Q: Can ViDock be used on Server PC, SFF ( Small Form Factor ) or All-in-One PC?

A: Yes. With ViDock together with ViCard 1 (PCIe to ExpressCard adapter), you can add an external PCIe card or graphics card in ViDock to your PC.

Q: Does ViDock support non-graphics card?

A: Yes. ViDock G3 supports any PCIe card up to two 6 pin power connectors.

Q: What is ViDock G3 Overdrive?

A: ViDock G3 Overdrive is the upgrade to ViDock G3 (ViDock 3, ViDock 4, ViDock 4 Plus). The Overdrive Product line delivers approximately 40 % more power, reducing compatibility problems with graphics card which draw more power than specs allowed.

Q: Does ViDock work with USB to ExpressCard adapters?

A: A USB to ExpressCard adapter will only work with ExpressCard devices that use the USB portion of the ExpressCard interface. Since ViDock, and many other ExpressCard devices, use the PCIe bus in the ExpressCard interface, such an adapter will NOT work with ViDock.

By the way, USB slot is much slower than ExpressCard. In order to connect graphics card you really want the speed that ExpressCard is providing to enjoy a much faster graphics card than built in.

Q: Is ViDock compatible with MacBook Pro?

ViDock adapt PCIe cards to an ExpressCard slot. They work with any compliant ExpressCard slot, including the slot in the MacBook Pro. PCIe cards that do not require a large PCIe memory window, such as professional video and audio editing cards (BMD, AJA) and storage controllers, will work with MacBook Pro and ViDock.

Before, only MacBook Pro generations 1, 2, and 4 support graphics cards on the PCIe bus provided in its ExpressCard slot. Nowadays, we have many customers who got it to work on Mac OS 10.7 (Lion) as well as Boot Camp Windows 7 on the other generations of MacBook Pro when they run ViDock on Windows 7.

In general the use of nVidia GTX Fermi or the latest cards is preferred as they cause less trouble than ATI in terms of Error 12 and driver conflict, and nVidia Optimus driver delivers higher performance on limited host connection bandwidth, as such is the case when using ExpressCard.

Q: XX Graphics Card is Minimum 500 Watt, Can ViDock 4 Plus handle this card?

A: The 500W is the system requirements of the card you mentioned below, which is not the power provided to the Graphics card by ViDock. If you study the picture of the card you propose, you can see there are two 6-pin Power Connectors at the bottom, thus the Maximum power consumed by this graphics card should below 225W. In this case, ViDock 4 Plus can handle it.

Q: How much performance will be lost by running graphics cards at PCIe x1?

A: Since the laptop's PCIe x16 bus is not available outside of the laptop enclosure, performance comparisons between PCIe x16 and PCIe x1 do not make sense. The intent of ViDock is to upgrade a laptop's graphics performance. So, the correct comparison is between a PCIe graphics card's operation using PCIe x1 to a laptop's internal graphics engine. In almost all cases, a desktop PCIe graphics card running at PCI x1 will outperform a laptop's internal graphics many times over. Today's graphics engines perform an overwhelming amount of processing on their GPU and do not rely on the system's CPU. This means that, in many applications, overall graphics performance does not have a large relationship with the bandwidth of the PCIe bus.

In one case, one of our customers could only run Starcraft II at 2fps on his laptop. Using a ViDock with an desktop PCIe graphics card, he was running at 62fps which is nearly 30x improvement.

Q: Does ViDock support PCIe 2.0? Does ViDock support ExpressCard 2.0?

ViDock uses the PCIe bus and USB 2.0 bus in the ExpressCard interface. In ExpressCard 2.0, the PCIe bus and USB 2.0 bus connections do not change and the PCIe bus is allowed to operate at 5.0 Gbps. ViDock has been designed and tested to use the full bandwidth of the PCIe bus and USB 2.0 bus that are in the ExpressCard slot. The bus transfer rate will be determined by the laptop that hosts the ExpressCard slot and the PCIe graphics card that is installed in ViDock. So, ViDock is already capable of supporting ExpressCard 2.0.

Q: Do you plan on launching a ViDock that supports PCIe x16?

Laptop PCs do not have an external connection for PCIe x16. Without such access, a PCIe x16 expansion device could not be used with laptop PCs.Therefore we have no future plans for such a product.

Q: Is the only way to output video from the ViDock is by using an external display? Is there a method to use my laptop's native display instead? // do I have to buy a screen or can I use the display on my laptop?

A: In general ViDock needs to connect to the external display, the video can not be sent back to the internal display of the laptop. However, if your notebook has an internal intel HD, intel 3000hd, or intel 4500mhd, and you have nVidia fermi/kepler card in ViDock, with nVidia Optimus driver it allows you to use your laptop internal display.

Or, if you want to use the GPU for GPU computing using CUDA or OpenCL, you do not need the external display.

Q:Will ViDock support quad monitor cards such as the ATI FirePro 2450, 2450x1, and 2460?

A: The ATI Fire Pro 2400 series graphics cards are half length PCI Express cards that consume very little power. They are ideal for ViDock 3.

ViDock 3 provides the PCIe x1 bus from an ExpressCard slot to a PCIe card slot in the ViDock 3 housing. This PCIe slot is, physically, a PCIe x16 slot connector. PCIe cards that are x4, x8, and x16 will notice that they are connected to a x1 slot operate at this bus width.

Operating four monitors with the ATI FirePro 2450 in PCIe x1 mode will provide far greater graphics performance than operating two displays from a laptop's internal graphics and two more on DisplayLink devices using USB ports - the only practical alternative in the case of a laptop PC.

Q: I don't have a Paypal Account, how could I pay by credit card?

A: PayPal processes our credit card transactions. You do not need a PayPal account, PayPal's service will only be used to process the credit card payment for us. We do not use any other service provider to process our customer's credit card payments.

Q: What is your return policy?

A: Return Policy

Q: ViDock connect with only got 2.5gbps bandwidth and normally the bandwidth of PCI-E x16 on desktop is 128gbps. Is the ViDock working with performance reduce like working on PCI-E x1 ?

A: the PCIE lane x1 does provide less bandwidth, than a PCI lane at x16; however, graphics cards do most of their processing on the Graphic Processing Unit, which means it doesn't require large amounts of raw bandwidth to send data back and forth from computer to Graphics Card. There would be little, if at all, performance difference between the two lanes.

Q: I'm programmer. I need to big resolution as 2560 X1600 on monitor like 30". So is there any product can display like that resolution?

A: I recommend that you use a ViDock 3 with a low end desktop graphics card like a ATI HD5550, a 9500GT, or equivalent that supports your resolution.

Q: Will the ViDock work with any notebook that has a ExpressCard slot?

A: ViDock will work with any ExpressCard slot. It brings the PICe bus from the ExpressCard slot to a PCIe card slot and has been tested at 2.5GB/s and 5.0GB/s to assure that it meets first and second generation PCIe and ExpressCard specifications.

That said, some laptop PCs put limitations on the PCIe devices that they will support on the PCIe bus in the ExpressCard slot. Specifically, PCIe graphics cards require a 256MB window in the PCI memory address space which, in nearly all cases, exists in the memory map. However, there are laptop PCs that only allocate a portion of the available memory space to PCIe devices. This may have to do with boot time, attempting to set aside more memory space for system memory, simplifying the resource allocation algorithm, or other reasons. This results in an error notice from the operating system that there is not enough resources for the device (Code 12). Recently it is reported using nVidia Fermi or latest card, it fixes this problem (Code 12) on many of notebooks. Also you could open a ticket @ (external link) to check if any compatibility report for your notebook model.

Q: how does the ViDock connect to the laptop?

A: ViDock uses the ExpressCard slot to access PCI Express and USB buses in laptop PCs.
For more information on the ExpressCard slot see (external link) .

Q: Do I need to install any software for ViDock?

A: ViDock does not require software. The product itself does not contain a device that your laptop will recognize. You will however, need to install software for the PCIe card that you install in your ViDock.

Q: How can I find out if my notebook has the ExpressCard slot?

A: You can check it in the full specifications of your notebook. Or, you can follow these to check it out:
1) Take out the cover from the slot if you find it. See picture for reference from the link: (external link)

2) Check the size and shape. Both ExpressCard/34 or 54 (NOT CardBus PC Card) are OK. See picture from the link: (external link),r:2,s:0,i:130

Q: Can ViDock be used with PCI Express 3.0 card?

A: Definitely yes! PCIe3.0 Cards are the new generation of graphics cards. As with every new generation Graphics card they offer more "bang for the buck". Meaning for the same money you spend the newer generation card will deliver more performance than the old generation of cards. In short, we highly encourage the use of PCIe 3.0 Cards with ViDock.

Q: Could you ensure that your ViDock will definitely works with my graphics card/laptop?

A: ViDock is compatible with any laptop that has an Expresscard slot. Any compatibility problems are the result of a laptop and PCIe card in ViDock not being compatible with each other. That is the truth.

You could open a ticket @ Support Center (external link) to check if any compatibility report for your notebook model. In case there is a compatibility problem, we can assist you. In most cases we can resolve such trouble. In the rare event that we can not, you could return your ViDock and we will reimburse you the money.
