![]() ![]() they are usually unable to process more complex kinds of color space transformations or compensation profiles. video streams to typical broadcast equipment. they are only designed, to output simple fullscreen video previews resp. In case of decklink-i/o the answer is quite simple, because this kind of devices are really dumb and are not able handle all of this complex tasks, which nowadays computer graphic cards are able to support. This question can be only be answered in two distinctive ways, because output via decklink cards works a little bit different the usual video output via graphic cards on computer screens: icc profiles when I work with Photoshop and Final Cut Pro X or would those two calibration "fight" each other? ![]() Pacific wrote:Would the monitor still be able to access. Some members on this forum will stress that you absolutely need to have a playout card and 10-bit output, but I maintain that it is up to your own needs. Using GUI viewers only can still be acceptable depending on your needs - there will be some colour banding because of 8-bit output combined with the gamma 1DLUT. Make sure to set the LUTs for scopes to "No LUT" or else your scopes will be incorrect. Monitoring is for external output through a playout card, color viewer is for the GUI viewers inside Resolve. Long story short it is the most intuitive to not include the vcgt in any 3DLUTs you make for Resolve.īecause you are not using a Decklink output, you have to set the 3DLUT under the heading "Color Viewer 3DLUT", instead of "Monitoring 3DLUT". You could choose to blacklist Resolve in Displa圜AL's profile loader, so that it will unload the gamma LUT whenever you start Resolve, and apply it again once you quit Resolve, but if you alt+tab out of Resolve while it is running, colours in other applications will be incorrect. If you include it in your 3DLUT (it's a checkbox in Displa圜AL's 3DLUT maker), the calibration correction will be applied twice, which is incorrect. Vcgt means video card gamma table - it's what provides the "calibration" for your monitor in the ICC profile (loaded by Displa圜AL's profile loader). I'm on a single monitor setup (NEC PA271W 27" wide gamut monitor) connected via thunderbolt port).Ĭan you still do an acceptable LUT calibration? You can also load that 3D lut created in the 2nd stage into Resolve Viewer so that the colour page viewer is correct as well.Pacific wrote:Thanks Micha - but what is a vcgt correction? What I can also say is that no matter what app I use to check the colour and greyscale they are all identical, something which I found with v2 profiles there would be some small shifts depending on their CMS. Then I import the first vcgt tables into the profile and save, load into monitor and then the desktop is greyscale corrected and the colour managed apps like PS will have the correct white point but also now correctly colour managed for the colour volume. I then profile the monitor again through that icc profile using a large 17^3 patch run or sometimes a 1000 patch to save time, create a lut and then use Spaceman to create the profile but I do NOT create vcgt tables. I then export that vcgt table into a folder and aslo load the profile into the monitor. So to cut a long story short, I use a normal "photography" workflow where I profile the monitor with a large grey with CS, export the lut to the desired colourspace and create a profile with Spaceman and creating the vcgt tables. So if you don't have the vcgt loaded the desktop white point is as it was precalibration but as soon as you load up a colour managed app then it would apply the calibration from the lut and all is well. ![]() The issue is that the lut has tone curve correction for white point as does the vcgt. I would create the profile with the vcgt tables. ![]() What I found when I first started was that the white point would be correct when checking the desktop through a normal white patch, but when I then loaded PS and other colour managed apps the white point would shift, it drove me crazy. So I have used Spaceman with LS/CS extensivly to calibrate standard gui monitors and I can give you some information that will might save you much trouble if you are looking to use the monitors with apps that are colour managed. Spaceman doesn't 'manage' the vcgt as such, this is done by Win10 OS if you have no other loader such as the Displa圜al Profile Loader to load the vcgt data from the profile into the graphic card. The VCGT is really a 1D lut so no colour volume management. Spaceman can create VCGT data and embed this into the icc profile. ![]()
