I don't know how it clocks down at 59.951 Hz because that doesn't match the other monitor exactly. Freezing would be an NVIDIA driver bug, but that might be happening if the monitor isn't staying connected properly. If the PRISM+ can't handle custom parameters, that makes it much more difficult to synchronize both monitors, and I can't even guarantee synchronizing them would allow the GPU to clock down because the driver might not handle all cases where the resolutions are different. If the PRISM+ can handle a very slight tweak to the timing parameters, making all the parameters and the pixel clock a multiple of 4 would allow making a 1920x1080 equivalent by multiplying the parameters by 0.75 and the pixel clock by 0.5625. Technically these two are perfectly synchronized: You should also check the TV resolutions and delete 1920x1080 @ 120 Hz if it's in there. I don't know if that's enough blanking for the GPU to clock down, but if it isn't, I'm not sure what you can do if the PRISM+ won't accept higher vertical totals. |
