CF-19mk5 Maximum resolution external display

I search the manuals, spec sheets and NBR, but I can't find anywhere what the maximum resolution is for a CF-19A (intel i5 2520m with the HD Graphics 3000).
Does anybody know where to find that?

I'm looking for an external display and would like to use it at it's native resolution.

 

External video support up to 1280 x 1024 at 16.7 million colors

But my MK3 shows 1366x800 (or something like that) on 1920x1080 monitor. So it's better to try it

 

I really don't understand why there is this artificial limitation. The VGA port should have no problem outputting 1920x1080, and even the GMA950 in the older core duo toughbooks supports 2048x1536 at 75hz.

 

It's VGA port limitation in fact.
It's also too expensive to use good quality DAC for this "optional" port.
2048x1536... theoretically possible, but picture visual quality will be awful.
Why Panasonic doesn't use HDMI/Display Port even in newest (Ivy bridge) model? That is more interesting question

 

There is a way to get HDMI etc in your Toughbook
Look at this adapter
You will need this adapter, ATX power supply, PCI-E x16 graphics card with all video outputs you need
It's not a mobile solution, but it works

 

Could be, but Panasonic seems to artificially limit the resolution quite low, maybe to be on the safe side. The VGA port of my Mk. 2 has no problem with a 1920x1200 screen, once you have tricked around that limit. I cannot see any quality difference to using the same screen via DVI on another computer.

 

For my CF-19/CF-30 I have a ASUS XG Station. Just wish they would of kept making them. It still has the 8800 in it, looking at upgrading here before long. I think Vi-dock is about the only main stream maker left. I have seen several prototypes out though based on newer tech. Doing pretty much the same thing but using the newer thunderbolt socket and not the express card slot.

This is the DIY version like the one in the ebay link above. You can go through the express card slot or the M-pcie slot with the DIY version.


(one reason I still hang onto a older single core thinkpad I have is because of the dock. The larger docks will take a external graphics card. 300w power supply in them too. But they are limited onto a few cards, you can expand your options by using a flexible riser card.)

 

Thanks for all the quick responses.
'm off looking for a native 1280x1024 IPS display. But a quick look didn't make them really easy to find.
I now have to choose between a desktop port replicator and a docking station that can be used in a car as well. The first is a lot cheaper, the second can be a lot more versatile. I have vague plans to mount it in a van/camper (but the camper is still vapor...)

 

Just one other question. Are there external (li-ion) batteries that can be used with a CF-19. It doesn't need to be permenant attached, I just need sometimes about 16-20 hours of battery life in total. I know I could order a second battery and a special holder for it, together with another charger, but that is quite a costly option. €130 for the battery, €151 for the battery holder, and €58 for the AC charger. And then I need to add 19% for vat and €10 for shipping.
All in all a great price of €403,41. It must be possible to do it cheaper and still easy/convenient?

I haven't used either before but it can give you something to search for. I know I have seen external battery packs like these even larger than these are.

 

Thanks Ador, it helps indeed. I think I'm looking for something that holds 60-80Wh of power, so the second one is indeed more than powerfull enough. Even if that is a theoretical capacity (it states having 125Wh) because often the no-brand batteries are quite a bit overrated. ( I have some 2700mAh AA rechargable batteries that last quite a bit shorter than 1800mAh Varta's. So either one of them has been a bit creative with the truth).

 

Alecgold, just buy 1-3 spare original batteries. These ones are good, for example
And CF-VCBTB1W charger (USD 40-50 shipped)

 

That's much better priced indeed! (now why can't the 19 be hot-swappable like the CF-U1 ) I'll have a look into that as well (considering shipping cost, taxes and customs cost).
But these are used batteries, so you have no idea what the remaining mAh is? But at 1/3th of the price...

Edit: I remember something better, I have the CF-LND8024FD 12-32Vdc charger, so I can always charge a battery in the boot of my car when I'm on the go. That way I'll always have one charged battery with me when traveling by car.
For walking/backpacking use I might just need to find/make a nice pouch to protect the contacts of the battery.
One day I want to have a large, ~240 W solar panel on top of my vehicle that is able to charge my laptop/battery without the need of the engine running to charge!

 

They usually have ~90-95% capacity. More than enough.
Never bought new batteries for Toughbooks because of their price
Shipping is free for this item. Taxes... You can ask seller to mark it "USD 30, used batteries for parts" and no taxes or customs

p.s. buy only original batteries - they are immortal

 

I don't have any CF-19 batteries. I am still on my used CF-18 batteries. Remember you can use the 18 batteries on the 19, just not vice versa. Yes the original batteries are the best. I can still get 2 hrs out of my CF-28 battery with the screen light turned down.

 

Remember CF-18 batteries (even orange CF-VZSU30BU) has less real capacity (Whr) than CF-19's battery. Also, CF-19 batteries are newer (date of manufacture).
So it's much better to use CF-19's batteries in CF-19 )

 

Barr, I bought the batteries you pointed me at! Two of them. It might take weeks for them to arrive, but that is no problem for me! I now spend $103 for two, and 3 dealer ones would have costed me €305!
Thanks a lot for pointing me at those. I'm really curious how they will do!

Do you also have a trusted seller for the battery charger?
