The image you see above is a classic shot of John Carmack hard at work programming some integral part of the now legendary game Quake.Most people look at the picture and just see a very focused, famous coder. But look more closely and you realize that display he’s staring at is absolutely huge. Then you realize this is 1995 when LCD monitors are still in their infancy for desktop displays and any flat screen is both small and costs a small fortune.The display Carmack is working with is a very different beast, and by beast we mean this display was absolutely huge. It’s a Silicon Graphics/Integraph InterView 28hd96 color monitor. It’s basically a 28-inch CRT that weighed a back-breaking 45kg (99.5lb). Its dimensions were 49.5 x 69.9 x 62cm and its typical power consumption was 180 watts!So this is just a TV being used as a monitor? No, the 28hd96 was a proper computer monitor that had a few qualities making it very desirable to Carmack. Top of the list was the fact it could handle 1920 x 1080 resolutions, meaning whatever Carmack had under the desk in terms of computing power was probably working flat out to serve such a high resolution image back in ’95.The actual display size was only 25.9 inches, and the brightness maxed out at 100cd/m2. But even so, this monitor would have been the envy of many a programmer (and gamer) back then. The screen real estate must have seemed very excessive to most computer users at the time.I wonder what Carmack uses now? Whatever it is, he could probably have several of them hooked up to a machine each running at 1920 x 1080 and still come nowhere near close to drawing 180 watts.Read more about the display at CEU-Inc.com and thanks to Fabien Sanglard for highlighting it.
