@quickguide01  If neither of the displays you have right now has a DisplayPort output in order to create a daisy chain and getting one where you're located would be expensive, then I'd recommend using one of the solutions I already described in my earlier posts.

There is a difference between display port vs display port output?  I don't know if i have a display port output on my two monitors.  But I do know i connect usb-c to display port with my Asus monitor.

 

The samsung syncmaster, i connect hdmi to hdmi...

@quickguide01  The DisplayPort you're using to connect from your laptop to your display is a DisplayPort input, because the display is receiving a video signal from your PC on that port.  A DisplayPort output is used to send a video signal out to the next display in a daisy chain.

Okay so i purchased the 32" monitor online and will be receiving it sometime soon.  I decided to do this instead of getting another one of my current monitors. 

 

So my plan would be to use the new monitor with one of my current monitors.  Now if i want to use both my current monitors and the new monitor... to have three external monitors...

 

I saw some products on amazon that are a bit cheaper as oppose to the dell docking station... but would that work?

 

Again right now im using two 24' l920 x l200 monitor side by side

 

And when i get the 32"  4k monitor, my plan was to use just one of them with this one... but if i want to use all three... what are my options?  Can someone here post the exact product I would need?  The thing is though in this situation... only one of my monitor is 4k.

 

I heard that no matter what docking station you buy etc... if you wanted to have three external monitors... you can only have max two monitors at 4k is that right?  Of course im not counting the laptop display as a monitor.

@quickguide01  It doesn't make sense to say, "I saw some products on Amazon, will they work?" if you don't even link to the products you found.  How is anybody supposed to know whether some product you found on Amazon will work if you don't even specify the product?

I already gave you your options for running a 4K display plus two additional 1920x1200 displays multiple times in earlier posts.  I even gave you a link to a specific Thunderbolt 3 to Dual DisplayPort or Dual HDMI adapter available from Amazon Mexico, since that seems to be where you're located.  Why do you keep asking me to answer the same questions over and over again?

If you only want to use a 4K display and a single 1920x1200 display, then get a USB-C to DisplayPort cable (or USB-C to HDMI 2.0 cable) for the 4K display and connect the 1920x1200 display to the HDMI output.  If you want to use all 3 external displays simultaneously, you can either get the docking station or get a Thunderbolt 3 to Dual DisplayPort or Dual HDMI 2.0 adapter -- like the one I already linked -- to cover two of your displays, and then connect one of your 1920x1200 displays to the HDMI output.  Cheaper products are unlikely to support a 4K 60 Hz display at all, and almost certainly won't support a 4K 60 Hz display plus a second display.  And you can't run a 4K 60 Hz display from your system's HDMI output.  You would only be able to run it at 30 Hz there, which isn't a great experience.

Technically you could have 3 external 4K displays, but only two of them would be able to run at 60 Hz.  The third 4K display would have to be connected to the HDMI output where you'd only be able to run it at 30 Hz.

Hey.  

 

Will this work?  I could order it on amazon.com since i know someone that will be coming to where im located so they could bring it to me.

Yes i saw the link you gave me for having three displays.  I then decided to not go with another one of my same monitors and decided to go with the 32" monitor 4K display since i never had one.

 

 


Technically you could have 3 external 4K displays, but only two of them would be able to run at 60 Hz.  The third 4K display would have to be connected to the HDMI output where you'd only be able to run it at 30 Hz.

 

If that is the case, what is the purpose of having three monitors with the 4K display at 30 Hz then if it will be lagging on the last monitor?  Im shocked by this.  But i have to assume desktop computers would allow it right?

What about these especially the first link?  

 

I have someone from the US that can buy it for me and bring it to me.  Will either of these work especially the first one?

@quickguide01  When I said it didn't make sense to ask if random products on Amazon would work without providing links, I wasn't offering to look at a bunch of links you found.  I will say this one last time:

If you want to run a 4K 60 Hz display and 2 other displays, you will need either a) a Thunderbolt 3 docking station, or b) a Thunderbolt 3 to Dual DisplayPort adapter, or c) a Thunderbolt 3 to Dual HDMI 2.0 adapter.  The multi-purpose regular USB-C (non-Thunderbolt) hubs you're finding will not tap into enough video bandwidth for 4K 60 Hz + 1920x1200 60 Hz.  That's especially true because your system only supports DisplayPort HBR2, not HBR3, which means that if you used a non-Thunderbolt USB-C device like the ones you linked, on your system you'd be limited to a single 4K 30 Hz display through that adapter.  Even 4K 60 Hz wouldn't be possible, and 4K 60 Hz + 1920x1200 60 Hz definitely would not be.  Some multi-purpose USB-C adapters like you found will support higher-end display setups when connected to a DisplayPort HBR3 system, but that's not what you have.  And that is why I recommended the solutions that I've already recommended multiple times now.

As for running dual 4K 60 Hz + 4K 30 Hz, depending on what the user planned to display on the 30 Hz display, the low refresh rate might not be an issue.  But I didn't say that somebody should do that.  I said that's all your system would handle if you wanted to run 4K on three displays.  If someone didn't want to use 30 Hz, they could instead run dual 4K 60 Hz + single QHD 60 Hz in order to maintain a 60 Hz refresh rate while still having 3 displays.  You're planning single 4K 60 Hz + dual FHD 60 Hz, so the idea of using displays that have different resolutions shouldn't be too "shocking" for you.  Or they could just run dual 4K 60 Hz displays.  Running triple external displays is still a relatively rare setup overall.  But someone who wanted to run triple 4K 60 Hz external displays would not be able to do that from your system.  Yes, some desktop GPUs would be able to run that.

Good luck with whatever you end up buying.  I don't really have anything else to add here.  I've explained the options you have if you want to run 4K 60 Hz + 2x 1920x1200.  I am NOT going to keep telling you why every other random product you find will not work.

Someone in another forum said 
 
Nope, I mean USB 3.0 Type A to HDMI adapter. You don't have one, yet.

This way, you'll have USB C cable for 4k display, HDMI to HDMI for first FHD, and USB A to HDMI for second FHD.
 
 
Is it one of these that I need?

@quickguide01  Don’t use USB-A adapters. They rely on “indirect display” technology like DisplayLink — not to be confused with DisplayPort — and that can have significant drawbacks for some use cases, which I’ve written about in the post marked as the answer here.  I’ve already explained that you need a Thunderbolt 3 to Dual DisplayPort or Thunderbolt 3 to Dual HDMI 2.0 adapter. The USB-C MST hubs that you found for much less cost look very similar, but they are NOT the same because they only use regular USB-C, not Thunderbolt.  And therefore when used with your system, they will not have enough bandwidth to run a 4K 60 Hz display and a 1920x1200 display simultaneously. You need a device that taps into Thunderbolt 3 to run that display combination from your system’s USB-C/TB3 port. Again, I already provided a link to a page on Amazon Mexico to an appropriate Thunderbolt 3 adapter, and it even had options for whether you wanted Dual DP or Dual HDMI outputs. And then you can connect your other 1920x1200 display via HDMI. If you get that equipment, then the triple display setup you are envisioning will work. If you keep trying to find cheaper alternatives, then it either won’t work or won’t work as well, such as the DisplayLink scenario I linked above. But I’ve already told you multiple times what will work. As I already said, I’m not going to spend even more time now explaining why every possible alternative you find by searching around Amazon or asking people about this on other forums will NOT work. But if you want to trust their opinions instead, go ahead.

Hi thanks for the response.  I always thought usb-c and thunderbolt three was the same thing?  I know my xps has thunderbolt three and the cable i use for one of my monitors now is usb-c to displayport etc.

 

Well could i attempt to try a usb-a?   This was the link the guy in another forum gave me and said it would work.  But i thought one issue though is isn't it only I080p and well my monitors are l200 vertical?  

 

https://www.amazon.com/Converter-Multiple-Monitors-Compatible-Projector/dp/B08KY7T3MG

 

Yes im in Mexico but i have a friend that is coming from the US soon so he could get me something from amazon.com. 

 

I checked the thunderbolt to dual hdmi or displayport and those seem to cost at least 90 dollars or so.  So its either that or spend over hundred fifty for the docking station then right? Yea i ask lot of these questions because i dont want to spend a lot on it... if there was a cheaper option on this.  Why is it so expensive compared to the usb-c to displayport or hdmi cables though i have two of those cables at the moment with me.

@quickguide01  USB-C and Thunderbolt are not the same thing. USB-C is just a connector shape, and many features associated with USB-C are optional, such as system charging and video output. Thunderbolt 3 is a completely different standard that uses a USB-C connector but does a lot more. Read my explainer post here.

You can try whatever you want. If the poor performance and additional CPU utilization of USB-A adapters and the restriction of not being able to use your NVIDIA GPU with the display connected over USB-A aren’t a problem for you, then yes that’s certainly a cheaper option. But if you want all 3 of your displays to be driven directly by the GPU in order to avoid the drawbacks of technologies like DisplayLink and you want to be able to use your NVIDIA GPU for all 3 external displays, then you’ll need a solution like I described based on the resolutions of your displays and the capabilities of your system. If those solutions are too expensive for you, then unfortunately you’re trying to achieve something too expensive for your budget. In that case, limiting yourself to only running 2 of your 3 external displays at a time would be worth considering, since that would avoid needing those more expensive products.

Hi, thanks for the response again.  But what that poster suggested... that might possibly work right?  At first i didn't understood what he meant with the usb-a etc... but then i found out it meant oh you just connect it to one of the usb ports on my laptop...   I was wondering where in the world i would even connect this cable from my cable because i thought... hey i only have a usb-c/thunderbolt port and an hdmi port on my laptop... so where would that cable connect from on my laptop.

@quickguide01  You’d plug it into one of the USB-A “regular USB” ports on your system. The XPS 15 9550 has some of those. As to whether it will work, I already wrote a reply about that earlier where I explained that USB-A adapters rely on “indirect display” technology that is very different from using a native GPU output, and I linked to a thread where I wrote a detailed post explaining some of the drawbacks you can encounter with those solutions compared to using native GPU outputs. If you didn’t read that thread, I suggest that you go read it. Because yes the adapter might work in the sense that you’ll see an image on the display, but you might notice some unacceptable performance tradeoffs when using that type of solution.
