    Do you happen to know if there are any 10-bit 60Hz 4k panels out there that would fit the Precision 7740? Basically, what they provide is 4k 60Hz 8-bit, but I'd like a 10-bit display (HDR).

    You're in luck: check out the AUO B173ZAN03.2. It looks like it's barely entered production, though, and you might have to wait a fair while until it's in the market.

    You can choose. If you have graphics switching on then it will attach to the iGPU. There is a BIOS setting for "discrete display output" or something like that, if you turn that on then it will attach to the dGPU.
    If you have graphics switching off then of course it will attach to the dGPU.

    You would think so. I know for sure that earlier models (like in the Precision 7X10) were definitely capped at 60 Hz for the Intel GPU and I do not know if that restriction has been released. It has other limits not based on "total bandwidth" math (i.e. you can only have three displays attached, no matter the resolution of any of them).

    Hmm, I didn't know that. Let's see how things work out this time around on the 7530/40.

    Thanks for the tip. It even has a Dell Part Number on that page. I'll ask a representative about this display panel.

    I've went through the whole forum and read about the power cap on the system. Now my question is, would this be because of the Energy Star rating of the device? If it comes Energy Star Certificated then it should consume less energy. Now, when you build a 7740, you can choose whether you want to have Energy Star rating or not.

    If you order with Energy Star, all you get is a sticker and some different default stock Windows power settings. No permanent change or limits are stored in the BIOS/motherboard.

    The power cap is understood and it seems like it can be overridden with ThrottleStop, if I read the most recent posts correctly? I saved this one with some information.

    My 7540 is here. I opted for the Full HD Touch Screen. For info, the screen is glossy. Prima facie, it is very similar to the Full HD screen of my XPS 15 2-in-1, both in terms of reflectiveness and brightness. The thick bezel on the 7540 screen looks outright ugly in front of the XPS 15. I think Dell could have managed to fit a 17-incher in this chassis and made it an outright killer product.

    Dimensionally, other than the thickness, the 7540 to me does not look overly big compared to the XPS 15. The weight is higher, but not uncomfortable. Seems to be well balanced and sturdy chassis. Hope it is durable as well.

    If it were 16:10, possible; 16:9 17.3" displays are more than 38.5 cm wide, whereas the 7530/40 is only around 37.7cm wide, including the bezels. Bezels are a good thing, however: you can take them off, and service the display separately.

    In my case, the glass runs all over till the edges. It seems a difficult proposition to remove the LCD inside.
