How to find out the HDMI version supported

  • 772

How can I find out which HDMI version the laptop supports, in particular if it is HDMI 1.3?

Full story:

I'm considering acquiring either a Dell U2414H or Dell U2515H/Dell U2715H (or similar) capable of resolutions of respectively 1920x1080 and 2560x1440. This is for an old laptop with an nvidia 9600M GT, which supposedly can handle a resolution of up to 2560x1600.

Since the laptop only comes with VGA and HDMI, I'll be using the HDMI port. It seems that to support the resolution of 2560x1440 of the larger monitor I'd need to have HDMI version 1.3; HDMI 1.2 only supports resolutions of up to 1920x1080.¹ This mean that with HDMI 1.3 I can buy the 27-inch monitor, otherwise I'm better of with the 24-inch one.

¹ I suspect the laptop doesn't support HDMI 1.4 because it got out around the time it was bought. Checked it on wiki.

  1. You cannot probe this information directly, but you can infer it. Below all HDMI versions:

    HDMI version    1               1.1             1.2             1.3             1.4             2
Date released:  9 Dec 2002      20 May 2004     8 Aug 2005      22 Jun 2006     28 May 2009     4 Sep 2013
Max resolution  1920×1200p60    1920×1200p60    1920×1200p60    2560×1600p60    4096×2160p30    4096×2160p60

    So you can be sure you've got 1.3!
