6. LCD as PC VGA,HDMI,AV,TV display TSUMV59
There are also boards available on TSUMV59 chip, this controller offers also a player from USB pendrive as source of various movie formats and pictures. It is another controller, I can call “amazing” board.
Manual for this controller is available for download at bottom of THIS SIDE .
Model: LA.MV9.P V59
TSUMV59 version lastly become quite cheap and available IN THIS SHOP
This board on picture have new updated TV tuner with R840 chip, so it use new firmware (software package must have in name “R840” ), if is used firmware for old type of board then TV tuner not works at all. With new firmware for R840, TV works surprisingly clean and nice with analog channels of cable network.
After some testing, with new firmware package, looks like this board supports a big number of screens, resolutions and LVDS types.
So that is the biggest screen support I ever seen.
It have switchable 4 aspect ratios as 4:3, 16:9, zoom1 and zoom2, so it is like a real big TV set.
To access “service menu” please open Menu and then type 1147 from remote control – that all , you are in “service menu”
You can change connected keyboard type, 7 or 5 keys in “service menu”, as is possible to change many other parameters of controller.
Firmware programming and connection of TV to controller is the same as for TSUMV29 described here 5. LCD as PC VGA,HDMI,AV,TV multifunction display
However, TSUMV59 have much better functionality.
All other inputs as PC HDMI and AV works also in the same way. Is possible to turn OFF Blue Screen for FPV modelers.
HDMI input, most useful for Raspberry PI funs, as for other hobby use, or as for external monitor for portable HD camera.
HDMI scaling 16:9 picture to the screen connected to controller even 16:10 , so geometry can be corrected by “overscan” option in “service menu”.
Remote control have more buttons as there is ability to play from USB source movies, music and pictures.
In fact, movies are played well with good sound, in some codecs player do not recognize sound track, so few movies was silent.
I tested pictures and movies using as source pendrive and 2.5″ HDD in USB case, both working well, so USB port have not problem to use HDD as movie-music-pictures source.
Programming is very simple, we must choose proper .bin file and copy it to pendrive at root directory, plug pendrive into USB, then plug power cord, status LED will made some flashes and software upgrade is done.
Two words about HDMI input, most useful for Raspberry PI funs, as for other hobbyist.
HDMI input recognize in proper way only aspect ratio 16:9 resolutions.
That means, device detect 16:9 ratio resolution and then scaling it to resolution of screen used with LVDS , so any native 16:9 resolution sent by HDMI, will be scaled to resolution of screen connected to device even not matched 16:9. That little odd but works.
So if you plan a mostly to use HDMI , look for screens with native 16:9 ratio resolution, that way you will be able to see a native resolution of HDMI 16:9 and native of screen what gives the best results in picture geometry (circle is circle not ellipse).
What if you have 16:10 screen and you are not happy with circle looking like ellipse ?
Well, there is sophisticated solution:
– SERVICE MENU – this is option for advanced users
Press MENU and type 1147 to enter into “Service Menu” , in this menu find “Overscan”, you can made picture wider (and then center) and a bit flattened (and also centered), helps using testing picture of 16:9.
So by this way is possible to get picture with proper geometry like in 16:9 native screen.
There are also many other options, if you are interested then look and test them by your self.
If you mess the settings, always you can made “factory reset”
Other practical tips of Service Menu are also in this manual
Some words about older board with old type TV tuner as on picture
It looks like older board is made typically for 16:9 and 4:3 aspect ratio screens.
There is not firmware support for other laptop’s typical 16:10 ratio screens (no support for 1280×800) .
However I was able to find firmwares for 16:10 screens, unfortunate remote control was not working with them 🙁 .
I hope to find a bigger firmware package, for particular remote control with bigger support of resolutions.
All firmwares are described as 7 key keyboards but it works also with 5 key keyboard.
You can change connected keyboard type, 7 or 5 keys, in “service menu”.
Keyboard for controller
Notice that 5 keys or 7 keys are possible to use with board so also firmware must be for 5 or 7 keys mode.
In TSUMV59 is possible to change keypad 5 or 7 keys in “service menu”.
5 keys looks not much but works really nice,
when first pressed key “<” than volume is triggered for regulation, when first pressed key “>” than channel changing is available.
Keyboard can be easily done on universal prototyping board using microswitches and wires.
Controller supports A/D type keyboard (Analog to Digital converter is used at keyboard input) , so is possible to use only two wires for 7 keys. In such case we connect only GND and K0 input for keys. That work with 7 and 5 keyboard style.
Each function is determined by proper resistor connected in series as follow :
