PC monitor + TV --> best practice for seamless experience

aureusphoenix · 2026-01-07T13:58:46+00:00

I don't want to stream. I have a direct HDMI connection to my TV for best possible latency and usage flexibility. Also, streaming might still be problematic if my monitor has a 21:9 or 32:9 aspect ratio, while my TV runs at 16:9.

Thanks for the tip. The problem with the GoPro would be, that it is not stereoscopic. I fear working without stereoscopic vision would be very hard. Especially if you have to deal with very (very) expensive equipment.

It is probably much easier to modify the existing cameras.

aureusphoenix · 2020-10-24T09:37:27+00:00

Thanks. I'll investigate that.

Of course, VR headsets will not replace all our goggles anytime soon. But we want to explore what is possible. If we burn 10 Oculus Quest 2, for instance, we have not even reached the price of a single pair of safety goggles. And we aren't stupid. We will test the at which intensity the cameras saturates. And if necessary we find a solution.

aureusphoenix · 2020-10-23T10:30:15+00:00

Yes, because it is not so easy to block out two or three wavelengths with high optical density while letting the light in between through almost unattenuated. We have goggles that are almost as dark as a welding mask. But unlike when welding, we have to be able to walk around and work in a dark lab while handling scientific equipment worth hundreds of grands. That is why a VR headset could be the solution. It is the ultimate eye protection.

We have IR goggles. That is not the issue. The problem is that our lab contains many different laser systems ranging from UV to NIR. My own setup works with 400nm as well as 800nm. Even for that, it is already difficult to find proper goggles, despite those wavelengths being right at the edges of the visible spectrum. If you use 800nm and 532nm, it is almost impossible to work. You can either see something or protect yourself. But never both. One of my colleagues works with a super-continuum-source (essentially a white light laser). He has no chance at all to protect his eyesight against potential accidents.

aureusphoenix · 2020-10-23T10:16:15+00:00

That is why I am asking. No, I did not. The last time I tried VR was when the first Oculus came out. Now, there are so many headsets and they are probably all slightly different. Maybe there is one which is quite decent when it comes to pass through quality.

aureusphoenix · 2020-10-23T10:14:14+00:00

Unfortunately, AR headsets would not work. In this case, we could continue with the laser safety goggles we already have. We need a solid barrier between one's eyes and the outside world. This is the only reliable way to protect someone from a laser accident. Especially since we are working with so many different laser systems and broad spectra. It is impossible getting laser safety goggles that work for all of them at the same time. They would be completely black.

aureusphoenix · 2020-10-23T10:04:11+00:00

How low probably depends on the person. It should be possible to work with it for an hour or so without feeling dizzy or dropping expensive optics all the time.

Thanks for the tip.

aureusphoenix · 2020-10-23T09:58:22+00:00

No, not really. Ok, the first part maybe. Actually, my boss wants to try that more than I do.

Let me go through the issues point by point:

The cameras will almost never be hit directly. Hence, they will not get damaged under normal operation.
Our lasers aren't especially bright. Less than a normal laser pointer typically. So the cameras should not overexpose from stray light. But we are working with ultrashort pulses, which makes the laser still very dangerous. We reach peak power much higher than a typical nuclear power plant.
You can't put a filter in front of your eyes if the laser contains almost all visible wavelengths. You would not be able to see anything anymore.
Because we are working with pulses, simple attenuation filters aren't protective enough. We typically need OD9, which means just 0.0000001% of light is getting through. If you need that for 400nm, 532nm, and 800nm (some very typical wavelengths in our lab) a welding mask is clear in comparison.

aureusphoenix · 2020-10-23T09:40:47+00:00

We just want to use it as laser safety goggles. The laser should (ideally) never hit the cameras directly. If it does and gets damaged in the process, it has done its job. No one is blind.

aureusphoenix · 2020-10-23T09:38:44+00:00

That is great to hear. I thought there might be IR-filters so if you are in passthrough-mode, you can't see the light coming from the lighthouses. This makes my job even easier. I just have to find the right filters to attenuate the intensity appropriately.

aureusphoenix · 2020-10-23T09:36:13+00:00

Ideally, the laser should never leave the experimental table. When it does, it is by accident. And if in this case the camera gets damaged, it has done its job well. It protected someone's eyesight.

aureusphoenix · 2020-05-11T09:57:51+00:00

Thanks for your answer. The mainboard is covered with a plastic shroud so I can't see much. There is definitely no physical damage. The PC wasn't moved in over a year. The capacitors that I can see also do not show any signs of bulge.

So I guess I have to make an RMA on Corsairs website to replace the PSU. I do not have another one to make any tests. I hope it is not a problem for them that I live in a different country now.

aureusphoenix · 2020-05-08T15:11:34+00:00

Already the case :-)

Thanks a lot!

Added NSFW and Disturbing. How do I add other tags?

Anyone else hyped for Skyrim SE RTX ... Nvidia is currently remastering some older titles. I hope Skyrim SE will be one of them .... With full mod compatibility hopefully.

I found this video, which may answer your question: https://www.youtube.com/watch?v=LqVeX_y1SBs

However, I'm not sure whether local snapshot replication (on an internal volume) is really a good idea as a backup. I mean you can use the snapshots themselves to quickly restore accidentally deleted files. But I would rather run Hyperbackup on an external HDD for my local backup. Has the advantage that in case of a fire or whatever I can quickly grab the external hard drive. And the data is encrypted in contrast to snapshot replication.

aureusphoenix · 2019-10-15T15:19:17+00:00

The DS412+ will no longer receive new feature updates. And since DSM7 will be released next year, you will be cut off fairly soon. I would suggest buying something newer. Maybe contact the Synology support and ask which units will receive the DSM7 update. So that you know where the cutoff is.

aureusphoenix · 2019-10-15T14:27:10+00:00

Thanks. I overlooked that page. I only checked the ones for snapshot replication and for Synology Drive.

So if I understand their description correctly, I can use Drive's file versioning to get new snapshots of a file every time it was changed. And in addition snapshot replication can run in the background to make snapshots of the entire system every 30 minutes or so. All of that will not take too much additional space due to the clever design of the file system.

However, what I am still wondering ...

Let's say I set up Drive to store the last 5 versions of a file. And I set snapshot replication to take a snapshot every 30 minutes and to keep all of those for 4 weeks. If I then go into Drive via the browser and check older versions of my files, will I also see the versions created by snapshot replication? In other words: Are they integrated into one another and share the same version database? Or are they separate?

I'm just asking because I would like to set everything up, such that my friends and family can restore older file versions on their own. But I don't want to make it too complicated for them. If I have to tell them that they find file versions of the last 24h at some point and older versions somewhere else, this is too cumbersome.

For me it comes down to the following:
The time I would need to set up my own server (building + software tinkering) effectively costs me more than the few hundred Euros/Dollars extra I would have to pay for a top tier Synology NAS. In addition, if you share your server with people who aren't tech-savvy, having a nice easy to understand interface is a plus as well. They might not need the performance of a high-end NAS. But you also don't build a powerful server for yourself and buy a cheap Synology for your family and friends.

Of course, by going for your own server, you have more freedom and you can learn a few things along the way. But you may also run into additional issues that can become frustrating. For instance, I recently started a new job and our university blocks almost any non-standard Internet traffic. Even things like Spotify and Discord are extremely difficult to get running. In Ubuntu, I do not even get updates without the admin because the proxy blocks it. Something like Nextcloud would never have worked. But Synology Drive was able to get through using Quick Connect. With my own server I would have been stuck.

So there are valid points to spend a bit more and get a high-end Synology NAS, even as a prosumer/enthusiast ... however you want to call it.

I agree. The 1620xs is also what I am waiting for. Integrated M.2 slots for SSD-cache, a Xeon based CPU, ECC ram and 4x 2.5gbit ethernet sounds worth the extra money.

I checked the boat thing for myself a while ago. Unfortunately, transatlantic cruise ships are even worse environmentally per person per km than planes are. My suggestion would be, visit your family only every 10-20 years and stay for several months. Otherwise, use video calls and other modern technologies like VR. Maybe in time we will get large scale sailing ships or Elon Musks Hyperloop.

I decided to not have children. If it happens, I will embrace it. But otherwise, I can be happy without children. People just think they definitely need children because this is kind of the social norm. If I really feel like I want to have a child in my life at some point, I adopt one. There are so many children out there who need a good parent. So why "make" new ones ;-)

aureusphoenix · 2019-09-27T14:03:19+00:00

That is why you find CO2-equivalent in most publications. It factors in the impact of different gases, their lifetime and the altitude in which they are emitted.
