  • Panasonic BTLH1700W 17 “hot spot”

    Posted by Michael Mk siu on August 28, 2008 at 8:33 pm

    Dear all,

    We recently purchased a Panasonic BTLH1700W 17″ monitor. It is now hooked up to our MacPro through a Matrox MXO.

    We noticed that when a “black screen” is on the monitor, it looks like the monitor has a huge “hot spot”, the image is not even. This is the case when we are sending a black screen through the MXO to the monitor, as well as when nothing’s plugged into it.

    We are wondering if that is the nature of the monitor, or if something’s wrong with our unit. When we are looking at other things – ie color bars / video signal, it doesn’t seem to be affecting the image. And is only visible when a black screen is there – not with other color matte.

    Any help / advice is appreciated.

    Thanks!
    Michael

    [Michael MK Siu] “We are wondering if that is the nature of the monitor,”

    That’s the backlights of the LCD and why people don’t like to use LCDs. There are other manufacturers that overcome this feature but you have to pay more money.

    See that’s the problem. The 24″ JVC LCD is very nice in my opinion and so are the TV Logic displays. They are more than 3 grand.

    Your Panasonic is a decent monitor, you just have to watch the blacks. Trust your waveform (that they helpfully put on there).

    TV Logic makes a 17″ that’s actually same panel as Panasonic’s, but they put the ND filter on it so the image is much better and their electronics on the back end are better as well. Other than the Panasonic 1700W, that’s the only other monitor I would recommend.

    I’m holding out until I can afford three of the TV Logic 24″ models. Those run $8k each but are the absolute best LCD grading display I’ve seen for both HD and SD.

    This hot spot is not typical behavior, but would be a result of the LCD being bruised somehow. If you just got this monitor, I would take to a Pansonic Service Center to have it looked at. Possibly best to work this back through the dealer that you purchased it from.

    Best,

    Wow 8K for a monitor – oh well, thanks for replies – I know where I can get a 1700W for $1800 (used)…I just hope it doesn’t have the problem of hot spot…

    Thanks

    If it’s only when you are sending black to the monitor, then this is proabbly normal. The monitor looks almost very dark purple when you send nothing but black, right? Does it look like the flouescent tubes showing through?

    (Sorry Jan, this monitor does this, I found out during a night shoot).

    The 1700W is less than $3k new. That’s why I mentioned it.

    Thank you everyone for their input and advice.

    And Jan, seeing how this unit is shy of a week old, and the hot spot was apparent the first time we turned it on, we’ll bring it back to our dealer and have it checked out.

    Thank you again.
    Michael

    Sorry but $8K is nothing for a “true color” reference monitor

    Take a look at a grading displays from CineTal or E-Cinema that start at nearly 2x that, and are the standard for onset color monitoring in hollywood.
