Core i9's such as this one: https://ark.intel.com/content/www/u...0900k-processor-20m-cache-up-to-5-30-ghz.html Have integrated graphics. You can buy an older graphics card such as this which supports 6 monitor output: https://www.dell.com/en-us/shop/vis...jLHNeqAGBL3vzDmLDbSxFfVEVvRyw-tNfFTaSATi3Fh-e No system requirement for the CPU.
How are the CPU graphics on that chip? Seems a trader could run 4 monitors and not bother with a dedicated video card.. ??
Depends on what you're using it for. For trading, yeah, I think a 4 monitor setup on integrated graphics would work just fine. Most trading software is not doing any advanced ray tracing or 3D texture. The bigger issue would be finding a motherboard that has 4 monitor output. Most only bother to put 2 display output even if the integrated graphics supports more.
Only 2? Bummer. Recently one ETer tried to run multi-monitor on an i9-12900 chip, mixing onboard video with a decent workstation video card. I'd thought he wouldn't be able to get all of the monitors to work... to my surprise, he did. But unfortunately he had video problems with the whole array which he couldn't get solved and ended up returning the computer and exchanged for a REAL workstation with proper video cards. Still my view there is potential trouble mixing video outputs...
Yeh, the percentage of people needing more than 2 monitors is relatively small. Most people who still build their own computers are interested in gaming and only use one monitor. Otherwise, it doesn't really make sense to build your own PC anymore. Cheaper to just buy from an OEM unless you already have decent components that you want to use and plan to upgrade often. If I was going to do that setup, I would look for a low-power video card with 2 display ports. Then do a little research and make sure the setup would work before buying.
