Signal Processors

Recall the almighty signal processor that we talked about during our Albatron LWX-30AMS review? Unfortunately, the Albatron LCD TV used an obscure, under-powered signal chipset as a transitional chip before adopting a much more capable PixelWorks processor. Syntax looks as if they got it right on the first try, going with the PW181 DSP. PixelWorks' website has more information on the chip. Essentially, the PW181 acts as the CPU for the LCD, pulling the functions of the other chipsets on the LCD into one signal relayed directly into the panel.

Below, you can catch a glimpse at Silicon Image's HDCP receiver. Obviously, the processor is not capable of 1080p, but 720p and 1080i are fully supported.

And below is the analog counterpart of the HDCP receiver from Analog Devices.

Pulldown, interlacing, and Macrovision are all processed on this chip below. In the bottom left corner of the image, you can also see Fujitsu's logo on an IC.

For the most part, the remainder of the ICs on the board control analog TV switching, cable TV processing, and audio processing. There is not a dedicated audio DSP like the SRS-WOW found on the Albatron LWX-30AMS.

    Nice review, although I would have liked a little more information in regards to component input quality vs DVI input quality. I sure it would be similar, but as the owner of an AWI 9800pro wanting one (syntax olevia 30') to use as a second monitor, it would be nice to see a comparison of the two input methods.

    Anyone out there have any input as to how the component input would compare to the DVI input (or VGA, as I might buy a PCI vidcard) with relation to Powerstrip & gaming etc. let me know.

    thx.

    I meant the 30 inch lcd display

    apple was saying how they are the first to bring it out but now they're not alone.

    Yes the resolution is crap in comparison but it's literally half as much ($700 video card needed for the apple). For another $500, you'll be able to get a high resolution LCD soon

    "... screen capable of 1080p." It should be 1080i.

    However, how or why would you consider interlacing a signal on a digital display?

    still crap compared to the new apple one, half the price, but that's won't mean much when you try to use it for some gaming.

    not sure what they were tryign to accomplish with this monitor, maybe just the typical sheep-milking, imagine that.

    Those game screenshots look tinted blue alot and the UT2k4 one looks like it has too much red :(

    But shouldn't ratings be given out be comparable to other products at this exact instant in time? Going along with your logic, in 10 years or so every single product you review would get 5's and there'd be no point in doing reviews. It's just like how game sites review games -- a 9.0 5 years ago would get maybe a 5 today. You need to keep raising your standards to match the rate at which technology is progressing :p

    "Stealing apple's thunder"

    Resolution: 1280x768
    Apple's Res: 2560 x 1600

    "LCD quality has improved dramatically enough that we need to reevaluate our subjective benchmark. I am open to suggestions if anyone has them."

    Have you ever considered renting a high-speed video camera(1000pps should suffice) and determining actual response times? Perhaps you could test 10-20 or so color transitions in addition to the black-white-black time they provide us with now. If the expense is too great to do this often, maybe a single article devoted to this with every lcd you can get hold of would be possible. I would definitely like to see the response times from some of the worst case scenarios on the new 12-16ms lcds. You could find some good transitions to test here: http://www.extremetech.com/print_article/0,3428,a=...

    Zebo we used to give out 3s, 2s, and even 1s. To be honest, in the last two years LCD quality has improved dramatically enough that we need to reevaluate our subjective benchmark. I am open to suggestions if anyone has them.

    I guess it's an unwriiten rule when using a 1-5 scale never giver an average 3? 25 ms could'nt be anything else but a 2-3.

    I'm going to assume from now on since I've never seen below a 4 in any of these monitor reviews 4 means below average, 4.5 average, 5 good.

    This is a lower resolution part than Apple's solution ...
