Max # of monitors on a T530 (or W530)

#1 Post by cadillacmike68 » Fri Apr 24, 2020 10:15 pm

Can you use three monitors in extended desktop mode with one being the ThinkPad's own display? Can this be done in an intel graphics machine or only on a nvidia or switchable GPU machine?

I'm guessing the same would apply to a W530

My T430 with Intel integrated graphics can do it on Windows 7, so I think the T530 and W530 can do it too. I'm using a dock with the other two external monitors going through DisplayPort.

So I would need to get a dock? The T530 has a VGA and a mini display port, can they both be used in addition to the internal screen or do you need a dock to use all three?

What is the best dock for these T530 / W530s?

No, you you do not have to get a dock if you don't want. I just put that information so you know my set up. You can use the miniDP and the VGA together to get internal + miniDP + VGA for three independent monitors.

Here's the link for the possible configurations that will work for Intel HD 4000 graphics https://www.intel.com/content/www/us/en ... Code=us_en
Here's a link for the possible configurations that will work for ones with NVIDIA graphics https://support.lenovo.com/us/en/solutions/ht037605

As for what's the best dock, I will point you to dr_st's post about the docks in Part 7: Series 3 docks viewtopic.php?f=21&t=123257. What's best for me may not be the best for you and what's best for you may not be the best for me, so I'll let you decide.

Thanks. I got two Series 3 plus docks with USB 3.0 The ones with multiple display output options. Some Lenovo site mentioned that a system with Intel graphics can't use 3 displays but the Intel link you posted says you can. Now I just need to get the proper cables for this (mini display port and / or DVI).

Hi, 4337 or similar docks highly recommended - very cheap and very useful. I believe mine is 4337. It's got one DVI and one display port output. I understand you can link a display port output via an appropriate cable to any of DVI, HDMI, or DP. I believe there may be dock varieties around with 2 dvi outputs and probably with two display ports too. Look around. I believe I read somewhere that there are in total 2 display port lines going via docking connector on *20 and *30 models. Therefore we can expect 2 monitors to work connected to the dock. I'm less sure if you can get a 3rd monitor at the same time.. I would think that the notebook should be able to at least drive it's own built-in display + 2 external ones, but this is my speculation.

I think the version of DP that we have here doesn't allow MST hubs. There is also a display port output on my T520 itself - I'd expect for there to be one on T530/W530 too. But I have no idea if it will work at the same time as those two on the dock
X220, 2 *T520

Nice, I believe that's the 4338. Those should serve you well. Have fun ThinkPadding. I think the key is the wording of "3 displays", so I don't think that three external monitors is possible, but two external + the internal laptop one will get you 3 displays.

Yes, type 4338. More ports than I ever saw but NO ultrabay!

Lenovo must have made an internal change because I received two different PNs. One made in Sep 2012 and the other in Apr 2013. They look identical, but there must have been a reason for the change. I hope there are no issues with the 2012 build docks.

My daily driver is a type 4338 manufactured 12/05 (which I would assume is May 2012). No problems here and I've been using it for ~2.5 years now. I think I only use about 3 of the USB ports at a time - mouse, keyboard, printer. By the way, you can use the USB ports on your laptop at the same time too, so you're getting quite a plethora of USB ports!

Lenovo seems to always have multiple FRU for the same product, don't know why.

Also, I run a 4K monitor and a 1600 x900 monitor in portrait mode, but with the T430 lid closed, so the Intel HD 3000 is capable of high resolution monitors.

The 4337 has 1 Displayport, 1 DVI-D, and 1 VGA.

The 4338 has 2 Displayport, 2 DVI-D, and 1 VGA.

If memory serves me right, the **30 Intel systems support 3 total displays max, but two of them have to share a clock, which means they should be DisplayPort. With 4337 docks you can use any 2 of the 3 ports on the dock, or Dock DP + chassis DP + another port (or internal display). With 4338 you can use both DP on the dock, and the third display can be either dock VGA or laptop DP or internal display.

I think nVidia systems of the **30 generations may be able to give up to 4 displays under certain combinations, but I don't remember the details. The information is available online (I have some links in my T410/X220/T430s survey), but it's sometimes contradicting and confusing.

Just a data point here, I recently bought two 2K monitors (2160x1440) and run them off the display ports on the 4338 dock with no issues. Have the laptop display as a third screen. Running with discrete graphics.

No gaming, no real video watching, mostly for work, but runs great.

That's good news. I got a 2nd identical monitor for her setup, another Dell U2412M, so they can both use DP. I have DP cables, but not the stooopid miniDP to reg DP so I'll still need 2 cables, and then just need to get the T530 set up. I'll use its internal display as the 3rd so she can use the cam that's on it when needed.

For me I'll just stick with the single U2412M on my main setup and a couple WSXGA+ 22" ones on the dining room table test lab setup.

If Dell U2412M is your preferred monitor at the moment, have a look at the Dell U2413F.
Less power, better/more brightness, response, colours and ports (has HDMI).

Really wanted a third one running off the mini-DP, but $$ and space constraints wouldn't allow it. the screen real estate and how close I sit to them makes these perfect though.

I thought if you're using a dock and both DisplayPorts, it doesn't allow you to use the miniDP?

You should be able to use the VGA, miniDP or internal monitor as the 3rd display (4th display if the ThinkPad has nvidia graphics).

I re-read my prior post. I should not need new cables, the Series 3 mini dock plus has two regular size DP ports so those can go to the two U2412Ms and the internal display will be the 3rd. If I wanted to direct connect from the T530 to a DP port, Then I would need a miniDP to reg DP cable.

@RBS,
The U2413 was the successor to the U2412M. It added HDMI but took off the VGA port and all of my ThinkPads have VGA and not HDMI ports. If I bring another monitor in here, she's gonna take a bat to it, and she knows how to use a bat.

The U2413 was more the successor of the U2410 (wide gamut), but yeah - the analog ports were gone. I still have the U2410 and I hope it stays in working condition for a few more years. Excellent monitor.

Didn't the U2410 have component or composite video inputs as well?

Problem with these and many other monitors, is while the screen quality May have improved over the years, the input flexibility has certainly been more limited with each successive iteration. Then there was the change from 16:10 to 16:9, which makes all the later ones that much less desirable. That's why I hunted down a nice used U2412M for the boss lady so she could have identical screens. No more going from 1900x1200 to 1650x1050 when sliding a window to the other monitor. I'm using her old Samsung with my old Acer (both 22" WSXGA+) on mt T61 6463. My U2412M is still in my office with my T61 8898, where I do not think I can fit anything even 1" wider in the structured computer desk. These U2400 series are very nice and durable.

It sure does. Never used them, not even once. But have used both DVI inputs, DisplayPort and HDMI, and probably VGA once or twice as well.

Truth. I started with a Dell P2016 and I liked the rounded corners. So then I hunted for P##16 series with bigger screens for later monitors. The newer P series ones in all black with the 90 degree corners changed the button layout, changed the ports, and is less aesthetically pleasing to me.

You should be able to use the VGA, miniDP or internal monitor as the 3rd display (4th display if the ThinkPad has nvidia graphics).
For what it's worth, on Linux Mint, xrandr shows:

VGA-0 (disconnected)
LVDS-0 (disconnected)
DP-0 (disconnected)
DP-1 (disconnected)
DP-2 (disconnected)
DP-3 (disconnected)
DP-4 (connected)
DP-5 (connected)
LVDS-1 (connected)
VGA-1 (disconnected)

Not sure if those all translate to actual ports being available. I'm assuming the DP 0-5 correspond to 2 DVI's and 2 DPs on back of the docking station, but I'm not sure why two more show up. At least one of them is the mini-DP on the laptop but I'm at a loss where the others are unless they're virtual ones. There's a VGA there as well and one on the laptop, that accounts for both. The LVDS is of course the laptop screen, but again there's two more of each.

I don't remember there being this many when I was using DVI only cables, but I could be wrong.
