What's "embedded" video, if not what laptops have had since... Idunno, the Bronze Age?

Lots of at least Intel integrated video chips support up to three monitors. From https://www.intel.com/content/www/us/en/support/articles/000025673/graphics.html : For the following graphics products, most combinations of HDMI, DVI, VGA, DisplayPort (DP), Embedded DP (eDP), and Intel® Wireless Display (Intel® WiDi) support three independent displays: Intel® UHD Graphics 605/610/620/630 Intel® HD Graphics 610/615/620/630 Intel® Iris® Plus Graphics 640/650/655 Intel® HD Graphics 500/505/510/515/520/530 Intel® Iris® Plus Graphics 540/550/580 Intel® HD Graphics 6000/5500 Intel® Iris® Graphics 6100/6200 Intel® HD Graphics 4200/4400/4600/5000 Intel® Iris® Graphics 5100/5200 That last one has apparently been around since 2013, and is integrated onto the processor itself. How much more "embedded" do things get? https://www.notebookcheck.net/Intel-Iris-Graphics-5100.91977.0.html : The Intel Iris Graphics 5100 (GT3), also called HD Graphics 5100, is a processor graphics card included in some of the Haswell processors of 2013. -- Christian R.

Many desktops now have two video ports, but I'm not sure if they support two monitors. I've also seen some with one HDMI only. I know that if you plug in a video card, the on-board video is automatically turned off, thus I just make things simply by installing a dual monitor video card. My time costs more than the video card. Edited by Andrew Grygus June 12, 2020, 07:08:16 PM EDT Expand All History

My personal desktop here (which I built myself) has on-board graphics with DVI and HDMI out, which provides multi-monitor support. I don't use that, having a fast graphics card (AMD RX5700XT) for 3D work and games; this has 2 DP ports and an HDMI port, all of which can be used together. I think the two DP ports can also be used together with a single monitor, to drive very high resolution displays such as 8K.

But the display wouldn't show 4K on HDMI on the MacMini. I had to use a DisplayPort cable for it. Maybe that's a well-known issue, but it annoyed me for a while until I figured it out. There are still too many connectors. It's getting to be like plumbing connectors... I suppose once everything kinda standardizes on USB-C, then Apple will start using optical fibers to connect everything... Oh, and don't get me started on USB-C docks. I'm using one with my L390 laptop to drive 2 older Dell monitors and that works fine, but if I plug in a USB memory stick into the same dock then the monitors go blank. :-/ Grr... Cheers, Scott.

Far too many of them have HDMI plus other more desirable stuff - I'm thinking HDMI must be stupid cheap to add, given there's a way to get it directly over the USB-C connector. 2x USB-A plus HDMI. USB-A, SD card reader, HDMI. USB-A, USB-C, HDMI (Apple's standard one, actually). 2x 4K HDMI. Umm. It took me months to find a simple 1x USB-A socket. I settled for a "hub" that has three USB-A sockets plus inexplicably an Ethernet port, too! Standards are wonderful - so many to choose from. Wade.

The embedded graphics provides a way to do all the fancy schmancy drawing to an image buffer or three but it still needs a physical interface chip to provide a usable offboard connection. Laptops will typically have at least two: one driving an LVDS connection to the screen and a second (or third) driving sockets such as HDMI. But motherboards often have just one driving a HDMI or DisplayPort socket. Thus the limitation. Wade.
