VIDEO MEMORY MONITOR 720P

I see online that someone wrote a BIOS hack for that laptop that allows increasing the GPU memory allocation, but I'm not sure I want to go there.

VIDEO MEMORY MONITOR 720P

Note that I've used Windows spanned across the built-in 768p monitor and an external 1280x1024 monitor no problem over VGA, and even played a 720p video on that and it worked fine. I suppose it could be related to driver issues but I'd guess it's due to the very little GPU RAM present. I could play video on the primary screen or the HDMI, but could not do it on both at the same time. I'm sure it's fine for its built-in 768p screen, but I've run into problems playing video out of its HDMI port, and I'm thinking it's due to the GPU memory limitations. On my laptop with Intel GMA4500HD, it's locked to 64 MB (and I can't change it), out of the 4 GB memory there. I'm just talking about playing a single 1080p video on one screen while working in say Office on the other. What about dual screens? I'm not talking dual 1080p videos. However, when I tried Blu-ray on that, it was only a single screen. That seems to match the system requirements that Cyberlink has for 2D Blu-ray, where they suggest 256 MB RAM. I've played Blu-ray on that system and it worked fine. On one system I set it at 128 MB out of 3 GB but I have the option to go as high as 256 MB. The reason I ask is because I have two systems with shared system memory for the GPU. I'm curious, what is the recommended memory amount needed for Windows 10 dual screen usage, for say 2 x 1920x1080 screens? This is for an extended desktop with office application usage and 1080p video playback, including Blu-ray.
