It could be either you need to update the Nvidia drivers to latest or the fact that your graphic card is too old and can only display that resolution. I have a 560ti orso which is very old now and it can do FHD atleast.

What kind of GPU you have?
are you using a VGA-->DVI-->HDMI/DP convert of any kind?

That is strange, Are you using DP or HDMI cable?
But try to uninstall the nvidia driver and update to latest
if that doesnt help,try another cable,could be a faulty cable
Where does it say it can only go @ 1024x768? Nvidia Control Panel or the windows "Display settings"

is it pre built or freshly installed?
either way,go to invidia and download the newest driver with HDMI. if it havent improved try with a DP instead. Even tho HDMI should do this resolution.

it may also be you need to install chipset driver for your motherboard aswell
since its desktop PC,performance and battery life is not factored into this problem.
Find and install DDU and reinstall it with the following url: https://www.geforce.com/drivers/results/141169
Its for the rtx2070
if this doesnt work,try with a DP cable and if its still problem maybe someone else knows or do a RMA on it.
