Dex connection help - Samsung Galaxy Note 8 Accessories

So my free Dex has finally arrived. Trying to connect it to my Dell 2007WFP monitor to save buying a second screen. Got a full 1080p HDMI to VGA Video Converter Adapter Cable Male to Male D-SUB 15 Pin M/M Full 1080P with 3.5mm Audio Output One-way Signal Converter-1.8m/6f as the monitor can switch between two feeds, BUT...
I get the error message - Input signal out of range, change the setting to 1680 1050 60Hz but it's already at that. I've also tried updating my graphics card driver.
Any help appreciated :fingers-crossed:

HDMI to VGA adapter will not communicate properly the supported refresh rates through the analog interface of the VGA side, and your monitor thinks it's been set to a higher scanning frequency than it supports. The video output of the DeX is not supporting many modes. What about DVI? are you using that already with your pc?

Looks like my old Dell won't allow any higher and yes the DVI is used by PC.
Looks like a new monitor is required so the free DEX is not so free

Non HDMI TV use.... Q's and hopefully answers.,

Ok I'd like to know if an HDMI to composite converter will work with chromecast...?? And I have some answers.
An HDMI to VGA converter . i can confirm that definitely DOES NOT work.
An HDMI to composite (cvbs) converter DOES work. I have one of the cheap small square white ones you see a lot with phono audio outputs and the yellow av out. it requires USB power to give me a signal so sorting out 2 USB ports for use with a CC is a minor pain.
Picture quality is clearly not close to Hdmi , think 'fuzzy'. but on our lcd, with a boost of saturation, noise reduction etc watching material is perfectly acceptable. Sound seems good as I'd expect.
Problem is our TV has HDMI but no hdcp (dont ask) rendering it mostly useless and new TV is not on the cards yet, so this has helped.

Taa, however not super helpful as there's only one post with a definitive 'yes it works' not specifying what was being used, rest is conjecture and fluff. But positive signs.
Consider this the fluff-free thread on all non HDMI solutions
Have Ordered HDMI to composite so will update on success and type of unit.

Calrad makes an HDMI to Component video adaptor that should work for you, providing your TV has component video inputs. part number is 40289. It should cost around $179 retail though, so my recommendation would be to take the $150 and invest in a newer TV!
I have a Chromecast connected to an old Sony 20-inch 4:3 (not widescreen) tube standard definition TV with only S-Video and Composite inputs.
Here's how mine is connected:
Chromecast
HDMI to HDfury2 Component (bought for I forget... more than $100 a long while ago, from a previous setup)
Component to AVT-3190 HD/VGA to Component/S-Video/Composite down converter (bought for $119 used on eBay)
S-Video to TV
Audio (analog) to TV
Both the HDfury and Chromecast require USB power, but I have them both connected to an iGo MicroJuice power adapter that has 2 USB outputs ($9.99 from Best Buy clearance).
The down converter has a wall wart too, so it's 2 power plugs.
Result:
Video
It's a bit fuzzy, but what do you expect for 720p/1080p being downconverted to 480i?
Aspect ratio is correct, because the AVT-3190 down converter has switchable aspect ratio conversion (ARC), so not only is my video downscaled to 480i, it's also being letterboxed, so the vertical resolution is even less than 480i for widescreen casts. This wouldn't be a problem if you have a widescreen display.
Audio
Is fine. I'm getting analog output from the HDfury2. It also has optical digital output, but I haven't tried it as I'm just using the TV speakers.
What doesn't work:
Automatic power/input control via HDMI-CEC. Obviously this doesn't work because HDMI-CEC isn't supported by the HDfury2 as there's no way to translate that into its just video and audio output.
Given that this is about $200+ of gear to make a $35 device work, it's probably not smart. But my case is special, and I'm sure there are others with special cases as well (projectors, in-wall displays, etc), so there you go.
If you have a HD-capable display that just lacks an HDMI input, you would just need the HDfury2, not the down scaler, so that cuts the cost in half. That's how Chromecast works with my old HD projector.

DEX connectivity

I red one review that Samsung adaptor to USB C to HDMI supports 1080 resolution however any other 3rd party will do 720 resolution.
Is this true? I dont see how any modern adaptor can be restricted to 720 only?
I have a Startech.com adapter that works just find. My only issue is that when I pair my Microsoft Surface Arc Touch SE bluetooth mouse, it does not work, even though it is paired. Using the Note 9 as a touchpad works, but it cuts out from time to time in regards to registering my movement.
I get 1080p resolution when I connected through a generic type c hub. There's a greyed out option for 2560*1440 though.
Can anyone confirm the samsung dex dongle provides 2560x1440? If it doesn't, I'll just buy a generic one.
Anyone else have issues connecting certain mice to this phone via bluetooth? Kind of bummed my Arc Touch mouse won't work (pairs but shows as a keyboard and not a mouse), especially since it fits in my padfolio better.

Desktop mode with poor resolution

When connecting in desktop mode to my TV LG full HD, I see icon too big but I'm not able to upload here the screenshot. I cannot find any possibility to change it into the settings.
Can anybody experienced same issue?
Thanks

I ran into that problem with a cheaper generic monitor and a cheap adapter. At first, I had the cheap XtremePro (generic from Amazon) and sometimes my monitior showed 480p, sometimes it was 1080p. It was weird, I had to plug it in the Samsung TV (1080p) and then go back to my monitor, it would correctly show as 1080p. When I changed the generic monitor to a Samsung, now it shows 1080p. But the adapter didn't allow me to plug it in and recharge my phone so I went out and bought a new adapter that does a great job.. recharges phone AND shows 1080p.

LG monitor, depends on the age, sometimes it doesn't read the phone very well or it could be the adapter itself. Upgrade the adapter to the one I recommended before changing the monitor.
Bought one and used it on Samsung curved monitor 28" everything is perfect 1080p signal.. Maybe as said it's the Adapter. Mine come with USB hdmi and USB c ports. Or maybe some configuration on TV ? Did u try on a monitor?
Mine I was able to charge and use the hdmi in the same time...
Today I made additional test. The result is that with 2 adapters, 2 TVs (Samsung and!LG) and 2 hdmi cables the resolution is always poor if I connect thru hdmi (icons are very big) with all combination adapter+cable+TV. But if I use a vga cable (one adapter has both ports), it works perfectly.
It seems a problem on p20 pro hdmi management.

Chromecast 3 (2018)

Hi everyone!
Does anyone knows a method (either hardware or software) to force the Chromecast to output at 720p?
Background:
I have a DVI monitor and I used a simple HDMI to DVI adapter to plug my laptop in it.
My laptop died and I decided to use a Chromecast and my phone as a replacement.
After the Chromecast arrived and I plugged it in, I turned on screen mirror and hooked my kb/m to the phone and everything, only to realize that the sound was also being streamed to the Chromecast.
Needless to say that my monitor doesn't have audio output.
So I got one of those HDMI audio diverter to draw the audio and feed it to my audio system, so far so good.
I used my laptop to game was well, so after starting some withdraw from games, I decided to grab my PS2 console and got on of those PS2 to HDMI dongles and play some old-school games, then I started facing an issue: swapping cables.
To fix that I got one of those 3 port HDMI hubs and plugged both devices to it.
However the monitor is 720p, the HDMI audio diverter knows that and replicates this information to it's input port which makes the Chromecast display in 720p.
But the hub does not, it report it's 1080p making the Chromecast send 1080p video signal and the display only shows a black screen because of it not knowing how to deal with that.
So if there's a way to force the Chromecast to display in 720p it would be my salvation.
So if anyone out there knows any possible solution, please, I would be really grateful.
Thanks everyone!

Unsupported TV?

Hi guys
I got a little big issue with dex and my TV, My TV is FHD , when I connect my S20 FE wirelessly to my TV and bring up dex, The output is FHD
But when I connect it uGreen Type-C to HDMI, Dex says that the monitor/tv resolution is not supported by dex, and the output is 1366x768.
I thought the cable has issue, and tested it on a samsung monitor, and works perfectly on FHD, so the cable is OK.
May anyone please help me with this issue ?!
check the settings on your TV, maybe there are different input settings for HDMI or one of your ports is different from the others. google your TV's model and the phrase HDMI resolution etc.

Hi , I did that all hdmi ports are FHD , and tested them with my laptop hdmi, all of them shows FHD. I think dex uses a special standard , that my tv cant support it.
Samsung DeX HDMI max resolution is only FullHD (1920x1080)
I’ve got Plugable UD-CAM dock and it works perfectly fine with my Dell Latitude 7480 laptop and USB, Ethernet and WQHD (2560 x 1440) Dell monitor. Pretty much the same is applicable to my Samsung Galaxy S9 with only 1 exception - HDMI resolutions above FullHD (i.e. 1920x1080) are grayed-out in...
