BIOS screen is got BIGGER

[fourseven]

hello guys.
I have an Issue here about bios screen is going bigger after I change my cable monitor into DVI-D cable, before that I use DVI-D to HDMI cable and it's work fine but when I turn on my computer this morning I found my computer is login to windows by hearing welcome sound but my monitor showing "no signal" so I assume something wrong with the cable, and I tried to put the cable into onboard hdmi but still "no signal" so I decide to change my cable into DVI-D and that solve the problem perfectly.
But the real problem is when I go into bios, screen resolution is too small with 640x480 and that makes my bios screen is BIG and I can't see the whole menu.
and the bad thing is my monitor doesn't have "auto adjusting" menu in it, I already tried login to save mode and tried to change proper resolution via display properties --> advanced setting --> List all mode, but all of those can't solve my problem.
is anyone here can help me solve the problem?
the computer specs is:
amd a8 7600
asrock fatal1ty fm2a88x killer
galax gtx 1050ti exoc
corsair vengeance 8Gb
and my monitor is HP L2045w with windows 7 ultimate as it OS.

- The Bios itself usually has resolution adjustment somewhere in the menu ( check in both quick easy menu and advanced menu interfaces)
- Try also turning CSM off.
let me know how it goes.

I'm afraid my motherboard BIOS doesn't have resolution adjustment feature, I already looking everywhere and I can't find it. And I can't find CSM setting in my BIOS too

Coming from a motherboard expert like yourself, it almost looks like a trick question

I'm afraid this is tricky one indeed, and this is my first time ever experiencing this kind of trouble.
by the way I already turn of CSM but nothing happened, my bios screen still big.
this is the picture.

I'm leaning towards it being a defective graphics card.

Connect monitor to APU graphics and see what EUFI screen looks like on that - - - if it looks normal I'd say your 1050Ti could be faulty.
