Hey guys! Does anyone know the output resolution of the VS2480? I'm trying to connect to a Sharp Aquos LCD TV and it isn't working. When I connect it to the sharp's PC input it recognizes that I've plugged something in, but the display shows a blank screen. I've called Sharp and they said that the Aquos has to have a "supported" resolution and to try to change the resolutions to see if I can find one that works. However, there's no way to change the resolution on the 2480. I've tried to change the refresh rates to no avail.

I called Roland and they couldn't even tell me what the output resolution was.

The guys at sharp said that the refresh rate won't matter if the resolution isn't supported...

So, anyone know what the output resolution is? If it's supported, then maybe my input on the TV isn't working...if it's not, then I'll stop trying!

Also, is it possible to use some sort of VGA to HDMI converter with the 2480?

Thanks!

Brian

640 x 480

nothing else. Don't know if a converter would work.

Good luck

Check the Utiltiy>> System parameters>> Param?? for VGA settings, you may have to set the Hertz differently, scroll thru different Hz setings from 60 to 75 and find the setting that's best, that may solve your problem.

I agree. 640 x 480 is the only resolution

I tries the various refresh rates...it made no difference...but now that I know it's 640x480, I'll call sharp back and see if that's a supported format, if so then they need to tell me why it won't work!

Good luck, it might have some thing to do with it being a TV/monitor?

I suppose it could, but it has a dedcated "PC" input that is a standard DB15 monitor plug...so I think that's what that particular input is designed for...I'll call them back and see if I can get anymore info!

Soooo...I think I'm out of luck here...Sharp says that in order to display the signal that it has to fall into one of the following categories:




I'm guessing that the horizontal frequency is off because it doesn't display anything at 60 or 75hz, and there's no way to adjust the horizontal frequency on the Roland... \:\(

According to that compatibility chart it should work with the 2480. The horizontal frequency is not a deciding factor really, it is derived from the horizontal and vertical resolution and the refresh rate.

http://myhometheater.homestead.com/bandwidthcalculator.html#anchor_13194

Even if the horizontal resolution would be different it should in theory still be able to sync (although the picture could look bad), it's mostly the vertical resolution and the refresh rate that determine compatibility as these can be determined with 100% accuracy (as they are signaled separately) while the horizontal resolution cannot (it is only the frequency with which the color/brightness signal lines are modulated).

Seems to me your monitor does not honor its own compatibily chart, unless there is some other problem. Bad cable? Broken VGA output port? Can you try it with another monitor?

I agree, the chart indicates it *should* work.


Do you have an old PC around, that you can run in 640x480, to see if that works??


What info is found on Page38??

I plugged my laptop into it with the same cable and it worked fine with that, however, the lowest output resolution I could set it to was 1024x768.

Page 38 just says that if it's a 1024x768 signal you have to go into the tv setup and set that resolution manually. It worked fine on that setting. Now, it DID NOT work with the same laptop when it was set to 1280x800 which is the laptop screens native resolution. The tv showed just a black screen as it did when connected to the roland.

I'm starting to think the Roland output isn't really 640x480...

I think I do have an old tablet pc with a docking port with VGA out, I'll try to hook that up and see what happens tonite...thanks guys!

Brian

Ok...I've found something rather interesting...

I've hooked up my old tablet pc to the Aquos and set it to 640x480, got nothing on the screen. Returned it to 800x600 which is the tablets native resolution and still nothing.

So, I went into the graphics card properties and went to monitor setup. Now, here I had the option to make the monitor (aquos) the "Primary" display. Once this was checked, the picture then appeared on the screen. Both resolutions worked fine and actually looked REALLY good!

Now, I think the problem with the Roland is that whatever the sharp needs to see (that it is the primary display) isn't being sent by the VS2480...I'm not a huge software person, so I don't know how it all works, but this seems to be the problem.

Any software guys out there have any input on this? Any way around it?

'Primary' display is a Windows internal affair and has no bearing on your problem with the combination 2480/Sharp.

I believe the 'retrace time' can vary slightly between different devices. Perhaps the retrace time used by the 2480 is just outside what the Sharp accepts. If that's the case the Sharp is being too picky.

So far that is my conclusion anyway. The 2480 outputs a perfectly good VGA signal (of course there could be something wrong with the VGA output in your unit) which should be acceptable to any display devices that claims to accept 'VGA resolution' (640x480).

Do you have some other display with a VGA (connector) input that you can test your 2480 with?

Yes, I have a small one that I currently use...like a little 12 or 13 inch deal...it displays just fine from te Roland...

I guess the Roland and sharp just aren't compatible. \:\(

It does seem odd though about the primary issue...I still think the sharp wants to see that for some reason, because the tablet was showing up on there until I changed that setting...

That primary/secondary thing is a Video Output Option on your tablet PC, it simply selects the VGA port as the "Primary" Output port. there is nothing "primary or Seconday" about the actual VGA Signal itself.

^^^ Ahh, I see, so, basically you're saying that that "enables" the VGA output to work? Ok...well then, I have no idea why it won't work with the 2480 then...as it works with both laptops I tried as long as I have them set to primary.

So, the roland works with the small LCD so I know the output is good...but the Sharp only works with the laptops and not the roland. Doesn't make sense unless the roland is outputting an unsupported resolution...which it's not supposed to be.

Are you sure you have the proper refresh rate set in the VS utilities?

I've tried all 4 of them....none of them worked. It was set to 60hz by default which is what the output of the laptop was as well and it worked there...but I tried the other three refresh rates as well...no luck...it just doesn't make any sense to me.

Even tried setting the VS to LCD from VGA, no difference.

Does the VGA output always look crisp and sharp? I connected mine to an LG monitor at 60Hz and also thru a VGA to HDMI convertor to a 30" Dell and certain parts of the text is definitely not pixel sharp. I wonder if it's the problem with the VS VGA output.

I am getting ready to dive in and work on the VS-2480. I have given it a diligent try to use my 27" beautiful iMac monitor with it, but no go, via VGA to HDMI or VGA to USB.

This is the monitor I have and currently using (I use it on a Mac Laptop when traveling):
AOC i2367Fh 23-Inch IPS Frameless LED-Lit Monitor, Full HD 1080p, 5ms, 50M:1 DCR, VGA/HDMI, Speakers, Multi Purpose Stand

It is elongated and pixelated. The VGA connection is good and everything does as it should otherwise.

I have tried refresh rate and can find nothing to adjust the elongation on the monitor.

Is there a recommendation for an inexpensive monitor that is clean and clear like the photos I've seen here. What is the recommended screen proportions, horizontally and vertically?

Always, thanks for info...

I don't have much to offer, but I would suggest using the make/model of the one pictured above and discussed previously as possibly a good guide for specs - Sony Bravia model # KDL-32L5000
You can find and check the specs in its manual, or you might have enough info to search and compare against the amazon page here - https://www.amazon.com/Sony-Bravia-KDL-32L5000-32-Inch-Black/dp/B001S2RDCM

The key may be the 720p style monitor...... I'm guessing because newer style monitors and/or settings may be beyond what the 2480 can reasonably display.

are you sure the VGA is selected on the 2480 ?
it might be set to the LCD on the 2480.
to select the VGA or LCD press the shift and utility
buttons at the same time.

It wouldn't even show on an external monitor if VGA wasn't selected, so yes it is!

I'm trying to attach a photo but can't figure out how to embed it here. It wants a HTTP address when I click on "enter a photo" icon... Can anyone direct me on that?

It actually loooks better in the photo than in person, but wanted to show it. My AOC 23" ratio is 16:9.

Is a 4:3 ideal for the 2480?

640 x 480 is 4:3
If you try to "force" the ratio to something else it will distort.
A high def display will just assign more pixels to each "dot" of the 640 x 480 output from the Roland.
You will have black areas to the sides of any screen wider than 4:3

I don't think this VS Planet server hosts images. It wants a URL address to display images hosted elsewhere.

Thank you calypso! I understand now... I would much rather have the black strips on the side than stretching to fit, which is what I have. I haven't been able to adjust it anywhere. I may look for another monitor.

Yes - as calypso has said - you need to use some cloud service to upload the picture you want to insert into your reply here. If you use something like ms onedrive, google drive, icloud, etc. or a place like photobucket - upload your image there and then use that url link to post it here. Check the inserted pic in the message preview and adjust its size so that it shows clearly without being overly large too (please...)

Looks like it is stretching the image to fill the width of the screen. If you can't adjust the aspect ratio, you'll have to live with it or find a different monitor that will allow the 4:3 to display (maybe an older model?).
You can google the monitor brand and model to see if there is a "hidden" menu to adjust aspect ratios.
