Connecting external monitor to Genos
« on: December 10, 2017, 04:26:02 AM »
Hello,

Last week I received my Genos. Great keyboard.

To be able to read the score on an external monitor i bought me a 'I-TEC DISPLAY ADPTER TRIO'.
This can adapt USB to VGA, HDMI or DVI. It uses the DL-195 chipset and is compatible with Yamaha Genos.
But I am not satisfied about the score screen. It is not as good as it was with my Tyros 4 and the normal VGA connection.
That the 'cursor' is not following the score is known, so that is not my issue. It's all about the look, definition, readability ...

So on another forum somebody uses a 'I-TEC USB2VGA' adapter (DL-165), and for him the screen is even better than with the Tyros serie.

My questions :
Could the used adapter be the cause of the difference  ?
Are there members who could confirm that there is a difference between adapters that are used (DL-165 , DL-195)?
I am only interested in the look of the score screen (the other screens are not important for me on the external monitor.

In another topic 'ZIONIP' has tested a few adapters and even posted some pictures.
They were looking good, but it didn't shows the score screen.

Regards
Etienne

Hi Etienne,

There is no difference in the output / scaling between the DisplayLink DL-165 and DL-195 chipsets - they are the same design with a slight difference of highest resolution each supports:
DL-165                DL-195
1600 x 1200        1920 x1200
1920 x 1080        1920 x 1080, 2048 x 1152

The display output of Genos, and PSR-S970, which I both own, is 800x480, which is supported by DL-165 and DL-195.  I have USB 2.0 display adapters with DL-165 and DL-195 and could not tell any difference on 1920x1080 external monitors for Genos.

The fact that you are not satisfied with the score screen is due to the scaling of 800x480 display output of Genos to your external 1920x1080 display.  You like the way how your Tyros 4 scaled 800x480 to 1920x1080, but do not like how your Genos scaled 800x480 to 1920x1080, whereas the guy in the other forum likes how Genos scales its external display output better than the Tyros.

I do not own any Tyros before, so I assume the Tyros resolution of external display output is also 800x480.

Since we cannot change the way how Genos scales its 800x480 resolution to 1920x1080 external display resolution, I ran some tests on 2 different external monitors using the same Plugable USB 2.0 to VGA/DVI/HDMI display adapter (DL-165) to see how these monitors handle the 800x480 video output of Genos.

I had a Dell S2240T 21.5-Inch touch screen monitor on the music stand of Genos, and a LG 24MP88HV-S 24-Inch IPS monitor on a standalone heavy duty music stand just above the Dell monitor:

I selected a MIDI song "Bridge over troubled water" on Genos, here is the 800x480 screen captured directly on Genos:

Here is the picture I took on the Dell monitor:

Here is the picture I took on the LG monitor:

There are some subtle differences on how these 2 monitor handle the 800x480 resolution video input from Genos, but they are so small that we can simply ignore them and assume them to be identical.

As a comparison, I loaded the same MIDI song on PSR-S970, which has screen display very similar to the Tyros.

Here is the 800x480 screen captured directly on the S970:

Here is how the LG monitor displayed the 800x480 resolution video output of the S970:

I compared the score outputs of the Genos and the S970 and found that the score output scaling on the S970 is slightly smoother than the Genos, with slightly less noticeable jaggedness.  The slightly meatier fonts on S970 also helps the output to be slightly smoother in appearance than the thinner fonts used on the Genos.

I hope the above answered your questions.  You can contact Yamaha customer support about your dissatisfaction on the Genos score screen display and request for better on-screen score presentation.

You might also want to explore the possibility of using your Genos to display score using external apps like SongBook+ on iPad Pro 12.9, or similar app(s) on Android tablets, with score in PDFs instead of MIDI files.

Thanks,
Paul

I found that Genos only supports one external display, even when multiple USB 2.0 display adapters are connected to Genos, depending on which USB 2.0 display adapter got recognized by Genos first.  In my tests, the Plugable USB 2.0 display adapter with HDMI connection got recognized by the Genos before the StarTech USB 2.0 to VGA adapter did.

To connect more than one external display to Genos, the Genos USB 2.0 display adapter outputs to a HDMI splitter / distributor / matrix switch, through which multiple external display monitors can be connected.

Paul,

Thanks a lot for all these tests.
I can see that the result on a S970 is better than on a Genos.
What is the initial screen resolution of the internal S970 screen ? They don't mention it in the manual.

Another question :
On the Genos external monitor the 'cursor (red ball)' is not moving, does it on the S970 external monitor ?

Regards
Etienne

Hi Etienne,

The screen resolution of S970 built-in screen and external display output is 800x480.

On P. 130 of PSR-S970 / PSR-S770 Digital Workstation Reference Manual:
https://usa.yamaha.com/files/download/other_assets/2/437562/psrs970_en_rm_b0.pdf
"If you want to use an original picture, prepare the desired file (a bitmap
“.BMP” file no greater than 800 x 480 pixels) in the USB flash drive . . ."

The jumping red dot of the score screen on the S970 external display works:

Thanks again Paul,

The fact that the jumping red dot works on the S970 makee me think that there must be an error in the Genos software from Yamaha.
I hope they will soon fix this.

Etienne

I do not own any Tyros before, so I assume the Tyros resolution of external display output is also 800x480.

The display resolution on all the Tyros models is actually 640 x 480, not 800 x 480.

This may account for the difference between the Tyros and Genos displays that Etienne is noticing when they have been scaled.

You are right, Ian.

I found this on P. 118 on Tyros5 owner's manual:
640 x 480 dots TFT VGA color 7.5 inch LCD

Thanks,
Paul
