T430 won't boot past logo screen with external monitor
This is similar to a more well-known issue where the computer won't boot past logo screen with an eGPU attached to the EC2 slot, but in this case it's the external monitor.
Thinkpad T430, i7-3632QM, 8GB RAM, Windows 10 pro 1703, BIOS ver. 2.79
EXP GDC 8.5c with expresscard, MSI GTX 1070, Corsair HX850.
Samsung S32D850T monitor, connected to the DVI port on the GPU via a HDMI to DVI adapter.
Everything works fine without the monitor. It gets recognized, newest driver installed, no error 12, error 43 fixed with the script:
The problem is if I try to turn on the computer with the monitor attached to the GPU, it would not get past the logo screen. Also works flawlessly if I attach the monitor after the logo screen. Exactly the same issue except it's the monitor not the eGPU. I played with the PTD switch on the EXP GDC but it did not seem to do anything.
If I attach the EC2 adapter after the logo screen it does not get recognized at all.
I don't like having to plug and unplug the monitor every time I turn on the computer, so any advice on how to get around it would be appreciated. This setup has worked before on an Acer E1-471G with a mPCIE cable.
Would your system be shutting down? Is that what you mean by not going past boot screen? or do you mean it gets stuck or restarts?
This could explain my issue. Thanks!

I have the same issue.
The thinkpad just freezes with the logo still displayed.
I have to remove all external monitors to boot. I can only connect them after I booted to windows.
No Error 12 nor 43 left, thanks to nando's software an the 43 fixer.
Newest bios 2.80 is installed. PTD set to 7sec or 15sec doesn't change anything.
The solution to the problem is to use the system in UEFI mode.
I am using the Windows 7 operating system as UEFI and I am not having any problems on the BIOS screen.

@peter_qin, Hello peter, did you manage to solve this issue? It seems there is no clear answer to this. I am using the same card (Asus gtx 1070 strix), same laptop, but the only difference is that I am using the BPlus PE4C-EC060A 3.0 dock for the GPU. I have tried all sorts of stuff in the BIOS settings. Setting it to Legacy only, UEFI only. Nothing seems to work. Any solutions would really be appreciated as it is a pain to be unplugging and plugging the HDMI cable to the GPU for every restart or boot.
I got the same problem with my lenovo x230T. The computer freezes at the boot screen.
To prevent this I have to either unplug my external monitor from the egpu or turn the monitors standby mode off before I turn on the computer.
Once it passed the boot screen I´m able to turn on the external monitor.
As Lemaya stated the PTD Settings has no effect.
This issue has been around for a long time now, is there a known solution so far that enables us to avoid the bootup hassle completely?
