Am I correct on this that this MB offers only 1 video output??? So only 1 monitor can be used?? Is this correct??

A Z790 Extreme MB with only i7-12900K or KS onboard graphics WILL drive 2 monitors. Do do so, you must use its Thunderbolt 4 port together with a USB-C to HDMI or DisplayPort cable. Boot with just the onboard HDMI port connected. Once in Win11 Pro 22H2, connect monitor 2. Press a couple of keys and 2nd monitor should activate. However, onboard UHD Graphics is significantly slower than a RTX 2070 or 3070 card so the latter is a far better choice for gaming &/or video editing..

4090 PCIe4 and fast gen 4 M.2 in the Extreme. For performance do I need to avoid the M.2-1 slot because that "may" slow down the video card? Does anyone know which M.2 slots to use to maximize both the M.2 speeds and the GPU frame rates?

I thought if you used the top M.2 slot with a gen 5 M.2 then it will reduce the lanes of the GPU from 16 to 8 on the top GPU slot. But if you use a gen 4 M.2 the speed will not be reduced, at least that's what I thought.

Why is it the releasing on the 31st when other sites say the 20th? Is Newegg late to the game?

The release date for the ASUS ROG Maximus Z790 Extreme motherboard is mentioned as August 19, 2024, in the provided product information.
