Geometry - Lines are crisp and well defined. No complaints here. Convergence - This deals with pixel alignment when different colored pixels are placed next to each other. Even at 1280x1024 some misalignment is noticeable, though it's to be expected. Resolution - The monitor has no problem creating smooth 1 pixel high/wide alternating lines. Moiré - Since moiré deals mostly with CRTs, there was no interference in any of the tests (even using the analog connection). Brightness and Contrast - This test is more for adjusting brightness and contrast rather than "benchmarking" it. Focus - Test consists of two patterns shown in RGB. The monitor displayed all patterns perfectly without any interference. Readability - Test displays a lot of repetitive text, black on white and white on black. Everything is sharp and crisp with no blur. Color - RGB and black/white are displayed full screen. The white seems just a tad cool, but that could just be my eyes. The colors are perfect. Screen Regulation - Test used to measure high voltage regulation reliability. If poor, screen will contract in darker areas and expand in lighter areas. No noticeable problem here. While somewhat synthetic testing is important, real world application is more so. After writing, working, and gaming on the 729A for several days I have to say I'm impressed. It's not the best 17" flat screen you can get, but given the investment (around $200 at the time of writing), there's not much more to ask for. The 16ms response time is in fact ghost-free. Color reproduction is great. One of the best features I've come to rely on is the turn-on time. Unlike CRTs and several other LCDs I've used, there's almost no "warm-up" time for the 729A. Hitting the power buttons turns it off instantly. Hitting it again either turns it on instantly or at worst there's a 1 second delay. I did notice a few things though. First off, there are a few bright spots on the monitor. This isn't something that can be entirely eliminated, but it can be reduced. With the 729A they're only noticeable when the screen is completely dark. Our sample also had a couple stuck pixels (both of which were blue). This is often more about luck than quality though, as very few companies (Samsung among them) have a "no dead pixels" policy on some of their displays. Once again these pixels aren't noticeable unless the screen is either all black or all white. Finally, the built-in speakers are good for basic audio, but given their low output power and complete lack of bass reproduction, anything more requires some "real" speakers. Pros
