how to config portable 5 inch screen ( pics inside)

[Tick Lpsk]

i just bought waveshare 5 inch lcd screen
http://www.waveshare.net/wiki/5inch_HDMI_LCD
it worked ok. response time is good
but it does not show full screen
I've tried overscan on/off in the menu

menu work nearly perfect but left the right side

in game it's shown top left of the screen

please advice

Thanks in advance

Actually it is working as expected as this screen does not own a scaler see : https://www.adafruit.com/product/2260. You need to configure it manually in the/boot.conf.txt and force the resolution. It is described in the wiki here https://github.com/recalbox/recalbox-os/wiki/TFT5-Screen-HDMI-(EN) and here at adafruit https://learn.adafruit.com/adafruit-5-800x480-tft-hdmi-monitor-touchscreen-backpack/raspberry-pi-config

# uncomment if hdmi display is not detected and composite is being output
hdmi_force_hotplug=1

# uncomment to force a specific HDMI mode (here we are forcing 800x480!)
hdmi_group=2
hdmi_mode=1
hdmi_mode=87
hdmi_cvt=800 480 60 6 0 0 0

max_usb_current=1

thank you. i've done it
but it only fix the menu (emulation station)
but when i've try to play game
it's still the same

[ian57]

ok you'll need to modify the recalbox.conf like that :

global.videomode=default

to use the default configuration from the config.txt

[Tick Lpsk]

thank you .
It work perfectly
really appreciate

one more thing
is it possible to get rid of pink line on the left?

[ian57]

Don't know, perhaps it comes from the screen. I have this problem on a 19" lcd screen too. Need to investigate further!

[Tick Lpsk]

thank you @ian57
really appreciate

Is that line linked to the audio through hdmi ? Such things happen on DVI

[ian57]

@subs +1 my screen with this violet border is connected with HDMI-DVI cable.

[Substring]

@Tick-Lpsk which sound output are you using? You should give a try by disabling HDMI audio (please check the DVI wiki)

[Tick Lpsk]

@subs thanks a lots bro
it work great now
i take a tut from here
https://github.com/recalbox/recalbox-os/wiki/Connect-your-recalbox-to-a-DVI-screen-(EN)
no more violet line

then i wonder can you get rid of buzz sound / white noise (mostly in the menu)
when i put a headphone in. I can hear i really loud
and i already search the forum
there is no answer

[Substring]

well, the jack output is ... how to say ... awful ...

Do we need to purchase that extra part from Adafruit in order for it to work?
It covers all the GPIO and I would need that for an arcade like box for myself?

Works perfectly with all emulators except n64. Keeps crashing.

I wrote this in the Recalbox.conf

n64.videomode=default

Hello friends, thank you very much for the information has been very useful.
I paste the code in the config.txt and everything works fine except the color on the screen is not good.
Does anyone know how to change this?

[sallerin]

@ian57 hello, have the same problem with the same screen, but modify the recalbox.conf doesn't change anything (adding global.videomode=default). Have an advice? Thx

@resu @Seramis
It seems to be a known problem : http://www.robohara.com/?p=8047 and here https://retropie.org.uk/forum/topic/3191/color-issue-reds-appear-blue-etc/3, read carefully and test the proposed settings.
