TV resolution bugs
Greetings ToastyX,
thank you for such a great software. I noticed two serious bugs when editing TV resolutions. I'm using Sony 2015 KD-55X8505C 4K TV with GTX 960 in 64bit Windows 10. I'm using the latest 362 nvidia drivers. Here's what I did: - Exported the TV's EDID (see the attachment) using Monitor Asset Manager and imported it into CRU. - Changed 1920x1080 60hz->100hz under CRU Custom extension block - TV resolutions. The "native format" option wasn't enabled even though it is the native resolution & refresh rate as shown in the nvidia control panel. I tried both enabling the "native format" and leaving it unchecked. - Used restart64.exe and reloaded nvidia control panel "change resolution" tab. - Noticed that in this tab, 1920x1080@60(native) moves from below "Ultra HD, HD, SD" to below "PC". - 1920x1080 100Hz is added under the "Ultra HD, HD, SD", but in reality this is 99Hz as reported by TV. Causes artifacts (random lines) on the screen. When 1920x1080@100Hz (247,5MHz, see the image attachment) custom resolution is added using nvidia control panel instead, TV reports is as 100Hz and there are no artifacts at all. - As the added 100Hz is not correctly flagged as native/default refresh rate, I'm still getting 60hz instead of 100Hz (or instead of 99hz, in this CRU bug case) when playing any game with the 1920x1080 resolution. All I want is to change the EDID profile so that instead of 60Hz it will default to 100Hz (and not 99Hz) @ 1920x1080. 60Hz should still remain as a supported refresh rate, though. If there's an alternative solution to enable 100Hz in a game that has no option to select refresh rate, that would be great too. EDIT: I noticed that if I load the TV EDID to CRU, then only change the 1080p60 to 1080p100 @ main screen detailed resolutions, I'll get 1080p100(native) under "PC" in the "change resolution" tab in nvidia control panel. This is the correct 100Hz as reported by TV. Also, if I first select this display mode and then launch a game using 1920x1080, I'm finally getting the right 100Hz ingame! But if I'm using the native 3840x2160@60Hz in Windows and then launch the game, I'm getting the normal 1920x1080@60Hz instead of 100Hz. So now we need somehow to get the 100Hz to have a higher priority than 60Hz, even though 1920x1080@100Hz is already reported by nvidia as native, albeit under "PC" instead of under the tv resolutions "Ultra HD, HD, SD". EDIT2: By deleting all the 1920x1080@60Hz in CRU TV resolutions I'm getting the correct 1920x1080@100Hz in-game even when launching outside that resolution. If I add 1920x1080@60Hz to either TV resolutions or Detailed/Standard resolutions in CRU, 60Hz is once again used in-game unless I launch the game while in 100Hz. Finally, If I add 1920x1080@100Hz using the Standard resolution on CRU main page or via the TV resolutions, I'm getting 99Hz with the artifacts instead of 100Hz. Adding it via Detailed resolutions or nvidia control panel gets me the correct 100Hz. Thank you for any help. |
