Hey did you ever figure this out? I am now in the same situation and Samsung isn't helping at all. It would appear we should have gotten the HAS (height adjustable stand) that will allow it to pivot from landscape to portrait. SamsungParts.com has one for a 22" monitor but I'm not sure if will also fit the 2494HM and it's $65. Please let me know if you found a stand.
I recently just bought a Samsung 2494HM HD monitor and after receiving it, I found out my screen does not have the stand that tilts my screen or make it vertical. When I buy it, I bought it specifically for that function. When I check online, everyone's 2494HM has a 4 way adjustable stand. Does the monitor suppose to get that stand when I buy it, or its a supplement stand that I need to buy? If so where can I buy it? I tried to search it on samsungparts.com but it only sells the stand that my monitor came with. Where can I get the 4 way adjustable stand for my 2494HM? Thanks!
