ASUS VG236H 23-inch 3D Display Review: 120Hz is the Future
by Brian Klug on August 7, 2010 2:48 AM ESTBrightness and Contrast
For brightness we display white and black levels at maximum and minimum brightness as allowed by the OSD, and divide the two to get contrast. We use the same colorimeter described earlier. In this case, an Xrite i1D2 with ColorEyes Display Pro.
The VG236H uses a CCFL backlight, but thankfully warm up times are very quick. There’s still settle, so we wait 30 minutes between adjusting from 100 to 200 nits before calibrating (that’s the last section), but brightness does change and slowly stop like any CCFL and even WLED display.
The VG236H is thankfully a very bright display, exceeding the 400 nit advertised maximum and getting up to 431 nits. Brightness is really important for these 3D displays as using the active shutter glasses perceptibly reduces brightness. Thankfully, the VG236H is bright enough that it doesn’t make games impossibly dark.
Similarly, contrast and black levels are important. Black levels are pretty good, but not stellar at maximum brightness. They’re good enough to net the display a contrast ratio of 925 at maximum brightness, which is pretty impressive.
On the whole I’m pretty pleased with the display characteristics on paper, the VG236H is an admirable TN performer, arguably one of the best.

Is there any monitor that supports HDMI 1.4a (and thus, 3D over HDMI)?With the upcoming HDMI 1.4 GPUs, I just wish we had a monitor capable of acting as a sink for those signals instead of having to hunt down a 3D TV to test it out!

two other 120hz computer monitors i can find online...http://accessories.us.dell.com/sna/products/Displa...
i can't, for the life of me, figure out what revision of the HDMI standard it uses. alienware does not report those details, and dell offers no manual for this monitor in their support page. someone would have to call them and ask, but i live outside the US.
and an acer model...

this product sheet has a maximum reported 75hz over HDMI, so I am going to say "NO," not 1.4a, but it doesn't actually say that.

If 3-D game technology works the same as 3-D Blu-Ray, then it's really only 60Hz x2 (alternating per eye). It may be capable of 120Hz natively, it may display 120Hz from 2-D, but for 3-D I'm pretty sure you're still only getting 60Hz per eye.What strikes me most about this whole 120Hz topic is that I had a Sony CRT that could handle 1280x1024 @ 240Hz about 10 years ago. And yes, VSYNC @ 240Hz is why the LCD boom disappointed me so much. LCDs, while thin and light, were a horrible step backward for gaming - at least for those of us who were used to high framerates and refresh rates.
LCDs still have such catching up to do...

you'll get no argument from me about lcds vs crts.but that's the way the industry has gone, oh well.
in any case, the acer monitor specs the HDMI 70Hz, and a different refresh rate of 120Hz for using DVI.
I believe that HDMI 1.4a is capable of delivering more than 70Hz, so I was attempting to answer that question, not to determine whether or not it is capable of playing 3D over HDMI. However, ganesh seems to think so, and I was giving him the benefit of the doubt there.
As to the second question, is there a someone who can say with authority that 3D can (or cannot) play over HDMI with a limit of a 70Hz refresh rate?

http://www.nvidia.com/object/3d-vision-requirement...this nvidia 3d vision compatibility chart is interesting.
looks like 120Hz refresh is definitely a necessity for 3D.

It clearly states in the article that the 3D effect is 60Hz each eye. Brian's comments lead me to believe it is a true 120Hz display in 2D, but I can't say that's a fact.I have to agree about the refresh rate - and it's one reason why I run a Sony FW900 CRT. I run it @ 85Hz, 1920x1200. 60 Hz is a poor standard to settle for, in my opinion. I know we all live with 60Hz flashes in our modern lives and think nothing of it, we are conditioned to our lighting doing that, but it makes a difference. 100 Hz should be the standard we build to, not 60.
I was excited about this monitor at first, but .265 dot pitch and 1920x1080 aren't what I want. .265 is better than the LCD I have, but not much, and I prefer the 16:10 over 16:9 ratio.

I know this is an old comment, but I can confirm that it is indeed a 120hz 2D display. I haven't used it for 3D stuff yet. I just use it as a 120hz display and enjoy a much smoother interface. ATI config reports its maximum refresh rate as 120.Luke212 - Sunday, August 22, 2010 - link
hate to tell you but the highest ever Sony at that 1024 would have been 126HzCushgod - Wednesday, December 8, 2010 - link
I 240% agree with you!! :P LCD's do have catching up to do ... its sad we are coming back to the Hz I used to enjoy. I am currently on an asus-vg236h, and I am thrilled to play all my games with better framerate, and clear and smotth scrolling left and right turning, awesome BF BC2, Warhammer, and Global Agenda look beautiful. Its night and day to me. Night and Day.Fleeb - Saturday, August 7, 2010 - link
Why HDMI for monitors when DisplayPort can do the job?
