![]() ![]() ![]() vertical frequency too high (all above 76 Hz) vertical frequency too low (all below 48 Hz) horizontal frequency too high (all above 84kHz) There is a small hint from my monitor (at least for me) that it is possibly not a violation of the monitor accepted range: My monitor gives an OSD feedback about range violations, it does so for I myself can´t test if it is the driver or the device, because how will I know that the resolution is "fired" through the DVI/HDMI port (so no restriction of the driver) or not? ![]() Is it really coincidence that both of my devices (TFT monitor and DLP projector) can exactly go down to hblankmin 57 and not any further? If so, then AMD seems to have made a useful restriction, if normal devices (I consider I have "normal" devices) can´t go below 57 hblank. The behaviour is the same like described above. I tried driver 16.11.5 and tried patched and not patched. Quote:Are you sure the monitor can handle lower horizontal blanking values? A monitor can accept lower porch/sync values and still limit the total blanking. I'm seeing an issue with RX 480 cards that causes the screen to turn to colored snow with lower horizontal blanking values, but that's unrelated to the 56 limit. The ReLive drivers might have an issue that prevents lower horizontal blanking values from working correctly even with the limit removed. 55 / 1 / 1 is accepted!).Īre you sure the monitor can handle lower horizontal blanking values? A monitor can accept lower porch/sync values and still limit the total blanking. the monitor itself shouldn´t be limiting because it accepts values down to 1 for front porch / sync width / back porch when using total blanking values >=57 (e.g. When using values below 57, the according display device simply turns off (monitor goes to energy saving mode, projector doesn´t sync and shows black picture).

On a side note, there was someone on youtube using the same monitor as me and he managed to get his monitor to 100hz so it is reassuring that its capable of that. So it looks like the patch is missing something, is there anyway manually of doing it then as I am still craving those extra Hz's. I used the frame skipping test already and it went perfectly fine and should do to much higher refresh rates (its a very good panel). It must be hitting the 297 hz limit then, because 73hz is at a pixel clock of 294mhz and 74hz is 298mhz. This should be noticeable simply by moving the mouse cursor, or you can use this test with a camera: Maybe the patch misses something that affects the Fury, but before going any further, are you sure the monitor can display higher refresh rates without skipping frames? 2560x1440 monitors with multiple inputs usually have scalers that can't handle higher refresh rates correctly. Thanks in advance!ĪMD cards have a 297 Hz limit with HDMI 1.x, but the patch should get around that. I honestly don't know whats stopping my PC from recognizing anything more than 73hz, but I do know that HDMI 1.4a has a max pixel clock of 340mhz which does mean that I should be able to overclock the monitor to at least 84hz. Anyways so far I have tried installing different versions of the AMD Crimson Drivers, patched the drivers using your tool over here, disabled the signing of drivers through windows and finally made different types of custom resolutions using CRU. As the monitor unfortunately doesn't have a display port output, I have it connected with a HDMI 1.4a, connected to my R9 Fury which doesn't support the monitors other output which is is Dual Link DVI.
