For making visuals in Unreal, which monitor specs are more important, color accuracy and full sRGB color space or fast response time and refresh rate? Or maybe one of each? For example LG Ultragear gaming monitor or Ultrafine monitor? Running from a Nvidia card is a particular brand going to work better ?
If your job is to make lighting, textures, and shading look right, it is more important to have good color reproduction than to have low blur / high frame rate.
If you’re a texture artist or lighting artist (or “look developer” for things like post processing effects and color grading) then you should ideally get a monitor with a calibration feature.
