LG CF181D Projector Specifications Creative Frame Interpolation: TruMotionSadly, the LG projector does not have one of the better CFI systems. There is a jerkiness that occurs, when watching movies, which is basically unacceptable. I’m not sure if the LG is a little better in this regard than the Epson Home Cinema 650UB’s CFI issues when it came out a little over a year ago. However, the problem with the Epson was severe enough that they managed to upgrade the performance significantly just weeks after first shipment, with an upgrade path for original owners. Click Image to EnlargeThe LG jerkiness is very reminiscent of that. I would not recommend using CFI with movies, even if you might like the effect with some other projectors. The LG’s CFI is what I consider intrusive. You will notice it from time to time, and it’s not the job of a projector to rudely intrude on your viewing pleasure. For sports, I left it on. Again, not one of the better CFI’s but I’ve watched dozens of hours of the Olympics, with it mostly on, and have generally been satisfied. The issues with HDTV signal are not as great as with 24 fps movies. So, adequate for sports, probably skip for most other things. I should note that the LG offers a menu option of TruMotion Demo, in addition to the various settings, under TruMotion. If you engage TruMotion Demo, the left side of the screen uses CFI while the right side does not, so you can compare the effect. This is a feature found on several other projectors including the Epson UB’s. It’s a nice touch for those who “like to play”. Color Management System (CMS)The LG is fully equipped, with a CMS system to adjust the individual primary and secondary colors. It provides, however, only a single control for each of those colors. For grayscale balance, the LG has separate R, G, and B controls for brightness and contrast. We mostly worked with Cinema and the two programmable Expert 1 and 2 modes. Those three offer slightly different controls than all the other modes (operative word, is slightly) with more controls available, including CMS for Cinema and Expert modes. You won’t find the same ability to adjust the colors if working with Vivid, Sports or other presets. Click Image to EnlargeLG CF181D Projector: Dynamic and Manual Iris The iris mechanism of the LG projector offers five choices: Off – which means wide open iris; On, which gives you 32 step control of how far the iris is open (32 is wide open, the same as off); and three different dynamic iris modes. So, you can use the iris manually, or dynamically, but not both (no big deal, but some might say it would be a plus to do both, because the LG is so bright.) The three dynamic iris settings are Auto 1, 2, and 3. For “best mode” viewing, I worked with Auto 1, which provides the least overall brightness (but still plenty) and the blackest blacks of the three settings. Auto 2 is in the middle in overall brightness, and Auto 3, is virtually identical as wide open (at maximum), but doesn’t close down as far, so less black improvement than Auto 1 or 2. I’m definitely recommending Auto 1, for the blackest blacks. There’s plenty of lumens behind Auto 1, so no problem there. I don’t watch with dynamic irises on, on things such as sports, and most general HDTV programming, but, if I did, I’d probably select Auto 3. Overscan Feature, and Edge Masking IssuesThe LG CF181D only offers overscan, and not edge masking. (That’s very common.) Unfortunately Overscan does not work with 1080i or 1080p sources, so it isn’t available when my favorite HDTV channels happen to be running something where there’s noise along the images, as often seems to be the case when low def is displayed – an example might be ESPN running Sports Center HD, and showing standard definition footage of a game. Let’s just say, noise around the edges isn’t rare, though some projectors are better than others to begin with. Click Image to EnlargeThis is potentially an issue, since when you get that jittery noise, say, along the top, you may not be able to rid your screen of it with the LG. As it turns out, the LG is expecially good at handling the type of noise that makes you reach for overscan controls. I rarely spotted image noise along the edges. When I did, it was almost always on standard def TV, which (as long as you don’t have your cable box or satellite box doing the upscaling) allows you to use the overscan. So, while I’d be happier if the LG CF181D supported overscan at 1080 resolutions, it doesn’t seem to be any kind of deal breaker issue. Even forgetting that overscan 1080 issue, I personally prefer projectors to offer Edge Masking, either instead of, or in addition to Overscan. The LG lacks edge masking as do probably a slight majority of home theater projectors. The advantage of edge masking is that the overall image gets a couple of rows of pixels smaller, but you maintain 1:1 pixel mapping for the sharpest image. With Overscan you again eliminate a couple of rows of pixels on the outside, but then stretch what’s left to fill the whole screen. You get the screen filled, but a touch of softness from the expansion, very similar to the softness caused by using Keystone Correction. Image: Sports in particular, including lots of Olympics looked really great – lots of lumens, a sharp image and vivid colors. This shot above, was done in “best mode” our calibrated Cinema (placed in Expert 1). Nice to have the lumens (about 1000) to actually use a “best mode” for sports. That’s something only a handful of projectors are bright enough to accomplish. 1. LG CF181D Projector Review - CF181D Projector Highlights - LG CF181D Projector Overview2.
