Josh Lyman posted:I have a 27" 1080p Acer CCFL LCD (H274HL) that, in the past few months, has started making a faint high pitch whining sound when the screen is all black. The sound becomes fainter and lower pitched when only half the screen is black and goes away with a non-black image. This is usually one of the coils in the inverter circuitry making that buzzing noise. It happens when PWM power is being supplied to the lamps. If you increase brightness to 100%, it goes away, right? At point, straight DC power is being applied, as no PWM regulation is needed to reduce power. What I think is going on is you have some sort of auto-dimming feature enabled on your monitor that tries to improve black levels by lowering the backlight on darker images, and when this happens, the PWM signal is such that circuit board component in question starts buzzing (most likely an inductor coil on the inverter board). I don't take this as a sign of impending failure. I've seen monitors with backlight noises keep running for the better part of a decade.

I find that other than the power button...the other buttons don't do anything. My brightness buttons do work, but in very, very, very small increments. My built in speaker is total garbage though, and never even bothered testing out the VOLUME buttonos.

Yup, the buttons being lol are one reason it's so cheap and why it's overclockable with low lag - there's no hardware to draw an OSD. The buttons do work, just in small increments and don't display anything to indicate they're changing. One or two buttons straight up don't do anything. Power and brightness are all you should worry about.

The LG seems to fluctuate a bit in price based off of my time spent considering buying one. I eventually went with the AOC and can say aside from the bum displayport cable that came with it, I have been very happy with it. The stand is far better than the LG. Best buy will help finance the AOC for you if that's your thing too.

I need a 22" 1680x1050 to match my current monitor, because my desktop setup is weird and I can't really fit bigger monitors on it and my desk isn't going anywhere. http://accessories.us.dell.com/sna/productdetail.aspx?c=us&l=en&s=bsd&cs=04&sku=320-9704 Is there anything wrong with the P2213? The main things I care about are that I can raise/lower/turn the monitor (i know, what a fascinating feature) and that it's the above size, and doesn't look like poo poo. I do gaming but I mostly just want a second monitor to read irc/watch netflix/etc. while I play in the primary monitor. Both this and my current monitor are 60hz anyway. I have a 560ti so I know this is compatible. I'll probably end up swapping my old monitor to the 'read/watch' role because this is newer and nicer.

That pcmonitors icc profile instructions discuss how games often ignore the profile and you'd need to setup some sort of 'default profile' to switch to if you use icc profiles and gaming with this monitor. I skipped the icc profile thing because that sounds like a hassle, but is this maybe what you're running into? Desktop/internet looking great but games looking worse/washed out? Or is it all the time? I played some Talos Principle last night and didn't notice this gamma washout you described. edit: for the record I'm just regurgitating things I read from amazon reviews and that pcmonitor site, I really don't know the technical side of things, but I'm not noticing what you're describing. I upgraded from a relatively crappy LCD screen which had backlight leakage and wasn't tiltable or height adjustable so this monitor is a massive major upgrade for computer quality of life for me, the massiveness of the upgrade could be blinding me temporarily from some of these minor things mr. nobody fucked around with this message at 16:55 on Apr 12, 2015 |

Like is there any perceivable difference in smoothness? I was curious to the answer to this myself so I just now performed a test. I switched my screen resolution to 1920x1080 @60hz in monitor settings. I played Talos Principle for 5 minutes mostly running from place to place and looking around quickly. I exitted the game and set monitor to 1920x1080 @144hz and loaded up the game again. It was an immediate difference even though my framerate ingame was the same (~50-62fps). Here is the difference; take your mouse and move it around in a circle as fast as you can on a dark background, with 'mouse trails' turned off. You'll 'see' what looks like about 10 afterimages of a mouse cursor behind where the cursor actually is while you're moving it around quickly in a circle. This is at 60hz setting. Changing it to 144hz makes me see about 20-30 afterimages of the mouse cursor as I move it around quickly on a dark background. How this translates ingame is, when I'm turning/looking around quickly enough at 60hz things get 'stuttery' not fps lag, but you're seeing a limited number of static images/afterimages. The difference that's immediate at 144hz compared to 60hz even with the same framerate, is that when turning the visuals are a LOT more smooth. I can much much more easily tell where my mouse cursor actually is on the screen when I'm moving it around quickly as well, ingame or out of game, even though I am perceiving these extra afterimages. Did my best as a layperson to describe the difference, I am sure there are better technical terms and explanations for the improved smoother visuals. I'm extremely happy with the upgrade. mr. nobody fucked around with this message at 17:29 on Apr 12, 2015 |

Thanks for the tip, that stand looks way better. I would get the AOC but I have to import it from the US and the ones available on Amazon don't have global shipping. The LG still has global shipping and it's $150 cheaper than when I originally bought it, but back then it was hosed up and returning it was a huge pain, not willing to go through it again. I wish Dell would make one at the same price point, I've had my current Dell for like 5 years and it's great, and dealing with importing it through them was a breeze.

One monitor is limited to a height of 15.825" (40.2cm) and the other has to fit in a space that's 20.5" wide and 19.25" high (or under 15.825" instead) The desk was originally designed for a single CRT monitor, and I want to fit both monitors under the cabinetry because I need as much space in front as I can get for working. It looks like, yes, I could fit U2412M in here (or even two) if I can drop the monitor down to the bezel. Of course then there's the issue of 'I really don't want to drop $266'.

Where do the intermediate images come from, if the game is only producing a new frame every 16ms? In the mouse pointer case, Windows is generating images more frequently, so you see the intermediate steps. But if instead of A,C,E in terms of images with smaller increments of turning, you have A,B,C,D,E, something has to generate B and D, which means it's generating more frames in a second.

Generally speaking, your GPU generates an image, places it into a buffer, and the buffer is pushed to the display at specific intervals. If the buffer is updated without having pushed the old frame, that frame is effectively dropped. Worst case scenario is the buffer is pushed mid-update which results in screen tearing, which is why you use V-sync to lock your framerate to your refresh rate. The framerate of your game and the refresh rate of your monitor are two entirely separate things, and it's assumed that both sides are able to keep pace with each other. If not, it's likely bottlenecking the other (from an ideal perfect image perspective).

Yes, but he's saying that given the same 60Hz frame rate, he sees differences with a higher monitor refresh rate. If the game isn't calling Present() or whatever more frequently than 60Hz, how is the monitor able to display intermediate frames? Are you saying that the game is really producing, f.e., frames at 90Hz and some of them are just getting obsoleted before scan out? That doesn't sound like what the OP was describing, since he was replying to someone asking about the benefits of 144Hz where the game could only keep up with 60. And he says that in the 144Hz mode he's still seeing the same ~60Hz frame rate, which I would expect to become 90 once the refresh rate is no longer the bottleneck.

Assuming a fixed 60 frames per second, you could have up to a 16ms delay before you see the new frame with a 60hz monitor, while it's closer to 6ms on the 144hz monitor. That helps account for the 'smoothness'. There shouldn't be any intermediate image difference between those though; his example of moving the mouse cursor on the desktop would have FPS in the hundreds if not thousands because it's relatively simple computation for even integrated GPUs these days and I doubt they lock the framerate for that.

He explicitly said that he wasn't talking about lag, which would be that sort of latency. I can see it feeling more responsive, but I don't see how he could get the visual smoothness he was talking about. (I think the modern Windows desktop does composite and scan out at monitor refresh rate, including the mouse pointer.)

The game I tested, unscientifically, on was a game I get a variable but generally high framerate on. That could explain why the higher refresh rate smoothed out the 'apparent framerate'(?) while turning, my fps typically drops while turning in any game on this older machine. Less dropped frames (or more correctly updated frames?) when refresh/generate rates are out of synch, with a higher refresh rate on the monitor?

I can see it feeling more responsive, but I don't see how he could get the visual smoothness he was talking about. I don't know the why of it, but he's most definitely right. I just got the same monitor and the difference in smoothness when playing a game at the same fps in 60hz vs 144hz is night and day especially in first person games. The only way I would be able to describe it is unscientifically: its like when you turn in game, the screen looks like its drawn too slow in 60hz and is choppy. This results in it being extremely hard to tell whats going on around you while turning. I never even noticed this until I played a game in 144hz. In 144hz, its more similar to what happens when you turn your head in real life where the transition from one head position to another is smooth enough that you can see and take in whats happening between the two if that makes sense. Its hard to describe but the result is things look much better in general and in FPS games, I can now accurately shoot guys while turning just as easily as if i was standing still. Its made Wolfenstien a lot more fun to play, actually. Phil Tenderpuss fucked around with this message at 21:35 on Apr 12, 2015 |

I'm interested in the Dell P2715Q. I suppose Windows' high DPI mode is still a loving joke? Talking Windows 8.1 and beyond. Does the monitor interpolate or expect a fix resolution? Say for running games at 1080p instead of 4K.

1080p is exactly half 4k, so you don't get any issues with it. Just 1 pixel becomes 4 pixels.
