    Hi Guys,

    Last time I looked 30" monitors were well north of $1k, and 27" just
    under. This was only a few months ago. Doing the regular year-end
    perusal I didn't see 30" at the usual stores but stumbled upon 27"
    monitors starting at about $230 (Sceptre, never heard of the brand), to
    this ViewSonic for $300:|1||P_SignDesc1&lang=en-US&Sp=C&topnav=

    This is the Sceptre:|1||P_SignDesc1&lang=en-US&Sp=C&topnav=

    I suppose like usual, only online, but not sure. Reviews are great but
    are they good for serious CAD work? Any brands to prefer?

    1920*1080 is a weird resolution. My PC doesn't have that. Strange.

    Toshiba 40" At $400.
    Where the **** do you shop? Did they see you coming?
    Asus 27" at $339

    This was only a few months ago. Doing the regular year-end

    I would never buy a unknown name brand from a cheap Chinese nobody with
    very likely ZERO service reputation.

    Then you also have a SHIT graphics card, because that resolution has
    been in use for YEARS.

    My 23" LCD Samsung is at 2048 x 1152 ! You can't even see the pixels.

    NONE of them are as pricey as you claim.

    Here's an LED backlit one.

    Are you shopping from Siberia?

    Even the 3D job is A third of your claims.
  3. They're using cheapie 1080p TV LCD panels rather than the former
    standard 1920 x 1200.

    I'm sure they don't compare to a 30" 2560 x 1600 monitor, but as
    you're getting around half the pixels for around 1/4 the price, maybe
    it's worth a look see, especially if your eyes don't like 0.25mm

    BTW, I know you like to aim at a 'maximum value' rather than
    performance price point, but others might find this interesting if
    they're running serious 3D CAD applications. Reportedly Solidworks is
    set to (re)introduce 3D display support.

    I think we do fine as is, but support of 3D displays (perhaps it will
    be stable in a year or two) would be a pretty cool development.

  5. Find a IPS panel, 16:10. Beware of the Dell tint issue, but they are
    lovely monitors ;D

    Sceptre is a fairly common, though cheapie, brand.
    They just bought us Dell 22" 1620x1050(?) monitors. Junk! I doubt the
    Sceptre would be worse.

    I have a Soyo 24" that I paid $270 for a little over three years ago. It's
    been a very nice monitor. I'm tempted to grab another, but I can't get a
    third monitor working.

    2560 over 30" is a 0.29mm pitch, idiot.

    My 23" at 2048 is 0.28mm.

    AFAIK, there are still to this day, NO LCD panels with such a fine dot
    pitch on the pixels. Those are CRT day pitches.

    It is total crap.
    They are both shit.
  10. You're the idiot this time. 30" and 23" are diagonal measurements.
    The dot pitches are 0.252mm and 0.249mm respectively.

    The 27" 1920x1080 works out to 0.311mm, so Speff is right and you're wrong.
  11. It's grade 9 math:

    16:10 aspect ratio, for 30" diagonal, the horizontal dimension will be
    25.4" ~= 645mm so the pitch will be 0.25mm.
    Utter nonsense. Medical grade monitors are available off-the-shelf
    that are 0.21mm pitch. Even my ancient (2002/2003) Philips 200P3s are
    0.255 mm.

    1920*1080 is a weird resolution. My PC doesn't have that. Strange.

    If you're running windows there's usually a check box somewhere that
    stops it displaying resolutions the monitor can't handle.

    I said month ago, not today. And gave evben lower prices in my links.
    Oh, and I will not buy at Frys, absolutamente not.

    Ok, but what happens if the graphics hardware in the PC does not support
    this TV format? If that ends up blurring stuff it's not going to be good
    for CAD.

    For mechanical design I can see the value but the main reason for me is
    that I need this for layout reviews. Which I have to do at an increasing
    number these days, to advise on EMI improvements. Often you have to see
    the big picture but at the same time look at details, such as trace
    lengths to 0603 bypass caps. Right now on a 21-incher it's panning and
    zooming like crazy.

    This is also why a dual monitor setup doesn't do much good here.

    My color vision ain't perfect anyhow (sez my wife, when I pick a tie
    ....). All I really care about for the monitor is resolution and sheer
    size. 30" would be great, 27" ok, 23"-24" wouldn't be worth it versus
    the (excellent) 21" CRT I have right now.

    Ok, but what happens if the graphics hardware in the PC does not support
    Right click on screen, Display Properties -> Settings -> Advanced -> Monitor
    uncheck 'Hide modes this monitor cannot display'. Then back to settings
    to see your options.

    This machine's 5 years old with a Matrox P650 and doesn't show 1920x1080
    but any 'recent' card should handle it. (The P650 would probably handle it
    with a driver update).

    Wow! Now that's what I call a work station. But I don't quite have the
    space for that.

    I have that, sort of. A seperate computer (laptop) to my left,
    networked, so I can pick the corresponding module spec or schematic from
    the same server. But that doesn't help much in layout reviews, there it
    needs to be all on one large screen.

    That's what Michael was also hinting at but how does one find out?

    Windows has been dumbed down quite a bit, probably at least in part by
    an OEM process. Same with BIOSes. I have the G33 chipset in there and it
    seems it supports these formats:

    Says "640x480, 800x600, 1024x768, 1280x1024, 1600x1200 and 1600x900"

    Oh, and the PC manuals are dumbed down as well. In the 80's you even got
    schematics, nowadays it's "Take big cable, plug in wall outlet, see
    picture" :)
