My old Dell monitor fixed itself?????

[Out Of Bubblegum]

I dug my old Dell 2709W monitor out of a closet. I stopped using it years ago because it developed horizontal lines. On the right side. About 10 columns of pixels that were permanently stuck on. Different colors and not adjacent to each other. I used it a few months ago in an emergency but it still had the same lines. Because of my breaking my newest monitor, as I moaned about in another thread, I set the Dell up again. I kinda noticed that there seemed to be less stuck lines. After leaving it on a while, all the lines are gone. It works again. Very strange.

The other thing I noticed right away. How bright and the screen is compared to my newer ones. And more contrast. Pictures look more detailed even though it has less resolution. It is 1920x1200 and my newer ones are 1440. Everything is set to default. But a movie looks too bright. peoples skin seems to glow.

[_I_]

most displays set the brightness to 100% by default

as for the fixing of vertical lines, could be bad solid state caps, sometimes they work when hot or cold and not vise-versa

or maybe bad ribbon cable that worked when pinched/tweaked just enough
shake/twist it to see if it changes if you want risk it going bad again after you get a working replacement

Mine is set to 50%. I checked. Still bright.

Update on the lines. This morning they are back. But ... as the monitor warmed up, they slowly disappeared. One by one. That never happened in the past. If not bad caps, it does sound like something "loose". Maybe my moving it around moved something internally. Maybe my washing the screen pushed something back into place. Might be fixable, but I am not going to bother taking it apart. Strange that warming up never "fixed" it in the past.

My monitor (U2410) is a year or so a successor to yours but it's a 1920 x 1200 IPS like yours and it, too, is still petty darned bright at 50% brightness over a decade later. I use it daily and other than an issue relative to my revision (which I can work around in a way), it only has one actual flaw which isn't enough to prevent me from using it. Dimming brightness with age, something that is said to occur with LCDs, doesn't seem to be one of them, though. If it's dimmed, I haven't noticed.

I'm not too familiar with all of the advancements in displays in the last decade, but these somewhat older IPS were H-IPS or S-IPS (I forget which), which are different to the e-IPS that I know came right came after. I know the earlier ones supposedly weren't quite comparable in image quality to the older IPS (I recall the "e" even being referred to as "economy IPS" in those years), but again, I'm not sure how really modern ones compare. That may explain your surprise at the picture, though? As for the brightness, I only have my anecdotal experience, but maybe these ones were good at maintaining brightness over the years? More so if yours wasn't used daily between then and now like mine, which still holds brightness.

I never had a problem with lines on mine, but I got a slightly older and smaller sibling, a 2007WFP I think (I just know it's 20" IPS from the late 2000s and 1680 x 1050), for a family member many, many years ago for their first PC. It was used when I got it. The picture had a warm or "Yellow" lean compared to mine but was otherwise fine. Years later, it developed a line which I believe I was told was a thin (one or two pixel rows?) pure Blue color and was stuck that way, and I believe (may be wrong on this part) was also said to sometimes come and ago.

I had that on my newer monitor within a year of buying it. The green pixel of one column stuck on. At first it was a bright green vertical line. Then the transistor burnt out. I assume. After that it was a black line. I had it replaced since it was in warranty.
