Capture Card Volume · ASUS TUF GAMING CAPTURE BOX-4KPRO (CU4KPRO) [In-Depth Edition]

[Important Update · 2026-10-06] The ASUS 4KPRO has gone up in price; the clearance low-price window is closed.

Every low price in this article (499 / 660-799 / 750-900, etc.) is a historical market price; don't look at this card through the lens of "so worth it / king of value for money" any more — before buying, be sure to compare current prices against models that are still on sale, such as the Kuhaomi G50 (same solution, with firmware maintenance and after-sales support). One-line positioning: the same solution as the G2, NV12 4K60, bare capture 33-35ms; but the HDR 8bit banding is confirmed, it is discontinued with no firmware, and the price has already gone up — read Q2 in Chapter 3 before buying. Last updated: 2026-10-06 (in-depth rewrite)

════════════════ 0. The 30-second verdict ════════════════ [Who it's for] Only consider it when "the current price is clearly lower than same-solution cards such as the Kuhaomi G50"; users who mainly do SDR 4K60 and can accept 8bit HDR [Who it's not for] HDR image-quality enthusiasts (the 8bit banding can't be fixed), users who need 5.1 multi-channel (stereo only), users who need long-term firmware maintenance [In one line] "we've dug up every single thing you can criticize the ASUS for" "the only thing we can't criticize is its price" (Hi, before the price rise); now the price has gone up too — compare prices rationally before buying.

════════════════ 1. Specs and capabilities ════════════════

════════════════ 2. Recommended settings (follow step by step) ════════════════

1. [Wiring] PS5 → capture card IN; OUT → monitor (connecting the passthrough is recommended); Type-C → the motherboard's 10G port
2. [USB port] the orange USB3.2 port on the back of the case / Type-C; pick one wired directly to the CPU, don't use the chipset (it adds another layer of relay); without a 10G port → only 4K60 MJPEG (not recommended); if there's no A port, go C-to-A — "buy a 3.2gen2 adapter, 10 yuan each"
3. [Self-check before installing] Go to the motherboard's official site and check for "USB 3.2 Gen2" support (case: a mid-range B760M model only has gen1 — a wasted purchase)
4. [Capture format] NV12 4K60 for SDR; P010 4K30 for HDR (+ manual PQ hdr10)
5. [Troubleshooting reddish colors] Unplug the passthrough cable and try once (Han's case: "I unplugged that passthrough cable and it solved the problem instantly")
6. [Where to test] First use OBS to verify the capture frame rate and colors, then go into Veyra

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

── Q1 [High frequency] Plugged in but no picture / yellow light flashing alternately / passthrough frozen / "can't connect" [Symptom] After connecting it never connects; "input error" appears during transmission; the yellow light flashes; the passthrough picture freezes [Cause] The HDMI handshake between the PS5 and the capture card fails ("a yellow light means handshake failure" — 咖喱); the passthrough signal source has a format conflict [Fix] Troubleshoot in order (a merged flow from two complete cases in the group):

1. Check the three cables: PS5 HDMI → capture card IN; capture card OUT → monitor ("try plugging the out cable into the monitor as well" "plug in both in and out"); Type-C → the computer's USB3.2 port

2. Turn off HDCP on the PS5 (Settings → System → HDMI → Turn off HDCP)

3. Locate by the light: yellow = HDMI signal disconnected / handshake failure ("alternating yellow flashing = handshake failure")

4. Connect the PS5 directly to the monitor to verify the two cables themselves are fine ("try both cables straight from the ps5 to the monitor")

5. ★Key step (the group's solution): "the signal source going into the passthrough may have a format conflict" "just restore that hdmi signal source of the passthrough to default" "check whether you've turned on some hdmi enhanced mode or 60hz low latency thing" "vrr" (Yoloッ)

6. Step down on the PS5 side: drop the color one notch, change the output rate to -1 (咖喱: "when I first used it last night, the ps5 was outputting 4K HDR RGB and the passthrough froze so badly it couldn't move" "it only stopped stuttering after I changed the transfer rate to -1")

7. Swap in the PS5's original HDMI2.1 cable; try the other C port

8. If all of the above fails: contact after-sales for a replacement (some people got cards that were dead on arrival) [Related] "using passthrough and capture at the same time takes up HDMI bandwidth, you have to adjust the output format" (Hi) — 4K HDR RGB passthrough is the most prone to problems

── Q2 [Core] HDR color banding (8bit confirmed) — must-read before buying, no fix once bought [Symptom] The HDR (4K30) capture picture shows obvious color layering/banding; but you can't see it in the passthrough signal [How it was confirmed] 张威伦 (devices: TV G6 + miniled monitor, verified on both devices): "compared with the passthrough signal, the asus 4k30hdr capture signal has obvious color layering" "even if it originally existed it should have been extremely slight, and you can't see banding in the ASUS passthrough either, but the capture signal is very obvious" — "the clouds have rings of color layering" [The group's verdict]

• Hi: "asus hdr8bit, don't buy it" "avoid asus" "next time someone says asus is good, we'll just say 8bit" (the famous moment from 09-21)

• DRAKE: "the capture card is physically incapable, software can't solve it" "ASUS's color banding plus no follow-up firmware support is a fundamental flaw"

• For comparison: En tierra (compared on two OLEDs): "the g2 doesn't have it, I compared on two oleds and the g2's colors are even a bit better than the ps5's native hdr" "the 573's color banding is because it only supports 8bit"

• "they measured the 573 as 8bit, and the ASUS is suspected to be 8bit too" → 牛腩盖饭 confirmed: "the ASUS is 8" [Remedies worth trying (they improve it, they don't eliminate it)]

1. NVIDIA control panel: "switch it to n-card control" "don't use monitor control"; change the default color depth to 12bit — "I just tried changing the color depth from default to 12bit in the n-card settings and the color banding improved" "but there's still a bit" (Deathwing, tested)

2. Try both limited and full color range on the PS5 (张威伦 already tried it: "still layered")

3. Check the monitor side: turn off "dark area enhancement", and watch out for miniled / 8-bit-dithered-to-10-bit panels amplifying the problem [Conclusion] This is caused by 8bit in the hardware chain; software can't fix it. If you care about HDR image quality: ① just use SDR 4K60 NV12 (this card is very stable in SDR, 33-35ms); ② or spend more on a 10bit card (G2 / mk2 / 4K Pro)

── Q3 How do I confirm my computer can run it before buying?

1. Check the motherboard: whether it supports USB 3.2 Gen2 (10Gbps) — "the most direct way is to see whether there's an orange usb port on the back of the case" "just go to the official site and look up the motherboard model" (mid-range boards such as the B760M may only have gen1)

2. gen1 (5G) users: can only run "4K60 MJPEG" (poor image quality, high latency, not recommended); or change the motherboard / use an adapter

3. For Veyra: without a 10G port you can't run 4K60 NV12 — you must check before buying; there's a case of a group member who bought one for 679 and then returned it

── Q4 "How do you tell the 4K30 and the 4KPro apart?" (avoiding the trap)

• Look at the printing on the right side of the front: "the right side of the front of the 4kpro seems to say tuf gaming, on the 4k30 it's asus"

• "one is first generation, one is second generation" "these two cards look exactly the same"

• There was once the mix-up of a store "listing the 4K30 but delivering a 4KPro" (a win for the buyer), but group members warn "some sellers will sell the 30 model"

• 4K30 users have run into "there's no EDID choice at any resolution, it's probably hard-coded into the firmware"

── Q5 How do I get Dolby Atmos? (this card is stereo only) The solution (Hi's standard play): ASUS 4KPro + an audio extractor — "for Dolby Atmos I defected from the AVerMedia g2 to the ASUS 4kpro + audio extractor" "the audio went from a crippled 5.1 to a full-powered one, the only problem is that the wiring got a bit complicated" (a comment based on the clearance price at the time; recalculate at the current price) Wiring: PS5 → extractor → one path to the power amplifier, one path into the capture card (see the audio chapter of doc 05 for details)

── Q6 Heat / cooling

• It's normal for the external box to get warm; the group has no demand for dedicated cooling mods (compare the 573, where a 4cm fan is a hard requirement)

• Driver-free design, plug and play; the firmware is stuck at the version it was discontinued with

── Q7 How much latency? How does it compare with other cards?

• Bare capture 33-35ms ("bare capture is around 40ms, but from yesterday's testing it came out at 33-35ms")

• OBS comparison: g2 59ms vs ASUS 62ms (the whole OBS chain runs slower, on-device it's lower)

• 4K30 HDR latency: around 90ms (HDR capture latency doubles, not recommended for gaming)

• Comparison: the same solution and the same latency tier as the GC553G2; it can't beat PCIe (the 12-33ms of the 573/mk2)

════════════════ 4. Price history and buying advice ════════════════ [Price history (historical market data · expired)]

• Original price 1800-2000; clearance: 499 (snagged in group 1) → 660/675/685/693/698/699/718/719/750 → 799

• Famous moment: on 2026-09-18 everyone in the group had one; Likely7: "sold like crazy" "what are you all doing"

• 09-23 金俊: "the ASUS used to sell for over 400 in the clearance"; DRAKE: "500 I think is okay" "at 700 you might as well pay more for the G2" [Current status (2026-10-06)] The clearance is over and the price has already risen ("it used to be 600, now it's almost 800 or 900"); stop waiting for a bargain price [Buying advice]

• Compare with same-solution competitors: the Kuhaomi G50

• Only buy the Pro version: look for the "tuf gaming" wording; on Pinduoduo, beware that "Pinduoduo won't give you a return"

• Positioning by use: fine for SDR 4K60 gaming/streaming; don't count on HDR

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

• "the ASUS is a proper same-solution card as the g2" "the ASUS is the youth edition of the g2"

• "asus hdr8bit, don't buy it" "the only thing we can't criticize is its price" (before the price rise)

• "even if it originally existed it should have been extremely slight, and you can't see banding in the ASUS passthrough either, but the capture signal is very obvious" (张威伦)

• "the capture card is physically incapable, software can't solve it" (DRAKE)

• "the ASUS is much smoother" (a user who switched cards, SDR scenario)

• "compared with the Kuhaomi G50, the ASUS's biggest shortcoming is that it's been discontinued and there are no more firmware upgrades" (DRAKE) ================================================================

New questions & answers

Q1: @宇宙最强采集卡:华硕4KPro how do I download this (🤫 10-23)

A: @宇宙最强采集卡:华硕4KPro @variable try whether the new version is stable (Likely7 10-27)

Fixes and reminders

• I returned all my 4kpros, my computer can't recognize it even with the driver installed (阿莫视觉 10-24)
• I have an ASUS z790, I updated the bios, pulled the m.2, tried every method and it still doesn't work (阿莫视觉 10-24)
• Let me give an example: when I play Onimusha there's a vrr mode, but vrr only works if you enable 120hz. If the capture card doesn't support 4k120hz capture, then you can only enable 1080p120hz to use vrr. The 4kpro can do 4k120hz with vrr, but in that case you can only use nv12 and can't use HDR, the pic… (A 10-24)
• Mainly it's for face protection @宇宙最强采集卡:华硕4KPro (the author 10-18)
• That would work, but there are no more mk2 bargains to pick up now, wait for a good 4kpro price (Taka 10-28)
• I've always used the 573, and a couple of days ago I wanted to finish the Prince of Persia: The Lost Crown platinum. But as soon as I went in it was really blurry, and when I plugged straight into the monitor it was crystal clear, so I'm thinking of buying a 4kpro to try again (Stony 10-06)
