Gph Lcd Slider

[sam fisher]

So whats the best place for the LCD slider to be for the best setting? So far I have established that:

far left = white line on the left and wavy lines


far right = darkness and scanlines

 

[Paradox]

it's different for each person there is no single best place

 

[reallynotnick]

well it is really hard to say being that there is no number for each place.


I found mine works the best just one left from the way it came.

 

[TelcoLou]

For me, it's just left of center .... heh

 

[fishybawb]

Far left = wavy lines, brighter colours
Far right = scanlines, duller colours, slight wavy lines (at the furthest right setting)

One move to the left is best for me too

I have this LCD test screen for the adjuster. I don't know how you would install this into a GP2X. If someone wanted to test this and see if it works that would be good. The MonaLisa thing is quite useless for actually seeing what you are doing. This image seems more useful as you can juge greyscale gamma and the left side of the screen is black so you can see if that line appears. The White square on black and grey is another good test for smearing.

just copy it as png to /usr/gp2x/imglcd/set_lcd.png

copy.gpu
cp /mnt/sd/set_lcd.png /usr/gp2x/imglcd/set_lcd.png

Aaaah, nice work DaveC. A vast improvement over that monalisa junk.

Thx

Why are all the screens different? Surely its the same peice of hardware so I dont get why the timings are different on all of them to the point where some people have ok screens and some have lines all over the place?

 

[Dr Cain]

Make something with alternating lines of black and white too, so the interlace effect can be seen.

 

[Squidge]

It's probably down to electrical tolerances. Eg. you can buy DACs, resistors, etc, but they all have tolerances of anything from 1% upto 15%, so every one is different.

Personally, I think GPH didn't check there electronics too carefully, some component(s) had a percentage accuracy, and they are now having to fix this with software rather than use the proper components in the first place.

Still, at least the software solution works.

 

[sam fisher]

I have no good place Also does making the white line appear damage the 2x or wear out the backlight in anyway?

 

[DaveC]

just copy it as png to /usr/gp2x/imglcd/set_lcd.png

copy.gpu
cp /mnt/sd/set_lcd.png /usr/gp2x/imglcd/set_lcd.png

​

Huh :blink:

How would someone that knows absolutely nothing about linux do it? No USB connecting as I don't want to mess with their shitty drivers that don't work. Is there a way to copy from the card to where it goes?

Copy

#!/bin/bash
cp /mnt/sd/set_lcd.png /usr/gp2x/imglcd/set_lcd.png
cd /usr/gp2x
exec ./gp2xmenu

Into a .gpu file, making sure the extensions are Unix (LF) (you can use Programmer's Notepad to do this).

 

[sam fisher]

ok put in in the root of your SD (the image) then make a script like

copy.gpu
cp /mnt/sd/set_lcd.png /usr/gp2x/imglcd/set_lcd.png

then that will write it to the appropriate place in the nand.

 

[sbock]

Or replace it with the one in a skin pack, than install the skin.
Nice picture, Dave

​

Or use sterm and just put in this line...

cp /mnt/sd/set_lcd.png /usr/gp2x/imglcd/set_lcd.png

Fuck scripts, I USE THE CONSOLE BABY. GO LINUX!

How do you do that it is in a tar.gz file? Is there a non command line way to add it?

In sterm, input this line

cp /mnt/sd/set_lcd.png /usr/gp2x/imglcd/set_lcd.png

The first picture has to be named what you named it though

 

[nickspoon]

It isn't in the skin I currently have access to (Pulsar, though at the moment I use Aurora, great skin). There are folders such as imgtestmode, imgbattery etc. You want the one that says imglcd. If there isn't one in the skin you're using, then find a skin with it. Copy setlcd.png to that folder and copy the skin to your SD. Run imgall.gpu.

Or just use a script.
