Capture Card Volume · Lvjuneng (domestic low-price tier) [In-depth Edition]

Writings seen in the group: Lvjuneng 5046b / Lvjuneng 4k40 / "that one" Last updated: 2026-10-06 (in-depth rewrite)

════════════════ 0. The 30-second verdict ════════════════ [Who it's for] Entry-level/backup card users with a 300-500 budget who only play SDR and don't care about HDR picture quality [Who it's not for] Anyone who needs HDR, multichannel for streaming, or lossless 4K60 picture quality [In one sentence] "the 500 one has lower latency than the 1500 one" (roundup conclusion); "that Lvjuneng one is enough to get you ready for gta6" (风雨兼程)

════════════════ 1. Specs and testing ════════════════

• Positioning: a domestic entry-level card; the 500-yuan 4K60 model / 240-350 used on Xianyu

• Capture formats: no RGB/YUY2 ("no rgb and yuy2"), NV12 recommended ("pick the nv12 format for the Lvjuneng")

• 4K60 is compressed, 4K30/2K60 are lossless: "normally 4k30 and 2k60 look the same as the original, both are lossless"

• HDR: capture isn't supported — the "Lvjuneng 4K60hz hdr" marketing refers to passthrough specs ("that's passthrough" "passthrough means connecting straight to the monitor, not going through the PC")

• A minor frame-rate handling quirk (a common low-end card issue): users report "capturing a 60-frame image in 60-frame mode isn't as smooth as native, and capturing a 30-frame image in 60-frame mode is smoother than 30-frame mode" (AbigQQ, speaking generally about the few-hundred-yuan tier)

════════════════ 2. Recommended settings and ways to use it ════════════════

1. Format: NV12 (don't try to turn on HDR — it's not supported; nor is RGB/YUY2)

2. If you're after picture quality: capture 4K30 or 2K60 (the lossless tiers); accept compression at 4K60

3. The upscaling player's approach (zL): "capture 4k60, output rgb24 1080p60, then upscale to 4k" — tested and "good enough"

4. Streaming setup: "Lvjuneng + obs + 大力喜鹊 xess works well" (a comment-section setup, relayed by a group member)

5. Console player test: 金俊 "tonight I tested the Lvjuneng with 羊蹄山, interpolating 30 frames to 120" "whether it's 60, 90 or 120, the result is very good, I can't feel the latency"

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

── Q1 "The Lvjuneng listing says it supports 4K60HDR — is that fake?" [Standard answer] That's the passthrough spec, not the capture spec. The Lvjuneng's capture side doesn't support HDR; "passthrough means connecting straight to the monitor, not going through the PC" (风雨兼程's own words). Want to use HDR in Veyra: this card can't, so pick the G50 (4K30 HDR) or a PCIe card (4K60 HDR).

── Q2 Is the latency really that low?

• Tested in the group: "the latency is fine"; in the roundup (a four-card comparison on Bilibili) "the Lvjuneng has even lower latency than the g2"

• Note: roundups use different test conditions and results vary a lot, so take it with a grain of salt; in practice it's at the "can't feel the latency" level

── Q3 The image is compressed / not sharp enough?

• 4K60 is this card's compressed tier ("4K60 is compressed"); for lossless use 4K30 or 2K60

• Outputting at a lower resolution and then upscaling is the value play (see zL's approach above)

• "for a bit over a hundred, this is as good as it gets" — don't hold this tier to flagship-card standards

── Q4 Some users say "the Lvjuneng stutters"?

• Isolated cases ("a guy in the group said this one doesn't stutter, the Lvjuneng stutters, so I'll try both") — down to individual/environmental differences; if you do get stuttering: switch USB ports (10G preferred), change the cable, lower the capture format (4K60→2K60/4K30)

• Cheap cards generally need attention to cooling (overheating causes dropped frames)

── Q5 How does it compare with the reference-design ms2130s cards?

• A group member's challenge: "isn't that only a little better than the 2131S? but several times the price"

• Positioning: the ms2130s is the 1080P60 entry level (around a hundred yuan); the Lvjuneng is the 4K60 tier (300-500 yuan) — want 4K, go Lvjuneng; want maximum cheapness, go reference-design ms2130s

════════════════ 4. Prices and buying advice ════════════════

• Pinduoduo new 340; Xianyu 240; used 288 (咩霸: "I picked up a used one for 288")

• "if you want a Lvjuneng you can get a new one for 340 on PDD, or 240 on Xianyu" (金俊)

• Buying reminder: make sure it's a model that supports 4K60 capture ("for the Lvjuneng, Acasis and Kuhaomi, pick the ones that support 4k60 capture"); don't be misled by the "4K60 HDR" marketing

• Positioning by use: the SDR 4K option for consoles/PC; the value answer for GTA6 prep ("enough to get you ready for gta6")

════════════════ 5. Selected quotes from group members ════════════════

• "of the domestic brands I only recommend Lvjuneng and Acasis" (up树牢)

• "the latency is fine" "pick the nv12 format for the Lvjuneng" "no problems" (风雨兼程)

• "good lord, the Lvjuneng has even lower latency than the g2" "the 500 one has lower latency than the 1500 one" (风雨兼程, after the roundup)

• "the Lvjuneng is good enough" (Serenade)

• "I don't really need hdr, I mainly just want as little image loss as possible with lower latency, and the Lvjuneng feels like a good fit" (Bug_) ================================================================

Group members' own words

"[呲牙][呲牙] I returned the Lvjuneng, what a waste of such an aggressively low price. I'll look into the computer first"

—— 大疯子 (10-08)

"My Lvjuneng 5046b — using 小黄鸭 for frame interpolation feels like it adds a fair bit of latency"

—— 無疆 (10-08)

"So the Lvjuneng's extra cost is all in the latency"

—— 易 (10-10)

"I returned the 400-something Lvjuneng [奸笑]"

—— 大疯子 (10-10)

"@易 how much input latency do you get with the Lvjuneng"

—— 大疯子 (10-12)

"I got burned by someone online who said it could do 4k60nv12 — if that's the case I might as well have bought the Lvjuneng"
