1. Screen orientation
You can choose landscape, portrait, or reverse landscape screen orientation.2. Screen ratio
You can choose stretched to full screen, 4:3 real PSX ratio, or widescreen mode.3. Screen color Depth
You can choose 16/32 bit colors. Colors will be better in 32bits in MDEC videos.4. Top/bottoms black bands
Top/bottoms black bands. You can remove the top/bottom black bands in the PAL games, getting more bigger image - which is stretched, but it can break some games (like Alundra 2 videos and loading screens).5. VR Modes
Support for different modes using google cardboard.6. Video Renderer
You can select Hardware, FXAA, software renderer or OpenGL Plugin. In general you should choose the Hardware renderer (faster and smoother graphics), FXAA is more CPU/GPU demanding but you will get smoother images, and the OpenGL Plugin is the smoothest but compatibility is limited. Use the software renderer only in very old devices (for example with GPU Adreno 200 such as Dell Streak 5').7. Internal Resolution
You can select x1/x2. x1 is PS1 resolution, x2 increase the resolution. x1 is more accurate, x2 smoother graphics, but a fast CPU is required.8. Video Filtering
You can enable/disable the filtering in the hw renderer (not supported on software renderer and the opengl plugin include its own filtering options). By default the graphics will be filtered, but if you prefer graphics more similar to real PSX you can disable it.9. Video Filtering 2D
You can enable/disable the 2D filtering in the hw renderer. It will improve the graphics in 2D games, with 2xsai and other filters.10. HW/SW Threading mode
You can enable/disable the threading mode. Threading mode is recommend in CPU 1.5ghz or less (but dual/quad core is required). Disabling this option to improve accuracy.11. GPU Plugin (read more below)
Select a external gpu plugin to use. You have to choose video renderer=opengl. In the top/right coreder there is a button to download the lastest plugin version.12. Plugin Subpixel Precision
You can enable/disable. It will improve the 3D preccision (known as gte accuracy hack in PC), but it will require a lot of memory and and fast CPU.13. Plugin Reduce Internal Resolution
You can select full resolution/480p/600p. It reduces the rendering size, important in devices with low fill ratio as Ouya or Nexus 10.14. Plugin Texture Mode
You can select enable/disable. It is not supported in some old devices, but it will improve performance in Adreno GPUs.Black Screen Epsxe
At this time, the issue is separate from GameEX. I have an unusual issue with ePSXe 1.9.25. The attached settings work fine on my main computer with a regular monitor via DVI cable. Everything is rendered fine with full screen video output. When I added this to my other computer (Alienware. solvedhelp with getting fullscreen epsxe centered hm. Anyone know how to have a program go full screen centered? - or encase it in another program or such? - i have epsxe and i got custom shaders to work with it - now i just need to get it centered so it could be 4:3 on my widescreen monitor - if i use 1200 x 900, it just stays on one side.
