

• Low-price models: 80-something / 120 / 160-168 yuan

• UG701: new 400-something; the 4K144 version is 700 used

• FPGA model: a new product (price follows the market)

• Budget positioning: "if you're just messing around, a 100-something UGREEN for native 1080P is fine too" (q178310972)

════════════════ 4. Selected quotes from group members ════════════════

• "this UGREEN capture card is absolute trash" "it died after a few uses" (yyt)

• "I used the UGREEN cm700 before — the image went grey and the latency was huge, returned it straight away" (L)

• "you have to buy the one that supports 8k passthrough, only then is its 4k encoding good" "with the worst encoding format dlss5 flickers really badly" (过气歌手)

• "I looked at a UGREEN capture card for a bit over a hundred, but support said 100ms latency" (十三.)

• "I bought the UGREEN 1080 one for 80-something yuan, really lousy, the latency is deadly" (ГΛCΛI) ================================================================

This update (2026-11-05)

• At 4K only MJPEG works (the author, 10-20); the CM700/CM701 are still not recommended.

Fixes and reminders

• The 派威 VD05 and the UGREEN CM701 both support 4K60hz (花仁 10-21)
• Mine works plugged into the PC's usb3, but that UGREEN one seems to need an extra cable for power (Middle C 10-17)
• It won't capture — the UGREEN 5g port @Alex.威 (the author, 10-20)

Group members' own words

"I got burned by UGREEN — a hundred-yuan capture card that can only do mjpeg at 1080p60"

—— HM (10-12)

"I tried a 200-something UGREEN; capturing at 2K has obvious graininess, I figure that card is just bad"

—— MoserK ctrl (10-12)

"@大疯子 this is the UGREEN cm701 I bought before, then returned"

—— GFTS (10-14)

"of UGREEN, only the Xianyu ug701 is recommended"

—— new (10-15)

"I'm still waiting for my UGREEN cm701 to arrive; the paper specs look good, I'll test it when it gets here"

—— chenwangwei (10-15)
