The monitor is connected to the PC via vga-to-Display port, monitor turns on briefly before going black, the duration of the screen working is inconsistent, sometimes it takes a minute to turn black, sometimes it can work up to ten minutes. The GPU (1070ti) also has 2 other monitors connected to it which work without any issues. Monitor has worked before and cables are properly connected. Even when the screen turns black windows keeps track of the monitor, suggesting the vga-to-DP adapter and cable works fine. Is this repairable or would it be more worth it looking for a new monitor at this point?
