FreeBSD Screen glitches after boot in UEFI mode


Hello everyone, i want to try FreeBSD on my PC(i don't want virtual machine), so i tried to install it. I have problem, because when i boot FreeBSD in UEFI mode loader is fine, but when i boot OS screen becomes glitchy. When i boot in Legacy, non UEFI mode everything is fine, screen is ok. I must install it in UEFI mode, because already installed operating systems(Linux and Windows 10) are installed in UEFI mode and i don't want to format and reinstall they in legacy mode. I think it can be resolution problem, because loader is too small, and console is too low, because it is black belt in bottom of the screen(with the remnants of loader inscriptions). I can use OS normally, but i can't see what i'm doing. In attachments it is picture of my screen after boot(installation image in USB memory). English isn't my first language so i'm sorry for mistakes.

PS: Sorry, i forgot:
FreeBSD version: 11
Graphics card: Hybrid, Intel HD4000 and AMD Radeon HD7670M
RAM: 8GB
CPU: Intel Core i3 3110M

Windows 10 does not run on legacy. Does it? I have one current laptop and one netbook that needs my attention. But where there is no M$windows I have always installed BSD with much ease.

Hope that helps.

I don't understand your question. I have Windows 10 and Linux both in UEFI mode. I don't want to format and install they again in Legacy mode, so i want to install FBSD in UEFI mode.

Windows 10 can be installed on Legacy mode. I had Win10 and Linux in Legacy mode, but some months ago i reinstalled they to UEFI mode.

I never used FreeBSD, but I would try to set the graphical card to be used in the firmware's menu.

For instance my laptop's firmware allows me to use only integrated graphics (Intel), only discrete graphics (Nvidia in my case) or both (the card to use being then chosen by the OS). Maybe you'll get bests results with one of your two graphics cards, so try all possibilities.

I would try, but in firmware settings i don't have option to choose graphics card. I can switch graphics card only by operating system i can't switch they manually in firmware settings.
