Jerry I've just purchased a basic Acer desktop with a GT730 installed and W10 Home Premium - It's unusable.
I decided to install a copy of W7 and intentionally looked for an early driver which supports this card (circa 2014).
After considerable time on this machine I'm having no luck. There is visible dithering/flickering of some sort happening. The contrast/white levels, even on Windows 7 just seem more 'harsh white' than my 2009 Intel GMA HD machine. I've downloaded a display profile for my display (Dell U2414h) and while it made a difference in the colour balance, didn't change the flickering/harshness of the screen.
They've also blocked the extra HDMI ports on the motherboard, so I'm assuming only the discrete graphics will work on this PC.
Jerry, did you find a driver for Windows 7 that works for you?
