The simple test of holding down both shift keys and typing "The Quick Brown Fox Jumps Over The Lazy Dog" is not much of a test as it throws false positives that many keyboards will pass. Below is a link to some free testing SW that is more rigorous.

Saw this on OCN, My results with a Razer Lycosa:

My keyboard seems to be unable to type space while holding down both shift keys. I don't know why you would ever need that though.

I don't get it, how do you test?

I'm confused as well lol

My G510 doesn't like to space but it got almost every letter haha

Also Moovlin, what are you quoting? On the page you linked it says:

The absolute worst test is the "Hold Two Shift Keys Down and type the quick brown fox jumps over the lazy dog" - this pangram gives false positives - many laptop and Microsoft/Logitech keyboards pass this test.

Same thing as CentrallyProcessed from a Gateway keyboard that came with a prebuilt.

this is a really bad test, as it does not test full NKRO. it all depends on how the keyboard matrix is wired. the link that geekhack suggested in there NKRO topic works a lot better.

anyways: THE QUICK BROWN FOX JUMPS OVER THE LAZY DOG,

also, NKRO while using USB is a lie. As USB only supports 6 characters at the time. PS/2 supports "real" NKRO though.

my keyboard is a das keyboard professional S btw.

this works well enough i think: https://www.microsoft.com/appliedsciences/content/projects/MultiKeyDisplay.aspx

It seems the "x" is the only key it doesn't like.

I know, I read the article it says to then compare it to the applications results.

How do you test NKRO then? Is there an easy test to do, my K60 seems to register everything. :/

The app in the quote.
