A:Answer For onboard graphics it technically supports 3 displays but this box only has 2 outputs for onboard graphics. One HDMI and one Display port, so you would have to split one of those if you want video to 3 screens from this PC. I personally have never tried an HDMI split set up like that so I don't know how well they work. If you are curious about the onboard graphics for this PC look up the specs for the UHD 630 integrated graphics. I bought the i7-10700 version of the XPS8940 with 8GB of RAM. I removed the 8GB stick, sold it on EBay and installed two 16GB sticks of DDR4 3200mhz of RAM so that I can use the onboard graphics and still run the many things I need to run. I am using both outputs in UHD at the same time and the performance is very good. With only 8GB of RAM you really would need a graphics card to get OK performance all the way around. I don't feel the need to get a graphics card at all with the 32GB of RAM, UHD 630 and an i7-10700. This processer is not the baddest one in the land but it is a beast!! Low power consumption and just chews through everything I throw at it. I love it. Granted, I am not using the stock 1TB HDD> I threw that in the pile of things I will never use. I installed a 1TB Western Digital SN750 for the boot drive and two Samsung 2TB SSD's to use instead.
