;) I've attached another very simple 'scanline' shader, based on lcd3x. I don't think it's quite as good as the 'zfast_lcd' one I posted earlier, but this shader has the benefit that it scales well on low resolution screens (i.e. 720p).

Can you modiefied

Same as before i try modified it
Look like this better that before but dot pixel are bigger...

By replacing PI with 2.0, you've just changed the 'scanline' spacing. This doesn't fix the problem... Look at how the lines become more uneven as you go towards the right/bottom of the screen: this is ...

Oops... OK, I can see where that went wrong...

Please try the new attached version!

Can u overlook what can fix

If the shader failed to compile, I think there should be a log file in your shaders directory - probably called lcd3x_highp.log (or maybe just lcd3x.log). If you post the contents of this, I might be able to see what went wrong... (but I don't anticipate having much luck...) :(


In lcd3x.log

Unfortunately, It looks like the GPU in your tablet has floating point precision issues that can't really be fixed (unless there's a firmware/OS update, or something...). This means that all shaders are going to have rendering problems, particularly those that draw scanlines or grids. This is sad ...

For that you can use no shaders at all and no high resolution rendering

That true but it will look worst without antialiasing...the lcd3x provide more look like ds lcd screen without pixel look... if someone dont find solution for lcd3x i think i will give up using that...thanks...

Oh... I could be wrong, but that looks like a GPU floating point precision issue... (Android devices can be really bad when it comes to this - it affects many, many shaders in RetroArch, too)

Try the attached version of lcd3x - it just forces 'highp' precision (it will require more GPU power ...

Thanks
I know....but can someone modiefied it to make it working on my dispLy resolution... i just want to play using this shader or lcd3x shader only but those not working i hope someone can help...


As SSUPII said, the zfast_lcd shader won't work properly on your device because of its ...

I hope you can fix it on samsung tab a6 2017 because not working properly on it only for landscape and not for portait.....

Try playing around with the graphics settings. Also if you are trying to use "zfast_lcd" (As you quoted who made the port of it), the person who posted it said that that ...
