After Apple logo HDMI stop working, only VGA work (GTX750ti)

[mirkonit]

Hi guys, I need some help:
I have Asus GTX 750Ti and 21:9 monitor that have only HDMI port.
After apple logo charging (after installation and nvda_drv=1) the monitor have no signal.
I tried with another 16:9 monitor by HDMI and I have the same problem but with VGA it works perfectly!
Now, how can I able HDMI port for my 21:9 monitor?

ps: may I flash vbios?

sorry for my bad English!

Yes, it's most likely because of the incompatible Asus BIOS. You don't need to flash a different one, using LoadVBIOS in Clover should be sufficient.

Also try a DVI to HDMI cable. Nearly always works. If you need 4K there are some tweaks you can apply (pixel clock patch).
