Inspiron 3043 AiO compatible for dual monitor???
I have a Inspiron 3043 and would like to use dual monitors for my work at home office. I know it does not have video output (vga, dvi-d, hdmi out) but could I use the dvi-d to usb 2.0 adapter to input the second monitor to the usb port? I have a feeling this is possible bc in display settings it shows the second monitor as being detected but the screen is black (yes it is a verified monitor, it works!) and I have tried using the Windows IU display settings to extend the display. both monitors are showing in display settings but 2nd monitor says "no signal" so obviously the hdmi is not putting out (bc it is only hdmi in, I got that)
has anyone been able to successfully use a second monitor with this AiO desktop?? or have I royally screwed up buying this thing?? if no way to piggy-back an extended display (not just mirrored), I cannot use it for work and wasted money buying it.. help please!!
To dell support team: please do not respond to my question with the diagram of the side of the computer and a list of available ports as I have seen in every similar post. I am fully aware of what ports are available and that will not help. but thank you in advance for any usable knowledge shared.

One more thing: Checking the specs of that system, it appears that it only has USB 2.0 ports, not 3.0. In that case, you would be even more likely to observe the behavior I described in my first post by using a DisplayLink display since you have significantly less bandwidth than 3.0, and I've seen those motion issues even when using USB 3.0 DisplayLink adapters. Just setting expectations here.

I forgot to mention that if you want to check about the GPUs based on that last point, go to Device Manager and expand the Display Adapters category. If you have more than 1 GPU, then that last note will apply to you. Note however that I think DisplayLink adapters themselves show up as GPUs there, so check this while you do NOT have that adapter connected.

If the HDMI connector is only an input, then obviously you can't use that. USB display adapters typically use DisplayLink chips, and to use those you need to download DisplayLink drivers, which you can find at DisplayLink.com. If you've already done that and it's still not working even though you've verified that the display works, then of course it might be the adapter. However, DisplayLink displays behave differently from those that are directly controlled by the GPU in some ways that may be significant to you:
- If you have a lot of display area changing simultaneously, such as when watching full-screen video or gaming, then the display might show compression artifacts and/or inconsistent motion. This is because DisplayLink uses the CPU and GPU to compress display data and transmit it as raw USB traffic to the adapter, which then decompresses it -- but USB doesn't have as much bandwidth as regular GPU connections. This isn't normally an issue with regular productivity work, though.
- If you have a lot of other USB traffic, such as transferring a lot of data to a USB hard drive, then the display might exhibit the issues I mentioned above since you might run out of USB bandwidth.
- If the CPU is already busy doing some other tasks, then once again you might see the issues above because it might not have as much capacity available for DisplayLink compression.
- If that system has both an integrated GPU and discrete GPU (unlikely since it's a desktop, but still), then the discrete GPU would never be able to accelerate content being shown on a DisplayLink display. This is a Windows limitation.
