Still.. nvidia drivers didn't allowed it to fully work. 3840x2160 @ 60hz became my native resolution, and I lost 4096. 2560x1440 @ 60hz were in the PC section resolution. But since my TV doesn't support 2560x1440 when I select it, I get unsupported signal. The good part is that GPU scalling option is available - it's not available in HDTVs according to Nvidia. The bad part is that it's limited to 30hz only. I've found a user stating this on a forum: 1) At 60 hz, the GPU will not allow scaling from 1080p->2160p because of limitations with NVIDIA's MST implementation. I believe this might be the case here. Some limitation on Nvidia drivers. Everything is set to 30hz when GPU scalling is on, even 640x480. I tried a few games, Alien Isolation, Call of Duty Modern Warfare 3, The Witcher 3. The first 2 reported 30fps with fraps on 2560x1440, when selecting this resolution in game. The witcher 3, oddly, reported 60fps in the same resolution. Still there were a few graphical glitches and artifacts. I believe this is as far as EDID overriding can go. Your software did exactly what needed to be done setting the correct native resolution, allowing the desired resolution to be available in the menu, enabled GPU scalling, forced PC mode. The least I can say is thank you Toasty. A shame gpu scalling is bad implemented in Nvidia Drivers. More information from nvidia forums: I think he meants that with the current windows drivers you can't scale to 2560x1600 on a 4k display using MST (which is a driver limitation and not a hardware one, doable on linux). And to Mechan81 yes you can add an additional monitor running at 2560x1600 if you want over DVI or HDMI (although there aren't many 2560x1440 or 2560x1600 displays that can do that over HDMI). |
