How to get best image quality on a 1080 modern screen

@Tasio GBA Looks really good!
I tried setting up my GBA with the same shader, but I couldn't select it in the Configuration menu. Do I need to install it first?

Tasio

@Capt_MorganCreek thanks for the feedback, I'm glad you like this configuration. I haven't install any additional shaders, I think an up to date Retropie should have it.
This is the path where I have set it up:
RetroPie -> Configure basic libretro emulator options -> configure additional options for gba -> video shader file -> 451 shaders_glsl/handheld/lcd-shader/lcd-shader.glslp

Alternatively you can select this shader from the retroarch menu following this path:
Load shader preset -> shaders_glsl -> handheld -> lcd-shader -> lcd-shader.glslp

Thanks for the suggestions folks! I have settled on the CRT shader as the optimal option for 8-bit/16-bit, but will need to fiddle with these extra variables (integer scaling).

@Tasio Thanks! It seems this shaders_glsl is missing in my install, but I tried some other shaders and found the LCD grid (just lines) works nice for me. Also tried the nds shader, but it makes the picture to soft for my taste.

Back when I did all my retrogaming on my PC, I avoided scanlines and stuff like the devil, but now that I'm playing on an HDTV I actually find the picture and contrast to be almost painfully bright if I don't use the crt-pi shaders. Maybe it's my age?

@tonytoon You are not alone. 😀

For me scanlines are almost like "anti aliasing" for strong pixel style games.

Did somebody manage to get a nice image out of mupen64plus+Glide?

lr-Glupen (sadly it's dead) looks good, but mupen looks somewhat blurry and the aspect ratio seems off, as I described here.

Have you ever tried the video smooth option? If you haven't then you really should give it a try. The games will look way better on a HD TV. Go to the main retroarch.cfg file and enable video_smooth and set it on true. I'm surprised no one mentioned this because if you combine this with a shader it will look amazing.

@PetroRie It won't affect shaders, which control this setting independently.
