I presume you meant 1024*768?
See this post for interrupting the boot. On the linux/linuxefi line, try adding vga=791 (16-bit colour) or 773 (8-bit colour). This is method is deprecated but probably still works. If it works for you,then you have to make it permanent by changing grub2 as this only changes it for the one boot.
The preferred method is using something like "set gfxpayload=1024x768x16" higher up the boot options and it would be best to use this when you regenerate grub2 if the vga=791 works. -

Maybe since the vga= method was deprecated a while ago, it has now been removed from the kernel.From one of the links I used, instead, please try setting the lines:
after you interrupt the start up process.GRUB_GFXMODE=1024x768x16
GRUB_GFXPAYLOAD_LINUX=keep -

Hi to all,
ok i have try this: as root
# GRUB_GFXMODE=1024x768x16
# GRUB_GFXPAYLOAD_LINUX=keep
# grub2-mkconfig -o /boot/grub/grub.cfg
# reboot
i can login in the red text box, after this F2 and there is coming the same issue.
So the bootparameters are ok but the resolution of Clearosapi or X11 is -

I've dug out some old posts about configuring x11/xorg:
https://sfj48-fkj200.heiksthsd.cf/clearfoundation/social/community/graphics-resolution-of-local-graphical-console
https://sfj48-fkj200.heiksthsd.cf/clearfoundation/social/community/howto-configure-your-webconfig-x-resolution
https://sfj48-fkj200.heiksthsd.cf/clearfoundation/social/community/blank-screen-after-clean-install-no-login
The first one indicates you may need to create your own xorg.conf before you can adjust it.
Do you know if your card supports 60Hz? I think you only need an 800x600 display for ClearOS but I'm not sure. -

Graphic-wise, if you must have video output, you may have a bit of a road to travel for obscure monitor and video card drivers. Luckily, ClearOS is meant to operate headless, so if you can get the IP address off of the server, skip the pain and torture and just use the web interface. You can find the IP address by using CTRL+ALT+F3 to switch to the F3 console. Log in as root and run:
ip address
This will show your your ip addresses if your box is on DHCP. Simply put that into your browser and go to town.
If you need to manually set up a static IP address, you can modify the appropriate NIC file in /etc/sysconfig/network-scripts/ifcfg-NICNAME using 'Method 1' here:
