Samsung S23A750D 3D LCD Display

Measuring lag on the Samsung was much easier than most panels. Typically when taking shots of an LCD next to a CRT monitor, the FPS numbers on the LCD will be blurry in a shot at least half the time. This is since we’re running at 60Hz and only shooting at 3-4 times that rate, so often we are between frames. With the 120Hz rate of the Samsung, almost all of my images were sharp and clear, which made this bench test much easier than usual.
Our overall lag would typically be less than 1 frame, since we usually deal with a 60Hz LCD, but in this case it was just over 1 frame since it is a 120Hz display. This is still a little better than most displays, and the faster refresh means that even if you have a frame of lag, that next frame is coming twice as fast as it would with a typical 60Hz display, so the effect should feel like less. I also tried to increase the response time of the display through the menu but had no change in the lag results.
The power use of the Samsung was a bit higher than a normal LCD, though this could easily be due to the 120Hz refresh rate that uses more power. Samsung doesn’t make a 60Hz version so there’s no way to check for certain that it’s the cause of the use. The power use was still very reasonable for the display size.

"Not everything has to be written like a technical brief presentation or be a class on the electronics of how TN panels work."Maybe not, but on Anandtech, I'm come to expect that level of precision technical writing and explanation.

Erm, makes me wonder if some of the nitpickers would complain about getting too much money in their EBT checks. Before complaining, one may want to remember that this info is, erm, Free! The writing is fine. Some of them may not use English as their first language. Some of the readers may not either. I, at least, like the chatty style more than the antiseptic, scientific style that more anal retentive types seem to like. I even like comments about power supplies. Naturally, I can understand that some would prefer to change all that to make the rest of us more like themselves. Erm, that is all I have to say...ImSpartacus - Saturday, December 17, 2011 - link
I have a problem with posters that use caps lock in a potentially rude manner.The tone of your post is already flirting with "rude". Using upper case characters nudges it over the edge. I cannot tolerate rude comments from individuals that represent Anandtech.
I suggest not replying using language that could be interpreted as rude.
To help achieve this goal, I suggest reading some of Anand's comments from past articles. He has an especially fantastic tone to every one of his comments.
I hope Anandtech maintains its exemplary reputation of mature and thoughtful staff.
Cheers!

I used caps because there is no bold (yes, this system is in need of an update). I wasn't trying to be rude, sorry if it sounded like that. I was just trying to get the message out in as short as possible. The poster didn't bother reading the article, so I couldn't be sure that he bothers reading my comment as a whole.Kristian Vättö - Sunday, December 18, 2011 - link
Also, thanks for the feedback. We (well, I in this case) can't really learn without someone else saying what is wrong. If someone bothers to comment about it, it must be something that actually has a value to someone.I'll be sure to pay more attention to my language in the future. Not that I post replies like the above often (first time I think)

"I hope Anandtech maintains its exemplary reputation of mature and thoughtful staff."We most definitely will :)
Take care,
Anand

I honestly did try to give examples. I spent a good 15 minutes trying to copy/paste a few sentences, but I can't change pages in the article without losing the post I'm writing. So then I started using print screen and erased my entire post that was in clipboard, so I said screw it.Here are some from "Lag and Power Usage".
", so the effect should feel like less." Like, for sure!
"The power use of the Samsung was a bit higher than a normal LCD, though this could easily be due to the 120Hz refresh rate that uses more power." should be something along the lines of "Power consumption of the Samsung was a bit higher than a normal LCD, though this could easily be due to the 120Hz refresh rate."
There are tons in the summary page from what little I saw of it.
Hey thanks for calling out a 13-year account as a "hater."

This is what I saw in the introduction."Virtually every game now is rendered in 3D, and so all of the information is there that is needed to show the game in 3D to the user..."
"Virtually every game today is rendered in 3D and thus have all the information needed to be displayed in 3D..."
I did not understand what was being said in the very next sentence. What is "running in active 3D"?

Sorry about the hater part, I would edit it out if we had that option. It just triggered me because it was the second comment and you clearly admitted that you only took a glance and still said it's bad. Okay, I know taking a glance has varying interpretations but from a writer's standpoint, your earlier comment was among the worst ones.The good thing is that you came back and did what you should have done in the first post: Provided some examples. That is how we can learn and also edit or explain ourselves if needed.
For future use, you can open the article in another tab/window so you can keep posting the comment in one tab/window while reading the article in the other ;-)

OK, here's my opinion: I don't really want to know about the writer's _off-topic_ difficulty in setting up an environment or rig to test the equipment, unless it's actually very interesting or amusing or written in an entertaining style (but that sort of thing should belong on a blog or a different section ala Byte's Chaos Manor or an entertainment-oriented publication/show e.g. Top Gear).Unfortunately the entire section on the lack of suitable PSU and display card and the resulting solution was not interesting, amusing nor entertaining. An editor would cut that section (and PSU gallery) entirely out. It just gives me the impression that the writer may be shilling for something/someone. Like those clumsy product placements in movies.
The rest of the review is OK from a glance, assuming the measurements etc were correct and done correctly.
