This web page at ASUS has the specs for their GT 730 (with GDDR5) which should be similar to the GPU you have. And this page at Newegg of the Gigabyte with GDDR3. And of course Tom's Hardware here.
Dear Community I was able to find most solutions by searching, but this info I wasn't able to. I bought a Vostro 5880 i5-10400F (no Intel Graphics)  with GT730 in Feb 2021 for my mom from Dell.  At that time the monitor included was 1920x1080 HDMI great. However, I want to upgrade the monitor to 2K or 4K.  This card has HDMI/DVI/VGA output. Questions for Dear neighbors:  Can I buy 4K (3840) or  2K (2560) monitors with this graphics card? 1)  What is Max resolution on this 2021 GT730 ? can HDMI do 4K at 30hz ? Can it do 2560x1440?    DVI ?  2)  If this 2021 GT730 can't do 4K,  what 4K cards does this Vostro 5880 support ? i.e. fits power requirement ?  Wouldn't upgrade the power supply as that's too big a project. Very much Appreciated ! --Vincent
