    Yes its very wierd. The early materials made it clear that the HDR400 panel was an extra option just for the 7*40

    But now they stopped talking about the 4k panels.
    What made me think they had a new panel was that the 2 sharp panels that had mounting points was LQ156D1JW02 and LQ156D1JW33 and they had 350cd/m brightness and HDR400 specifies minimum 400 peak brightness. Maybe dell overdrives them somehow?

    There is one oled panel from samsung on panelook that seems interesting but there is no suppliers

    Also:
    HDR400 is only an option for the 7540, not the 7740 (at least that's how it was marketed).

    Because the 17.3" lcd market is near dead, there is a lot innovation on 15.6" lcd but nearly nothing on 17.3" :/

    Asus Studiobook brings back 16:10 on 17" 1920 x 1200, which I would count as "innovation" ;-)

    I hope Dell picks up those panels as well.

    16:10 17" is not 16:9 17.3", it's not comparable at all, they would need to remake the entire design as a 16:10 is larger and shorter than 16:9 display, also like the asus studiobook you will get a smaller keyboard which is a real downgrade for me

    Also the panel used in the asus studiobook seems to be an old display which is not eDP but LVDS so upgrading the display is not possible

    The bezel around the display is still thick... Little space above the display and lots of space below, where the Dell logo sits.

    And why not change the chassis a bit for the next 77x0 to go back to 16:10 displays?
    Would any professional workstation user prefer 16:9 over 16:10?

    Hi

    First, sorry my English is not the best.

    A question to the owners of the 7740
    Is the Precision 7740 recommended, i have read in this thread a lot about the noise emissions and the temeperatures.
    The "older" 7730 has the same problem, Lenovo with the P72 are better in this areas.

    I would like use the 7740 (if i order it) for Video Editing and 3D Modelling (Blender, Modo) and i will playing games.
    Can i play games or this a problem with the temperatures.

    What i have read is, that CPU and GPU throttled.
    Then the best CPU/GPU are completely unnecessary.

    Are you doing all of those things on the move, in an office or while traveling? and how much of % of time are you doing those?

    If you are stationary, then it makes no sense not to have a desktop workstation
    Laptops are portable, that is either your constrained in work space, or are constantly on the go that you must have a laptop, if your staying home 90% of the time and are not using it for work, why have a laptop over a desktop?

    Other laptops will still have temp and throttling, their is no laptop that is powerful and has low temps and does not throttle, that would be an oxymoron, or would not follow physics
    A desktop workstation can handle really long sustained loads both on cpu and gpu without having major heating issues, unless you are o/c and pushing all your hardware to the limit

    Simple, the smaller the laptop the less heat it can handle, if it handles heat great it will be either really bulky or really loud or both
    Because of the smaller envelope of thermals, the laptop will be far less powerful, or can only sustain short burst of high speeds

    They are at the mercy of panel manufacturers here. Precision doesn't drive enough volume to justify the cost of custom displays (like Apple gets for the MacBook), I imagine. @TheQuentincc mentioned that the panel that Asus selected is an older LVDS panel so I don't think that would be a good direction anyway. LVDS cannot handle high-resolution displays like 4K.

    If your applications do multi-threading well, a throttled 8-core CPU is probably still faster than any of the 6-core options, so there may be value in the "best CPU" since there is only one CPU available with 8 cores. Well, there are two, the i9 and the Xeon, but they have the same clock speed and the only difference is ECC memory support.

    The CPU will not be able to maintain the maximum turbo speed. You might have been able to expect that five years ago, but not now that CPUs are pushing well into the high 4 GHz frequencies. That goes for just any high-end laptop now and is as it should be (if there is a system that can maintain max turbo, then there is thermal headroom and Intel should set the turbo clock speed higher).

    I do believe the RTX 4000 is a better value for your money unless you need the high vRAM. I believe that the RTX 5000 will power-throttle and not be that much faster than the RTX 4000. We need to see some benchmark comparisons to know for sure. Waiting to hear from some people who actually have a RTX 4000 card. My experience has been that it is hard to get the GPUs in these systems to thermal-throttle, the cooling is good and they hit the power limit first.

    This is my use case for my M6700 and the answer is simple. I need to be able to easily move it around my house, to be closer to where the action is and not chained to my desk.

    Yes i´m waiting with the order.
    I hope in near future we see benchmark and a review of the 7740.
