I have one LCD TV which took an impact to the screen but didnt break. But apparently it was on the border of breaking. It looks like it lost seal somewhere around the edge and lost some of the liquid fill, and there is a cluster of dead pixels in the spot of impact in the center of the screen

Anyway, this LCD tends to sorta "burn in" within under a minute of displaying a still image, but not permanently - it slowly recovers over the next few minutes. If the image is there for longer it may take longer to recover, up to a couple hours in one case. I use it as a terminal screen so dont care too much about the burn in (its not bad enough to interfer with displaying terminal text or basic OS stuff like window frames)

LCD doesn't really burn in images, if they get slight image retention, all you need to due is make the screen white for a couple of minutes to clear this up, but OLED's on the samsungs get permanent, image retention on the screen, commonly with facebook addicts you can see the logo on the upper right corner on every lighter screen...

And yes screen impacts will cause all sorts of problems, but I'm talking more real world impact free actual usage like displaying the windows tool bar all the time if they suffer any burn in because OLED screens do look impressive running but they are expensive and if they suffer burn in, I'll wait and stick to cheap or free LCD's for now...

If you display the same image that is burned in, you wont see the problem. So you mind it only when displaying something else. If so, choose the OLED screens for the applications where the image is changing and you care about its appearance on the entire area, conventional LCDs for toolbars and such

(this actually makes sense with many graphics editing tools and multiple monitor setup, where you can have a center OLED monitor for the actual image and side LCD monitors for the tools)

In my damaged monitor the retention is quite bad and long lasting, and it does feel a lot like burn in

I'm still a big CRT fan.  I own 3 PC monitors, a couple TVs and my Dad has an Amiga monitor.  They're higher refresh rate and color are quite nice compared to some of my LCDs, and just the way they work and look to me is kind of cool (one of them is a ViewSonic with a Trinitron tube).

Where I work used to have all CRT registers, but now in the last 5 or so years they only have 2 CRTs on terminals throughout the store, and they are showing their age big time.  I think they are there because the spot they are in is too small to fit and LCD but I don't know for sure.  But I sometimes go out of my way to use them, just for fun. :)

I am with LCDs, and specifically older CCFL backlight LCDs with TN (the most common type) panels. They work well and for the most part are very repairable

I got a couple CRTs, and one of them is big 21 inch one that does greater resolutions than all my LCDs, though this one is not very accurate at colors (there is a problem with the HV supply in it, which i fixed close enough to get the monitor working and usable, but the gamma is quite off)

CRTs are something that I really don't miss. Big bulky things that produced lots of heat. I think it was 2008 or 09 when I gave up the last CRT monitor I had in use. I've been recently collected some old 10base2 network stuff to get small segment to play with. I find old network technology interesting.

Speaking of old technology, I've been thinking of that DisplayWriter that I saw years ago, and just discovered I was really close to having a version of it.  The software that ran on it was later ported by IBM to the PC and called DisplayWrite.  Many years ago, a friend gave me her grandmother's old PC, which was a 1988 PC clone.  I don't remember the manufacturer but it had a compact case, similar to a baby AT, 8088 processor, 640K of RAM, dual 360K floppy drives, no hard drive, and a video card that was switchable between Hercules monochrome and CGA.  I think parallel and game ports were built into the floppy control card, and it had a serial card with dual ports.  The system included a green screen monitor, and I had an old Okidata dot matrix printer for it.  I recently found a disk image for DisplayWrite, and with this system, would have been functionally very similar to the DisplayWriter.

I'm now on the lookout for one of those electronic word processor/typewriters that used an external monochrome monitor, which were commonly sold in the 90s.

I have a couple of old 10 base media converters from copper to ST fiber, those things just don't die they have to be like 15 to 20 years old and for running a monochrome laser printer they are fast enough to handle anything thrown at them, yet I've seen several 1000 base switches fail in only a few years..

Re: Old computers? « Reply #217 on: September 28, 2017, 07:10:56 PM » Author: Flurofan96
I recently got on eBay a Fujitsu & Siemens P5925 tower PC for 17 quid plus 6.99 P&P  8) Its a certified for Windows Vista PC but the thing is that it came without Windows Vista (wouldn't touch this OS with a barge pole) but I installed Windows XP Service Pack 3 instead  8)

I use it to run old games such as Unreal Gold and also open up MS word/Office files that sometimes I need to open.

Another thing is with my Unreal Gold game I am struggling to get the right quality of graphics. I am using the video driver "Direct 3D support" and inside the game enabled the "show details" but still I can't achieve of what would you expect is in the game http://www.lighting-gallery.net/gallery/displayimage.php?pos=-136986 here is pic of what I expect to see but all that happens is crummy resolution with the fluorescent fixtures not showing their prismatic cover details. Can someone help

Graphics adapter AKA Video card (GPU) is a hardware thing that is either integrated in the motherboard or a card that plugs into a slot on the motherboard

Update: completely sorted out the graphics problem with my Unreal Gold game on my Fujitsu PC. The problem was that it had no graphics card in the motherboard's PCI slot. I however managed to install a PNY GeForce 7200 G8 GFX card from my "custom" built Mac or "Hackintosh" and after installing some drivers, the game looked so much better. Now I can play my Unreal Gold and plus more classic FPS games. I really hope to get the UT99 in to my hands

The discrete graphics adapters (connected to a slot) are more powerful than the basic integrated graphics device on the board

The integrated graphics are generally sufficient for non-gaming uses with a lightweight OS like Linux or Windows XP (and with newer computers, also with heavier OSes like Windows Vista/7/8/and above). For the low demand applications they are more reliable than discrete adapters, since they make less heat and consist of fewer components (they are built into the chipset, and they use the system RAM instead of having their own) so have less things that could fail

Here's a recently acquired oldie. A Dell Latitude C640. Boasting 2.0 ghz of CPU, 1 gig of ram, a new WiFi card and a 40 gig hard drive.

A friend gave it to me for free so I decided to fix it up and give it new parts and a brand new install of windows 2000 professional SP4.
