There must be quite a few people running emulation via a PC monitor instead of HDMI TV.
Has anyone created a Scanline overlay/mask at 1440x900 res they could upload please?
I was looking at using Floob's excellent rp-video-manager for RetroPie, but it is set-up for 720 & 1080 displays https://github.com/biscuits99/rp-video-manager
I would have thought there would have been something on PC emulation forums, but I have not found anything. I would say 1440x900 is quite a common screen res.
