Laptop graphics have always been something of a joke performance wise. Nvidia and AMD do try, but cramming all those millions of transistors into a low-power, compact package just leads to massive expense and an inability to upgrade.

Wouldn't it be perfect if you could simply use a standard external graphics card to power your laptop's 3D graphics?

The good news is that you can. The suitably technical-sounding PE4H is just that; a passive PCI-e x16 to x1 adaptor, which enables you to plug an external graphics card into a laptop's ExpressCard slot. Currently we're only aware of it being available from the Taiwanese firm www.hwtools.net for around $100 including shipping.

We'd like to say it's as simple as that, but this project does have a few sticking points. The first we've already mentioned: a laptop with an ExpressCard slot.

The second is Windows 7, as it handles multiple display drivers far more adeptly than anything else. We're told Windows XP is next best with Vista being least desirable.

Also if your laptop has more than 2GB of memory a 64-bit installation is also required, as otherwise you'll hit the 4GB address space limit hard. The big issue here is that it'll cause the allocation of memory for the graphics card to fail.

Even though the card has its own memory the processor still needs to be able to address it, this address space is added on top of any existing system memory plus any other hardware resources, including the integrated graphics memory space.

The final sticking point is that there are certain laptop models that this simply won't work with or have some serious documented issues. Some of these can be worked around and others cannot, but before you run off and spend your money it's best to check if people have reported issues with your model.

The best two sources for compatibility can be found on the Notebook Review forum and Village Tronic. The former is the best, offering detailed system configuration and how many issues are solved.

The PE4H comes with the adaptor itself, an ExpressCard, data cable, Molex power cable and ATX power switch. Alongside this you'll need a suitable power supply, the adaptor can take a 12 to 15v supply but for higher-end cards you'll need a desktop PSU anyway. Plus for neatness we're going to house it all inside a mini-barebones case.

The walkthrough below details putting together a system. The main thing to be aware of is before plugging the ExpressCard into the laptop, you will need to have Windows fully booted and to have the graphics card powered up. It's important to do this so Windows can recognise and install the correct drivers. If everything goes smoothly you'll have multi-card, multi-monitor system, where there was none before.

This might not be evident but it has happened, check the Display Properties Control Panel to see if the new display is detected and active.

Troubleshooting

In our case we encountered a couple of issues on our Lenovo X200 at this stage, which we can see other people encountering. If the card isn't detected reboot and see how the BIOS handles the new device.

For us booting produced a stream of POST errors complaining about PCI resource allocation problems. A BIOS update later and we had a booting system but one that was running incredibly slowly.

Our next step was to try inserting the card immediately after pressing the power button and that seemed to sort this out. Similarly another trick is to put the laptop to sleep insert the card and power back up. Whatever voodoo cured the problem, once it was up and running we didn't have any further problems and the device could be happily hot swapped. All of these issues are connected to allocation of the PCI address space for the card.

Once it's up and running it just works, albeit within the limitations of a x1 PCI-e system. You may have spotted that the adaptor card offers four PCI-e connections, the obvious question is how do you connect those additional PCI-e lanes?

Most laptops use a mini-PCI-e add-in card for its wireless adaptor, other laptops actually have spare mini-PCI-e ports for 3G modems and the like. If you can locate one of these and add-in one of the HWTool PM3N mini-PCI-e adaptors, then it's possible to upgrade to an x2 system where the performance hit narrows to around 75 percent of the graphic card's full performance.

This, of course, requires a second cable to be trailed from the laptop to the adaptor, as it turns out these are mini HDMI (Type-C) cables, so can be picked up from various sources such as www.lindy.com.

Use something like SiSoft Sandra to see what chipset your laptop has and what devices are attached to them, the Hardware Buses report tool is best. The older ICH6/7M Southbridge can provide up to four PCI-e ports. The newer ICH8/9M and HM55 chipsets can go to six, with the latest HM/QM/QS57 range providing up to eight. You need to use the ports in matched pairs for it to work, so ports one and two or three and four.

DIY desktop graphics for your notebook

We remember getting excited about an Asus prototype called the XG Station a few years back at Computex in Taipei. That device promised to do something similar to this project. It never made it to the UK though, but did pop up in Australia in 2008 before promptly disappearing within a year.

No matter, we'll show you how to hook up your own spare PCI-e graphics card to your laptop. It just takes the right bits of hardware and an ExpressCard equipped laptop. We're even going to look at an easy way to package the whole lot into an external case.

1. The kit you will need to make your adaptor

The catchy named PE4H from www.hwtools.net comes with a x16 PCI-e adaptor, the ExpressCard interface, an ATX power switch, plus the necessary Molex power cable and PCI Express data cable.

2. Grab a passive PCI Express adaptor

The adaptor that takes the PCI Express graphics card is called a passive adaptor, which is actually not doing any processing or routing, it's simply connecting two buses together.

3. Connect the GPU to the ExpressCard

Getting started is easy enough, plug the graphics card into the adaptor and connect the data cable to the first PCI-e port and to the ExpressCard, not forgetting the power cable.

4. Get a PSU powering your graphics card

So you can use a standard PC system power supply for your graphics card an ATX power adaptor is supplied, which will attach to the 20/24-pin power cable of the PSU.

5. Everything hooked up and ready to go

With a basic PCI Express graphics card the set-up looks a little like this (with or without a loop in the cable). At this point you don't want to connect the ExpressCard but you can boot your laptop.

6. Now, power up the pixel pusher

Before you go ahead and connect the ExpressCard to your laptop, you must make sure that the graphics card is powered up, so turn on the ATX switch and power up the PSU.

7. Get in on some ExpressCard action

With your Windows OS laptop up and running along with external graphics card, you can now safely push the ExpressCard into its slot, being careful not to knock over the graphics card in the process!

8. Displays ahoy, as far as the eye can see

If you have a compatible laptop, then after a flicker or two and perhaps a reboot, the laptop should detect the new graphics card and automatically start installing the driver.

9. Control, multimonitor is a go

If everything has worked correctly then you will now have a multimonitor system that you can configure from the Windows Display Control Panel.

10. Put her safe 'n' sound in the mini

To create a neat external box, we're going to cheat a little and just shanghai this rather nice mini barebones box. We won't need the original mobo though we might be able to use the PSU.

11. Compact and decidely bijou

This box has space for two PCI cards, so even a double-width graphics card should easily fit inside the chassis and the PCI-e adaptor sits nicely, where the mobo used to be.

12. Get the power that you really need

It's important to make sure the power supply unit's 12v rail will meet the power supply needs of the card. Check the Wikipedia entry to look up the TDP of your chipset if you're unsure.

13. Get a cable, that is Type C

We're going to route the connecting cable out of the side of the case. To make life easier it'd be best to pick up a longer mini HDMI (Type-C) cable, which is actually what the cable is.

14. Connect up the power button

The ATX PSU is activated by connecting pins 14 and 15 (20-pin) or 16 and 17 (24-pin) together. It's the green wire and any black wire, so you could connect up the case's power switch instead.

15. And this is one I made earlier…

And here she is, our neatly finished solution for getting desktop graphics on your weedy laptop. The mini-case, as it turns out, makes quite a handy monitor stand. Or you can just hide it away.

(δεν διαβασα το θεμα τις εικονες ειδα) ποσο κοστιζει αυτο?

[grouspen]

πολύ μπλέξιμο. αναμονή μέχρι να γίνει mainstream το thunderbolt στα laptop και να φτιάξουν κατάλληλους drivers για κάρτες να τρέχουν από εξωτερικές θήκες και θα γίνουν πολύ πιο εύκολα τα πράγματα (για κάποιον που θέλει να κάνει κάτι τέτοιο)

1000 φορές σταθερός αλλά άμα χρειάζεσαι φορητότητα ίσως να είναι καλό

Coming soon: an external video card near you? As video cards become bigger and more power-hungry, could they escape the …

by Jeremy Reimer - Aug 2 2006, 11:01pm GTBDT

 

Internal video cards have been around as long as the PC—IBM's original 1981 model had no graphics at all, until you added the IBM Color Graphics Adapter (CGA) and reveled in its 320 by 200 resolution modes in all four glorious available colors. More recently, gaming enthusiasts have driven the market for expensive, power-hungry 3D graphics cards from ATI and NVIDIA, some of them requiring huge cooling solutions, additional power connectors, and even taking up the space normally occupied by two card slots.

Now, both companies are toying with graphics solutions that go to the next level. Some cards are now available, like Asus' EAX1800XT, that offer an external 80 Watt power supply to ensure that the computer's own power supply doesn't get overloaded. The next logical step would be to remove the graphics card from the computer completely, and put it in an external box.

Sound crazy? NVIDIA has just released a monster external graphics solution for people who have exceedingly high demands for pushing pixels. The Quadro Plex 1000 is a set of graphics processors enclosed in its own box, capable of rendering 80 billion pixels per second and powering multiple monitors with a combined resolution of up to 148 million pixels. It doesn't come cheap: prices start at $17,500, and it is intended primarily as a networked rendering solution. It requires one or two free PCIe slots (yes, you can buy two and run them in SLI mode) to connect it to your computer.

The NVIDIA Quadro Plex 1000

A more consumer-friendly external product might be useful for people with laptops or desktops without a PCIe slot. An external graphics card might be just the solution for someone wanting to play the latest and greatest PC games without purchasing a new computer. Some companies, such as Matrox, already provide external devices such as the TripleHead2Go that expand a laptop's display over multiple monitors. These solutions typically use the computer's existing graphics card and GPU, however.

A completely external graphics card might be a neat upgrade for laptop users, but there are some technical hurdles that have to be overcome first. The primary issue is that of bandwidth. USB 2.0 provides 60 MB per second maximum throughput, whereas today's PCI Express slots have a maximum possible bandwidth of 8 GB per second when operating in full-duplex mode. Such high bandwidth is needed to drive today's fast-action 3D games.

However, with the merging of ATI and AMD, there is a possibility of the new company developing a high-speed external video connector with enough bandwidth to make this feasible. While rumors are flying around the 'Net about ATI's new graphics cards based on the R600 core being external, these stories are most likely misinterpreting the need for the next-generation cards to have external power supplies. Unfortunately for laptop owners, a truly external gaming graphics card is not yet on the horizon.

NVidia Ion – Strong External Graphic Card for NetBooks

by Ken Xu in Graphic Card

As the matter of fact, Netbook have the benefits in size and portability while completely suck in graphic performances. That’s why nVidia invented ION, an external Graphic card for netbook with power as strong as a high-end performer graphic card.

NVidia Ion - New External Graphic Card for Netbook

NVidia Ion platform is actually a GeForce 9400m GPU. With this type of external graphical power addons, a netbook now can perform a much better task such as watch High Definition video or playing high end games.

Inside view of NVidia Ion

NVidia Ion will allow a netbook to run on Vista or even the Pre-launch Windows 7 while generating lesser heat with the same power consumption. But this type of performance addons needs you to add an additional $50 to the overall price before you can enjoy the benefits.

Sony Vaio 13 ιντσών με εξωτερική κάρτα γραφικών!

by Δημήτρης Θωμαδάκης

Computers, News | Δημοσιευμένο στις 28 Ιουν 2011

Υποδεχτείτε το νέο Sony Vaio Z21V9E με πάχος μόλις 17 χιλιοστά και βάρος 1,2 κιλά. Έχει επεξεργαστή Intel Core i7 2620M στα 2,7 GHz, 8 GB μνήμη DDR3 στα 1333 MHz, σκληρό δίσκο SSD 256 MB, οθόνη 13 ιντσών και υποσύστημα γραφικών Intel GMA HD 3000. Μέχρι εδώ, καλά. Παρακάτω όμως… έρχονται τα καλύτερα.

Επειδή σε κάθε περίπτωση το gaming είναι ένα σημαντικό κριτήριο στην επιλογή laptop, η Sony βρήκε τη λύση για να διατηρήσει τη φορητότητα του νέου της laptop, και να ικανοποιήσει τους gamers χρήστες ταυτόχρονα. Η απάντηση βρίσκεται σε μία εξωτερική κάρτα γραφικών. Συγκεκριμένα, πρόκειται για ένα dock, το οποίο περιλαμβάνει ένα GPU AMD Radeon HD 6650M με 1 GB DDR3 video RAM, θύρες VGA και HDMI. Στο ίδιο dock περιλαμβάνονται θύρες USB όπως και ένα slim Bluray drive.

Βέβαια για να λέμε τα πράγματα ως έχουν, δεν είναι η πρώτη φορά που βλέπουμε μία τέτοια συσκευή, καθώς είχε προηγηθεί το Asus XG Station, που κυκλοφόρησε το 2008, αλλά δυστυχώς μόνο στην Αυστραλία. Σε κάθε περίπτωση, το νέο Vaio αναμένεται να κυκλοφορήσει στα τέλη Ιουλίου, και θα έχει σίγουρα ενδιαφέρον να δούμε τι είδους υποδοχή θα του επιφυλάξουν οι υποψήφιοι αγοραστές laptop.
