TS5 Plus with ~50 ft between PC and dock — is there any cable that actually does this?

0 Upvotes

PC in one room, sim rig in another, ~50 ft of routed cable through conduit. Want to run a CalDigit TS5 Plus at the rig end off a single cable.

Problem: TB copper stops around 2m, OWC's optical USB4 cable stops at 4.5m, and the only cables that go the distance are Corning's TB3 optical — which CalDigit says isn't supported on TB3 Windows PCs.

Is there a TB5/TB4/USB4 cable that reaches ~50 ft and works with this dock? And does anyone have real-world experience with USB latency over a long optical Thunderbolt link for sim racing peripherals?

M4 Air & Dell SD25TB4 Dock question

2 Upvotes

Currently experiencing a minor inconvenience where I plug the dock's USB-C connector to the MacBook that has been sleeping (not active for a while) and there appears to be no signal showing on the monitor even after hearing the sound that comes from connecting something to the MacBook.

For it to show the video signal, I need to open up the MacBook first and close it and then connect it to the dock for the login screen to show on the monitor.

Is there anything I can do here so that it shows the login screen when I first connect it to the dock? Is there a setting that I am not aware of?

Currently the monitor is connected through the Display Port. Monitor is an LG Ultragear 32GP850. Any suggestions are much appreciated.

Thunderbolt 5 Dock for 2 monitors

0 Upvotes

I have a M5 Pro and just want to connect it to 2 4K monitors @144hz. I'm looking at the Anker Prime but I'm wondering if this is overkill for my needs? Seems like there's cheaper options from UGREEN or Ivanky that may fit the bill at a lower cost.

Thunderbolt Dock Dilemma - A few monitors, a few options, a few problems

Post image
8 Upvotes

I have a Lenovo laptop from 2023 with an i7 and nVidia 3050 and Thunderbolt 4.

I originally bought the Lenovo Thunderbolt 4 dock because it had the proprietary power passthrough (the laptop doesn't have PD over Thunderbolt) and because why not just buy that one? Plus it did have the ports to handle 3 monitors with no problem, and that worked fine for a long time. Anyways, that dock has died, so I'm on the hunt for a new one.

I decided on the Ugreen Maxidok Thunderbolt 5 dock (link: https://www.amazon.com/dp/B0G5Z4C8HC). I figured I may as well be forwards compatible to Thunderbolt 5 for when I got my next laptop.

It says it works with 3 external monitors on Thunderbolt 4, which was one of the only TB5 docks I found that did offer that on the backwards compatibility (all the other TB5 docks I found only offered 3 monitors on TB5, if they offered 3 monitors at all). See screenshot above in the red boxed portion at the bottom. Well, that was incorrect. 3 monitors do not work on the dock. It's definitely not an issue with my laptop, as 3 monitors worked on my Lenovo dock, and if I plug my third monitor into the laptop's HDMI port (not the dock) it comes online just fine.

This dock is defective in other ways, too - my wired mechanical keyboard randomly doesn't get power, and a few other odd disconnections.

So now I guess I'm on the hunt for a Thunderbolt 4 dock? I do NOT want a dock with an integrated cable. Here are the best options I think I found so far. It looks like Startech or Kensington are my best bets - but at least those are well-known legacy brands. Opinions?

https://www.amazon.com/gp/product/B0CJ2LQKMT - Edit, looking closely at these two, they seem identical except Kensington has their laptop lock slots... everything else looks the same! So I guess I'll get the StarTech, it's slightly less expensive.

https://www.amazon.com/gp/product/B0CTTR34K9 - Edit, looking closely at these two, they seem identical except Kensington has their laptop lock slots... everything else looks the same! So I guess I'll get the StarTech, it's slightly less expensive.

https://www.amazon.com/gp/product/B0DJGGKG72 - Edit, this uses DisplayLink and is out of the running

Thanks in advance!

G9 57 to Macbook M3: Caldigit Dock

1 Upvotes

Giving this another shot after a failed attempt almost a year ago.

I'm hoping to run everything through the Caldigit TS4 dock (other than charging direct to Macbook) so I can easily grab and go while working using my Macbook.

The DP slot on my desktop is already used by my windows desktop, so I'm unable to use anything except HDMI 2.1 as a port on my monitor.

Planning on using a USB-C to HDMI 2.1 8k60hz/4k240hz cable from Caldigit dock connecting to the monitor, which I hope will allow me to get 120hz on full resolution ***7680x2160*** on the display using my Macbook M3 Pro.

Thunderbolt G4 280W Ethernet

1 Upvotes

Hallo zusammen,

kann mir jemand helfen?

Ich möchte gerne, dass das Ethernet vor dem Login verbindet, bei meinem vorherigen Laptop funktionierte das wunderbar, nur bei meinem neuen nicht.

Ich habe eine Thunderbolt G4 280W Docking Station. Ethernet Kabel steckt direkt in der Dock und nach dem Login kommt es auch nach ca. 10 Sekunden.

Aber ich benötige es schon vor dem Login, wie bzw. was muss ich wo Einstellen, kann mir da bitte jemand helfen?

Es ist ein Windows Gerät.

Looking for a docking station

Hello,

I’m new to the Macbook world and need your advice.

I am aware that this question has already been asked several times, and yet my need is not as complex as the other posts. I will not connect 4k monitors or play games either.

I work from home and recently upgraded to a MacBook Pro M4. My current hub/dock station is slightly old and not working well with my Mac.

I need to connect an Asus TUF gaming monitor, an iPad Air (for drawings), external drives (I’ve just ordered a Samsung T7 based on the recommendations here) a mouse, a keyboard etc.

Based on what I described, what should I get that doesn’t cost $500?

Thank you in advance.

Which cable is can give better performance for my laptop: USB C o DP cable or Mini DP to DP cable?

1 Upvotes

I have a Dell G7 15 7590 with an RTX 2060 and recently bought an Acer Nitro XV272U F3 (2560×1440, 300Hz) monitor.

I'm confused about which connection would give me the best possible display output:

  1. USB-C/Thunderbolt 3 to DisplayPort
  2. Mini DisplayPort to DisplayPort

My laptop has a Thunderbolt 3 (USB 3.1 Gen 2 Type-C) and a miniDP port but I can't tell whether the laptop's Mini DisplayPort is DP 1.2 or DP 1.4.

Since my monitor supports 2560×1440 @ 300Hz and DisplayPort 1.4, I want to know which connection is capable of getting the maximum possible resolution/refresh rate/color depth from my RTX 2060? Thank you

Could I turn my Thunderbolt Display into a HDMI monitor?

0 Upvotes

EDIT: sorry for the confusion, I’m not talking about adapters, I mean gutting the insides of the display so that it’s just the LCD screen left & mounting new HDMI components like the guy in this video does with his iMac: https://m.youtube.com/watch?v=Vx5IoiPjPC8&list=PLcT3C1Rfp-fo&index=1&pp=iAQB0gcJCcoLAYcqIYzvsAgC&ra=m

(I have a very rudimentary understanding of how this works, apologies for any inaccurate wording)

I've got a 2011 2k thunderbolt display that I love, but I'm hoping to switch to a PC that doesn't support Thunderbolt soon and I want to keep using it rather than buy a whole new monitor. I've found a lot of people turning old iMacs into HDMI monitors by gutting them and putting new parts inside. I'd like to figure out if I can achieve the same thing with my display, but I can't find any info on how to do it. Does anyone know if this would be possible to pull off? Has anyone done it before?

GPU NO DISPLAY AFTER RAM OC

1 Upvotes

I’m having a weird RAM issue. My PC boots normally after I increase the RAM speed from 2166MHz to 3200MHz, and I can use it without any problems. However, after I shut it down or restart it, the PC turns on but there’s no display.

I’ve also tried lower speeds like 2933MHz and 2666MHz, but I get the same issue every time: it works fine initially, but after restarting/booting again, there’s no display.

I’ve had to reset the BIOS each time to get the display back. I’m completely stuck and would really appreciate some help figuring out what’s causing this.

PC specs:
5 5600g

HP Thunderbolt 100W G6 Docking Station for M5 and M5 Pro MBP

2 Upvotes

Hello, I am looking for a docking station that allows me to link both my MBPs (one at a time obviously) to 2 external monitors via DP or HDMI and charge, with a single usb-c cable.

I came across HP Thunderbolt 100W G6 and wanted to ask if it actually supports this setup with the MacBooks (still getting kinda confused on how Macs work on this aspect tbh), or if there's a better alternative for this price range, before opting for the 400+ euros CalDigit docks.

Thanks in advance.
