Odd Image Display Issue

[Bristolian]

Howdy learned folks, I'm wondering if anyone can help with a problem I'm having when trying to display images on my television?

I have something like 16,000 edited images (a mixture of jpg and tif formats) stored in a shared Photos folder on my Synology DS220j NAS and on a removable Seagate USB drive. The images are saved in folders by date and place/event/interest (e.g. 20210924 - Osborne House) and the structure and content on the Seagate drive is an exact copy of the NAS. The NAS is connected to the TV by Ethernet cable via our VM modem/router. This arrangement was working fine until recently and I'm not aware of any updates/changes that coincide with the onset of the problem.

So here is the problem: when I select the NAS as the source for the images on the TV the picture that is displayed is very poor quality and the TV reports the image as having a very low pixel count (e.g. 640x426). I suspect it is displaying the embedded thumbnail rather than the full image. On any other device (i.e. PC, laptop, iPad, iPhone, etc.) the pictures display properly at full resolution.

This would (to my mind) suggest that the TV is the problem but when I select the Seagate drive as the source (directly connected to the TV via a USB port) the pictures display properly at full resolution.

I have changed Ethernet cables and moved them to different router ports to eliminate them as the source of the problem and am now scratching my head.

Any ideas, folks?

I agree that it sounds like you are seeing an embedded version and not the actual image... like the TV is viewing the images in an "explorer/finder" type window rather than opening the actual images. I suppose it might be doing that because it sees the NAS as a separate device rather than just storage/drive... sometimes there is an option as to how an attached device is treated. Or maybe it doesn't like the routing naming convention (multiple levels deep).

Is your TV (or router) smart enough to update itself when attached to the internet? A lot of them are these days, and they often do not ask if you want them to (default is set to auto update). If so, that could explain the change in behavior...

Hi Steven,

Thanks for your thoughts. The router certainly can (and does) update itself without any warning or option not to do it. Normally this is done in the early hours and I have seen it happen so that might be one possibility. I don't think the TV can but maybe it's more capable than I give it credit for. It's a Panasonic TX-49FX700B and only two years old.

I did install the new version of the NAS operating system but this was working okay after that.

I'll work my way through the TVs network setting again later tonight to see if I missed something the last xx times that I have done that
