Help in fixing Graphics on Sony UltraBook

[sunstar]

Hi,

I have SONY VAIO Ultrabook & the details about my ultrabook is as follow :

SONY VAIO SVP1321WSNB i5-4200U 4GB 128GB 13.3inch

Intel® Core™ i5-4200U (GHz) 1,60

Intel® HD 4400 Graphics

Have installed Catalina 10.15.3 but unable to fix graphics glitches.   It's showing VRAM only 7 mb and when I used config.plist extracted from intel hd graphics 4200/4400/4600.zip file.  After rebuilding kextcache, it splits the screen into small segments and when i use ig-platform id as 0x12345678, it is properly showing the screen but with 7 mb VRAM only.

Please help.
