Wither the poor CRT

Posted by Trixter on July 17, 2006

My wonderful, trusty, always perfect six-year-old Sony G400 19″ Trinitron CRT monitor expired this evening. (I’m typing this on the company laptop.) Which leads to a very interesting problem: How to buy a new CRT?

The question isn’t really a serious one, since you can still order CRTs via the web. But the number of models produced, along with their quality level, is diminishing almost down to nil because of LCDs. I haven’t bought a monitor since the G400, and in those six years the landscape has completely turned 180 degrees: LCDs are now the preferred monitor for new computer purchases. There are new models out all the time, their prices are dropping while sizes are increasing, and they have greatly reduced energy consumption and radiation levels.

My problem is that, for my needs, they all suck.

There is no LCD that can do what I need out of a display device. Before you scream “gaming!”, I am already aware that response times have gone down to 16ms and below, making a true 60Hz refresh rate possible. But I have two very basic needs, one old and one new, that LCDs cannot accomplish today — and, in the case of one need, will never be able to accomplish:

  1. Color depth: I need full 24-bit color out of my display device because of the video work I do (yes, I also have an external broadcast monitor, but I like to work in resolutions greater than 720×576, thanks), and LCDs today are capable of about 18-bit (cheap) to 20-bit (expensive) color output. If you don’t believe me, create some (non-dithered!) gradients in Photoshop of red, green, blue, and luma (black to white) of levels 0-16 and 236-255. Make those gradients go all the way across the screen. You should be able to pick out each level, right? Well, try. You’ll see that some of them are getting posturized.
  2. Multiple resolutions: LCDs have a fixed resolution. If you want to work in a different res than what the LCD provides — like, oh, I don’t know, lowres oldskool gaming — you have to settle for some stretching of individual pixels. No matter how good the algorithm, it looks like ass.

My CRT hunt begins. If you know of any decent, professional 19″ or 21″ trinitron CRTs for sale under $400, lead me to them :-)

March 3rd 2009 Edit:  I was able to repair my Sony G400, but it sits under my desk unused as I have to use a widescreen LCD for my MindCandy 3 HD work.  However, this isn’t terrible; while the LCD has a few issues that bother me, it is indeed 24-bit color (and cost $$$ appropriately to get that).

Also, here are some PNG files for Brolin who wanted to see what the difference was between a good LCD and cheap one:

Nerd

Posted by Trixter on June 12, 2006

I am pretty proud of myself when it comes to the TV situation in our house: I own a ReplayTV instead of a TiVo, so for over two years I've been able to stream shows to any PC in the house (wirelessly), can dump shows to DVD, and generally hold more programming than I have time to watch. (This functionality was only recently duplicated by an unsanctioned TiVo hack, so TiVo owners, I fart in your general direction.) I'm even proud of myself for finding a free MPEG-2 player (VLC), with not only proper 60Hz progressive display of interlaced material, but also a mod to automatically skip commercials using the ReplayTV's built-in commercial-skip metadata. So, when it comes to watching DVR shows, I'd like to think I'm pretty bad-ass.

Last night I was settling down in bed to watch shows before I hit the sack, and I pulled up DVArchive and checked the list of shows I had downloaded and waiting for me:

  • Daria
  • Doctor Who
  • Miami Vice
  • Saturday Night Live
  • The Outer Limits

All I could think was, "My god! I am such a flaming nerd!"

Beginnings and Endings

Posted by Trixter on May 25, 2006

There is a great quote from David Cain that explains the birth of most of the underground electronic art scenes, like the demoscene, tracker scene, or ANSI/ASCII art scene: "It is the point where the desires of the creator are greater than the technology which is available." An expanded citing of this quote also reveals how such scenes can self-destruct, and helps illustrate why I dropped out of the demoscene in 1997. It goes:

There comes a moment where the technology gets closer and closer to the imagination and creativity of the writer, and in the end, if you're not careful, it overtakes. And suddenly, serendipity — which before was from your own sweat and blood — comes by saying "If I press one of these 397 buttons, maybe I'll get something out of it." Now, at that moment, the machinery is driving the creativity, and the creativity is (no longer) driving the machinery. — David Cain, BBC Radiophonic composer from 1967-1973

Of course, the challenge is for the end of one age to become the beginning of another.

Computing Myth #2: Broadband only works with a new computer

Posted by Trixter on February 2, 2006

While this isn’t technically true, I can definitely see how this myth was formed. My father ran on a 486/66 with a modem from 1995-2001. In 2001 he got cable modem broadband, but his 486/66 was so slow that it couldn’t process complex web pages much quicker than it already was, so he saw no actual speed benefit. So he went back to the modem, at which point I almost lost it (“How can you want to go slower?!”)

Later he upgraded to a Pentium 3 @ 450MHz, and could finally perceive the modem as a bottleneck.

Ironically, two years later, I did the same type of thing (downgrade powerful hardware): Through a telephone conversation mix-up, I agreed to reserve and purchase a Yamaha snowblower — and when I got there, I had reserved the wrong one. What I thought was going to be a $600 18- or 24-inch blower was actually a $1300 36-inch semi-industrial model. I was coerced into buying it because renigging on the reservation meant I would be charged $50 because these things were in demand in the middle of winter. So I bought it to avoid the fee, took it home, opened the box, took one look at it and knew I could never use it for my tiny driveway without being embarrased (it wouldn’t even fit in my garage with both cars), and proceeded to box it up and return it. On that day, a snowstorm began. As I’m returning this monster snowblower, I get a goofy look from the kid helping me; when I inquire, he says, “I’ve just never seen anyone return a snowblower in the middle of a snow storm!”.

Computing Myth #1: Software cannot damage hardware

Posted by Trixter on February 2, 2006

Oh yes it can. Here’s a story for you: In my teens, I had a friend who got the IBM 5155 (the Portable Computer — you know, the heavy luggable one with the monochrome CRT monitor inside it) from a Computerland. He was screwing around with POKE in BASIC and POKE’d a value somewhere into CGA-land, saw some pretty squiggles for about 3 seconds, then poof and we smell the familiar smell of ozone. We went back to Computerland, but they told him that there was no way that software could have damaged hardware and they weren’t going to repair it (thinking that he had dropped it or something). So my friend, with salesman watching with one eye from across the room, walks over to another one on display, takes the diskette out, boots into BASIC, writes a 1-line program, and poof, ozone, and no more monitor. Salesman didn’t quite know what had happened, so my friend walked over to another one on display and does it again, but steps aside so that the salesman can see it this time.

Let me tell you, I’ve never seen an overweight, balding, 50+yr old move so fast. He sprang like a gazelle toward us and for a second I thought I was going to get the crap beaten out of me. Thankfully, all he did was yell, about how we were going to have to pay for that, etc. This got the attention of the manager, who came out and said they’d honor the warranty and fix his machine if the kid would stop blowing up all the IBM 5155 monitors in the store.

Inanimate Empathy

Posted by Trixter on January 28, 2006

My very first digital camera broke today: A Casio QV-3000EX, purchased in early 2001. The second 3-megapixel camera ever on the market, it took brilliant outdoor shots in automatic mode, and took generally stellar pictures if you knew how to use its manual settings (f-stop, apeture, shutter speed, and more). See for yourself; here are some shots taken in full automatic mode:

Lee and Alexis HaskellJohn, Sam, and Max Leonard

I took the time to learn a few things about amateur photography and how to use some of the manual settings, and it took some the best 3MP shots I’ve ever done:

Tree In FogChicago At Dusk1-minute chickKite in Sky

I loved this camera. I mean, I really got to know everything about it, what its strengths were, weaknesses, and more. when I put it in the trash, I felt like I was burying a friend.

And right now I’m thinking, why? Why am I personifying this camera like it’s a friend that I’ve lost? Why do we, as a society, project empathy onto inanimate objects like they’re people? Several times while writing this post, I wanted to use terms like “my camera gave up the ghost” or “it finally died”. I felt strongly enough about my first computer that I wrote fiction from its point of view. People call ships and planes “old girl” or even actual female pronouns like “old bessy” or “nellie”. It’s fascinating, and probably answered in a psychology book somewhere.

I’m going to replace it with a used model, probably off of ebay. I wonder if it will mean as much to me as the original did.
