Go to the Displays preferences panel.
Click “Advanced…”
Select “Show resolutions as list”. Click “Done”.
Select “Show all resolutions”.
Do you see a 2560×1600 mode now?

If not, then try using SwitchResX or BetterDisplay to switch resolutions?

As a last resort, you might need to delete some display preferences files:

Once you have 2560×1600 working, have a look at this thread:

I don’t think MST hubs have different firmwares for dealing with HDCP.

What display are you having a problem with?

Did you verify that the display doesn’t have black screen issue when connected directly (without the MST hub)?

I have a display that does go black momentarily periodically if the brightness is set over 80%. I think it’s getting old.

What chip does the CSV-7200H use? If you can get the DPCD info, it may have the information.

If it’s a Synaptics chip, then you can get some utilities in the Microsoft App Store that can get more info, backup the firmware and update the firmware (if you have an updated firmware).

The CSV-7200H does not use the same firmware as the CAC-1010

[joevt]

The Ethernet port is a USB Gigabit Ethernet adapter. Maybe you can find the manufacturer and download an update driver from them if one exists?

Another option is a utility like Driver Genius 25 from driver-soft.com which can scan your list of devices and install updated drivers for each.

Is it the Club 3D CSV-1564W65 USB Gen1 Type-C Triple Display Dynamic PD Charging Dock ?

The CSV-1564W65 appears to use a DisplayPort 1.2 MST hub limited to two lanes of HBR2. The total pixel clock for all displays must be less than 360 MHz (assuming RGB 8bpc).

You are connecting only one HDMI display so it should be able to handle 4K30 (297 MHz HDMI) or 1440p60 or 1080p120.

The CSV-1564W65 must be connected using a USB-C 5 Gbps or 10 Gbps or 20 Gbps or passive Thunderbolt 3 or 4 or 5 cable to a USB-C or Thunderbolt or USB4 port that supports USB-C DisplayPort Alt Mode.

A charging cable is not sufficient. You should be able to connect USB devices up to 5 Gbps to the dock. If that’s true, then the cable is ok.

Is your Acer model number this: Acer Nitro V 15 ANV15-51-50Z1 | NH.QNAAA.003 with RTX™ 2050? It appears that the only USB-C DisplayPort Alt Mode capable port is the Thunderbolt 4 port.

Do you have any USB-C to DisplayPort or HDMI adapters or cables that can be used to test the video output of the Thunderbolt port?

[joevt]

List the model numbers of your docking station, laptop, and display.

There are many Acer Nitro V15 models.

Club-3D has multiple docks.

Different displays may have different HDMI requirements.

[joevt]

“UHBR20”, “80 Gbps”, “VESA DP80 Certified”, all mean the same thing – that the cable supports the max bandwidth of DP 2.1. All other descriptors are superfluous. The certification is a bonus but something that you should look for in any DisplayPort 2.1 cable.

The cable has the CAC-1091 tag on it?

It would be interesting to compare a picture of your box with that of the product page.

4K240 has a pixel clock of at least 2285 MHz. UHBR20 can do that without DSC up to 10bpc which is sufficient for HDR.

The CAC-1092 appears to be just a longer version of the CAC-1091. I don’t know why the product pages show different lists of resolutions. It’s confusing. Maybe it should just show maximum pixel clocks.

These max pixel clocks for UHBR20 don’t include FEC:
8bpp: 9671 MHz
9bpp: 8597 MHz
10bpp: 7737 MHz
12bpp: 6448 MHz
18bpp: 4298 MHz
24bpp: 3224 MHz
30bpp: 2579 MHz

CVT-RB2 timings:
3840 x 2160 60 Hz 522.614 MHz
5120 x 2160 60 Hz 693.264 MHz
5120 x 2880 60 Hz 924.144 MHz
6016 x 3384 60 Hz 1273.210 MHz
5120 x 2160 120 Hz 1427.088 MHz
5120 x 2880 120 Hz 1902.576 MHz
7680 x 4320 60 Hz 2068.660 MHz
3840 x 2160 240 Hz 2285.203 MHz
6016 x 3384 120 Hz 2620.304 MHz
10240 x 4320 60 Hz 2751.105 MHz
7680 x 4320 120 Hz 4258.377 MHz
10240 x 4320 120 Hz 5663.203 MHz
7680 x 4320 240 Hz 9045.676 MHz

[joevt]

That cable should also work.

[joevt]

Which cable are you looking at? I think the cable you want is the CAC-1092 which is 1.6m/5.25ft.

77.37 Gbps, or 80 Gbps, DP80, or UHBR 20 are all indicators of the max DisplayPort 2.0/2.1 bandwidth.

“VESA DP80 Certified” is a certification that the cable can do the max bandwidth.

Every other descriptor is unnecessary when it comes to quality or bandwidth.

HBR3 is a DisplayPort 1.3/1.4 link rate that is 40% of UHBR 20. A UHBR 20 cable can do all the DisplayPort link rates but the product page does not clearly state this. It says “Downwards compatible to older DisplayPort™ standards” but doesn’t say it supports the lower link rates or connecting to DisplayPort 1.1/1.2/1.4 sources and sinks. One part that is confusing is the description of a “New DP2.1 spec connector” or “NEW DP80 connector” or “NEW contact fingers special designed for these high speeds”. Are these new male connectors compatible with old female connectors? If so, then this may be a case of TMI (too much information).

 

[joevt]

Shouldn’t there be a downside somewhere to using HDCP OFF? Or does HDCP OFF add HDCP support to a non-HDCP display?

[joevt]

How does HDCP OFF change the behavior?

I guess fuzzy happens when the display is assumed to be HDCP but doesn’t handle HDCP?

If it’s HDCP OFF, then it means Netflix won’t play videos on that display, but at least it won’t do fuzzy?

[joevt]

Define “didn’t work”. Did the Satechi hub work with one monitor connected? Did it work with two monitors connected using lower refresh rate?

What is your Laptop? Does it support two displays from Thunderbolt 3/4 or USB4?

The Asus VG279QM1A is only DisplayPort 1.2 or HDMI 2.0 so two of them should be able to work from Thunderbolt 3/4 or USB4.

[joevt]

You could also try reporting the issue to Nvidia and ask for an option to disable DSC from all or some of the ports of the Nvidia GPU.

[joevt]

DVI is basically HDMI. Just need a passive HDMI to DVI adapter or cable. HDMI is single link so it will be limited to 1920×1200 or less.

No HDCP info means the EDID does not specify whether HDCP is supported or not. This info if it exists would be in the extension block. Your extension block is all 0xFF bytes which is not valid.

[joevt]

That EDID doesn’t have HDCP info. The extension block is invalid. Is the EDID the same if you use a HDMI connection instead?

Although this forum does have the [ code ] / [ /code ] commands, it doesn’t seem to be able to preserve indenting when pasting text:
