Citrix: Image Quality Comparison: Local vs. HDX vs. Blast

Talk of VMware’s Horizon View 7.3 release prompted me to take a closer look at the latest offering of their display remoting protocol, Blast. I’ve used earlier versions of Blast and found it to be very resource-hungry, especially when it comes to network bandwidth. Granted, if you spend most of your time on a LAN, bandwidth is probably not your main concern, but the thing that really stood out to me was image quality: after 15 minutes or so, I had to stop using the desktop because my head started to hurt!

It’s clear that Blast was and is still largely based on the well-established and popular H.264 codec. As video codecs go, H.264 is hard to beat. That’s why Citrix uses it for video content, as well. But as an everyday desktop remoting protocol, it really falls short of the most basic tenet of desktop remoting: image quality.

To illustrate this point, I’ve put together a simple coloured spreadsheet in Excel and compared — using out-of-the-box settings on a LAN — how HDX and Blast look vs. local:

You’d be hard-pressed to see any difference between Local and HDX. Blast, on the other hand, is very different. Here’s a close-up showing some key differences between HDX and Blast:
