[Solved] 3DCoat on 4k monitor is blurry

[ahmad]

hello,

I just bought a 4K laptop with 10th generation nvidia, every 3d and 2d program looks sharp and and clear like Blender and Gimp, 3Dcoat is so blurry, fuzzy and hurts my eyes, I have to disaple windows scaling to make it look sharp but the UI becomes very very small, I dont want to change any windows scaling because all programs look sharp and have options of dpi except 3dcoat, any clues ?

Turn off automatic antialiasing in video diver settings. For example in NVidia settings just set

"Settings according to 3D application"

I have similar problem and in driver settings is the same suggesting option. All fonts looks blurry, in windows 125% scaling ui.

Changing Font size (to avoid scaling windows UI 125%) helps ?

Nope, at all sizes it looks blurry, only at 100% scaling it looks sharp. windows 10 17763

 

100% scaling

According to your screenshots the viewport is sharp. I will explain what happens on example of "Retina" displays under macOS. "3DCoat" supports HiDPI (Retina) displays by rendering more pixels in the viewport. To render user interface elements and text on HiDPI displays "3DCoat" upscales them to maintain the same physical size of user interface on Retina (144 ppi) and non-Retina (72 ppi) displays. I have attached screenshots to explain this. The first screenshot is made on my non-Retina external display (72 ppi). The viewport and user interface are equally sharp because they are rendered without scaling with the same 72 pixels per inch resolution. The second screenshot is made on Retina display of my MacBook Pro (144 ppi). The viewport is sharp (144 pixels/inch). User interface elements are upscaled by two to match those 144 pixels/inch of the viewport. Otherwise the elements would be small. They are blurry because user elements and font textures in "3DCoat" have resolution 72 pixels/inch. Note that "3DCoat" doesn't have any special code to support HiDPI under Windows. "3DCoat" doesn't upscales its user interface under Windows in any case. That "upscaling" becomes from Windows system setting "Change the size of text, apps, and other items" which effects in the same way as I have explained above.

I don't use HiDPI display, i have 43" 4k monitor what have similar PPI as ordinal HD monitors - i have 104 PPI 0.24 mm size of pixel. I can use it in 100% but as monitor is bigger i can't sit in the same distance as 1080 screens so i sit a bit back and change scaling to 125%. 3ds max, photoshop etc looks sharp, only 3d coat looks blurry except very old programs what do not support scaling. I found 3d coat fonts even at old monitor also not good and sharp

Maybe will help for other users. 

I solve this via disabling windows scaling in shortcut preference of 3d coat (needs latest windows 10 build i believe), and increasing font size in 3d coat preference
