Screen resolution in WinPE 5.0 on UEFI devices

Hi

Can you please help me with the issue i am facing? 

The screen resolution in WinPE is very high, the drop down values in MDT wizard are extremely small and almost unreadable. I see a similar question posted on technet for screen resolution in WinPE 4.0 but I am unable to fix it.

The HTA screen looks OK but the when you select the drop down, the values are extremely small. 

I also referred to the article from Johan

Below is my setup:

1. MDT 2013
2. Windows 8.1 x64
3. Lenovo Thinkpad Tablet 10 (UEFI)

Tried the below but no luck:

1. Changed the ColorDepth to 32 in unattend.xml in WinPE pass
2. Tried modifying the Wizard.hta with different screen size and style.zoom

Playing around with the HTA settings might help but i am unsure how it looks and behaves on other UEFI devices.

Currently we are using Lenovo Tablet 10 but soon will also be using Surface Pro.

Am I missing something or is there a better way to do fix it?
