Monitor error: out of range

[CharlotteSwiss]

Hi,
I got a digital microscope (AD407) which has HDMI output to an external monitor.
I have an unused monitor in stock (Viewsonic vx2255) which has the DVI input; I took a DVI to HDMI adapter and ok I can connect it, it just doesn't show me the microscope image, but it makes the error "out of range" (see image). Then I have another 22 '' monitor (Dell 2209) that I use with a desktop PC, always with a DVI port and if I connect it to the microscope I can see the image very well.
I can't understand why with the Viewsonic monitor it doesn't allow me to see the image coming from the AD407. Any olution? Maybe if I entered from the VGA port of the monitor (VGA-HDMI adapter which I don't have) I could solve it?
Thanks
Char

When connected to the Dell, what resolution and frequencies does it show?

When connected to the Dell, what resolution and frequencies does it show?

when I connect the microscope to the 22 '' Dell (HDMI cable> HDMI to DVI adapter). immediately shows me the image on the big monitor, without any information. In the images below, the Dell screen view and the Dell menu (it only says 1080 resolution, I think it refers to the hdmi cable used).
Thanks for any help 

note: both monitors (Dell and Viewsonic) have a recommended resolution of 1680x1050

I just looked at the Viewsonic vx2255 monitor manual (image below); if we look at the input frequency range, the ones it shows me on the display are included, it seems to me (H: 37Khz and V:60Hz). But perhaps the resolution of the AD407 display (you don't find much about it ...) is perhaps not supported by this monitor?
I'm sorry to have this monitor collecting dust, and not being able to use it now that I would need it ...

The AD407 video output UHD 2880X2160 24FPS; FHD1920X1080 60FPS/30FPS,HD1280X720 120FPS,.  The Viewsonic 2255 doesn't support any of those resolutions . The Dell likely supports a wider range of resolutions. I tried to find the supported resolutions of the Dell but apparently it seems to be some kind of secret .
 
Viewsonic 2255
Resolution Recommended and supported
1680 x 1050 @ 60 Hz
1600 x 1200 @ 60 Hz
1400 x 1050 @ 60 Hz
1400 x 900 @ 60 Hz
1280 x 1024 @ 60, 75 Hz
1024 x 768 @ 60, 70, 75 Hz
800 x 600 @ 56, 60, 75 Hz
640 x 480 @ 60, 75 Hz
720 x 400 @ 70 Hz

720 x 400 @ 70 Hz

also I have not found the resolutions accepted by the dell 2209, but probable that it can receive HD1280X720 (the other 3 is impossible, it has fewer lines both horizontal and vertical). However, I thought that the viewsonic could adapt the image anyway, I would have given it a second life to this monitor. At this point I think it is impossible to be able to visualize the output of the AD407 on the 2255 viewsonic, if there is perhaps a way to resize the image to one of the accepted resolutions, before it reaches the monitor. But I'm not capable.
Quite disappointed.
Thanks anyway

You should be able to see an actual resolution somewhere in the menu of monitor. I suspect that Dell accepts 1080p and downscales it.
Edit: actual resolution is shown as you open the menu in the bottom left corner.

One thing to consider is that while DVI and HDMI are the same protocol HDMI only supports a subset of all the resolutions.
It's pretty common for an HDMI monitor to not bother to support lower resolutions like 320x240 etc.

In this case it's a DVI monitor driven by an HDMI output.

It's probably what wrapper says. It shouldn't happen, because the monitor surely has DDC ROM in it and the device should query its capabilities before setting output resolution, but what the heck.

thanks guys for the help 

-wraper: you saw right, in the Dell menu it informs me that the resolution is 1080 (but this monitor has only 1050 vertical lines); as you said, however, accept to scale the image, which the viewsonic does not do! 

-psi: the viewsonic monitor has DVI input (and vga...), I added a DVI-HDMI adapter, but it is not serviced at all (on the Dell it worked) 

-magic: in fact I would have thought that on any external monitor I could have seen the image of the microscope, but obviously this is not the case; I cannot however adjust any parameter on the AD407 relating to the video output (there are only adjustments on the video resolutions to be saved on the sd card, or a 50 / 60Hz setting that I did not understand what it refers to, but I do not solve anything). 

I must admit that when I got the AD407 microscope I had taken into account that I had this unused 22 '' viewsonic monitor to use.
The fact that I can't, makes me spin the so-called (which I don't have ...)

The monitor's edid has all the resolutions and scan frequencies supported. There are various programs, Windows and Linux, to read the edid. HDMI is pin-for-pin DVI-D + sound. Devices that use HDMI typically operate at higher resolutions, but HDMI can carry any resolution up to a certain limit.

I have a 1200x1600_60 monitor driven by a laptop with HDMI out. I use an adapter HDMI TO DVI-D, WHICH is what the monitor is.

I wish I could make it all work out for you. But it's only a monitor, not like a girlfriend or something serious. Or, if you're my younger brother, then your computer is your girlfriend too! He is such a loser!

But here it is not a question of PC to monitor, but of microscope to monitor, no software can help. Unfortunately this Viewsonic does not accept the image from the microscope. If the monitor had been fullhd it would have accepted it, but being a 1600-1200 native it has some problems, which the Dell does not have. I wanted to give this monitor a shot of life, but it refused. It will remain to gather dust in the attic.
