Thunderbolt vs Mini Display Port confusion

Hello There,

 

I just got a new W540 with Thunderbolt

My goal is to run two identical LCD monitors (1920 x 1080)

I have 3 locations with dual monitors, but can't justify 3 docking stations

 

So I am having trouble finding answers to...

 

1) can I use a splitter to run two monitors off the single Thunderbolt port ? (What Type ?)

 

2) Will any old splitter do ?   (Is apple MDP stuff compatible ?)

   - More of a hub, and all about driver availability

 

3) My monitors have VGA and HDMI inputs only   - Do I really need display port compatable monitors ?

  - A DP hub & 2 converters (DP to HDMI or VGA)  + 2 old monitors ($150.00 dollar solution)

  - One Monitor with dual DP ports - or 1 port &  hub & converter (DP to HDMI))

   - A hub that splits the DP into two (or more) HDMI / VGA

   - Two extreamly expensive Thunderbolt monitors 

 

4) Is it possible to "Thunder split" so that I could run one HDMI to Customer's TV , and other to one of my  LCD's ?

   - Yes

 

5) What sort of resolution and quality could be expected ?

 

    ThunderBolt 2 is designed to handle 4K Video - (2 x 1080p is light duty)

     From  NVIDIA Quadro K1000M Specs...

6) Do I have Tjhunderbolt 1.* or 2 ?
    Only Lenovo knows

 

Thanks for the help !

Re: Thunderbolt vs Mini Display Port confusion

I am curious about this too, as well as the maximum resolution from the Thuderport port, with no docking station.

Hello There,

 

Check this out Belkin Thunderbolt express - It does splt, and is a "dock" (So Thunderbolt can deliver !)

The idea of a single cable is much more attractive than a clunky dock ?

Thunderbolt vs Mini Display Port vs Display Port ?

So If I understand this correctly,

I could have two monitors (one must be Thunderboltish) 

resolutions are not an issue (what about monitors of various resolutions ?)

 

I think the Belkin solution might allow you to keep an external hardrive plugged into an "always on" USB port, and act as a file server for the network ?      Will The Lenovo Docks do that ?

Just a note that all of that thunderbolt equipment is very expensive, especially the monitors. If you do use DisplayPort monitors (typically more expensive than VGA/DVI/HDMI because they tend to be professional monitors, although not even close to the price of TB), though, you can daisy chain them. One cable from PC to monitor 1, and one cable from monitor 1 to monitor 2 (that can be always plugged in).

Re: Thunderbolt vs Mini Display Port confusion

Thanks Shawn,

 

I found these for about $400 - I could not find a Lenovo 27" monitor with DisplayPort  ? (or at least website couldn't)

 

But I am confused.  If you check the specs, It shows these as having USB port's, and I thought no data went over Display Port   ?

Just for absolute clarity Smiley Happy.

 

You said "One cable from PC to monitor 1, and one cable from monitor 1 to monitor 2"

 

    PC to monitor cable - would be a Display Port Cable, connected to the Thunderbolt port on Thinkpad - Yes ? 

 

    The cable from monitor 1 to 2...   Does this mean monitor 1 has to have two Display Port  ports ?

Correct. Mini DP to DP for the computer, and DP to DP for the monitors. You are also correct in that the monitors need two DP ports in order to daisy chain. Here is an article with more information.

Re: Thunderbolt vs Mini Display Port confusion

Another note... It is possible to buy a DisplayPort Hub for around $100-$150 and then connect cheaper DP monitors that do not have the DP out port, although I have never done this before and cannot verify that it actually works.

Re: Thunderbolt vs Mini Display Port confusion

Ok, So at leat one monitor would require Dual ports, might I be able to put a DP to HDMI converter on the end of  monitor one's output ?

 

Sorry if this sounds like an Abbot and Costello routine, but I went with Lenovo, whereas  the Dell M4800 can attach two dual oldstyle monitors right out of the box...  I might be in trouble !  Thanks for the input !

Not sure about DP to HDMI with daisy chaining.

The W540 can also connect to two independent monitors with the VGA and DP ports, although you would have to settle for VGA quality on one.
