The only place where I can find that particular model listed is with Walmart. HP doesn't even list it on their site. Walmart will contract out cheap equipment to be sold by companies that are exclusive to them and are generally on the cheap. Normally I would say there has to be a way to adjust the video memory, but knowing that often the electronics sold by Walmart are really cheap, it absolutely would not surprise me in the least if it was not adjustable. The only reference to it I can find doesn't even mention the video memory, only that it is a R7 GPU. It is unusual for them to not mention the memory. Tells me that they are not wanting you to see how weak it is and that is just isn't adjustable. Other laptops, even from Walmart, will say "up to #### GB" for the video memory. With that model, it doesn't say anything. So unfortunately, I fear that it might not be adjustable.
