lcd aquired

I’ve aquired my lcd monitor. It’s a Samsung 150mp, at mac’s recommendation. Should make things a lot simpler, having direct inputs for many different video types directly, instead of having to use a PC to do the format swapping. Having a remote and picture-in-picture are cool bonuses too.

Next step: lenses and lighting.

  1. hah, stupid dave: direct inputs directly. Way to be.

  2. Sweeeet. Now I’m jealous of the deal you got…so quickly, too! I guess the only thing you don’t have on there is component video, but many devices that offer component out also can do VGA. Especially a media center PC.

    One thing I hated to do was actually take apart the display. It’s pretty awesome as-is, for the price. Also, the eBay ad mentions the possibility of a blue dead pixel. I had a different LCD before the 150MP, and it had one blue dead pixel (and a 100-pixel swath of white due to my negligence). The dead pixel was completely unnoticeable, you might be able to find it if the scene was all one color.

    You’ll have more trouble with dust and finger smudges, they really show up. Build this thing in a clean environment and don’t touch any surfaces, and seal the box except for a filtered fan intake and output.

    For lenses, Lumenlab.com had the best deal I could find, great quality. For lighting, I scrounged eBay, tried a 10000K bulb but went to a 6500K bulb because 10000K is way too blue…reds were a dark purple.

  3. My plan is to wear dustless latex gloves while I’m handling LCDs or lenses. I purchased a kit that someone had for sale on the lumenlabs site with all the lenses, wiring, etc. It comes with a 5200K bulb, which I think will be a good color for what I’m looking for.

    I feel very blessed to have found that monitor so quickly too. It’s going to be hard to strip it. (:

    Thanks for the advice on that one Mac. I’d been looking for something similar, but having a specific monitor to hunt for makes it a lot easier.

  4. Mounting the LCD is the hardest part. You have to carefully measure the LCD and set it aside, the more you play with it the greater the odds of breaking it or tearing the very fragile edge mylar cables. Unfortunately the internal bezel of the 150MP doesn’t easily transform to a mounting frame. Someone with a LOT of time could Dremel out the back of the backlight assembly. I found an easier method: I cut 3/4″x1/2″ pine carefully into two frames, held together with flat metal corner braces, that allowed about 1/8″ overlap from the edge of the glass. Then I aligned strips of foam double-sided tape on the wood and compressed the LCD between the two wood frames. It’s just about permanent, you have to get the LCD aligned perfectly before pressing the frames together. After that, I screwed the fresnels directly to the outer sides of the frames, because with my setup I don’t need keystone correction. Ah, before putting the frames together I measured out a lot of centerpoints and drilled a lot of 1/4″ holes for ventilation.

    Anyway that’s one approach. You just need to figure something out that protects the LCD from shock and helps support the edge connectors.

  5. If it does have a stuck pixel, use this

    It’s a quicktime file I found somewhere that quickly flashes green, red and blue. I had a stuck red one which was really annoying in it’s placement and gave it a try. Let it run for 5 minutes came back it was still stuck. Said what the heck, ran it again right over the pixel, and gave it a gentle tap with the finger twice, and it started working!
