Acer 120Hz 23.6" 1920x1080 LCD... but it's orange!

So is this the upgrade I've been waiting for? While I love my 26" Asus anything that gets me closer to CRT non ghosting is an upgrade IMHO. Losing the 2 inches wouldn't be a show stopper. I've found some games actually become more difficult to play due to the large screen, WoW and RTS'es for example. It takes my mind longer to locate and click on an icon or action button I need. A 24" may actually be perfect.

So as far as ghosting is the Acer an upgrade?
 
Yea most people mention FPS games as getting the biggest advantage but racing games especially feels much more smoother, fun and realistic to play as well. A perfect example besides Richard Burns Rally is FlatOut 1 & 2, just try it out and see for yourself, I'd say it makes more of a difference than Richard Burns Rally imo even. I thought even 85Hz vs 100Hz on my CRT was unacceptable when 100Hz felt so much smoother with it.

Seems, according to Tom, Alienware overall better :/

I don't know, all I read from that was the Acer has better 'dark contrast', buttons with tactile-feedback, and is $100 cheaper.

I'm probably waiting for the two others to come out since I've made it this far without pulling the trigger. I still don't like that bezel, that's probably it. I need me a fast TN for my games but I love my 20" IPS.

a much more patient man than I, as I just had to get my Hands on one. Would love some real stats and better comparison charts between the two.
 
Theres something fishy about that site. No actual test methods or results, just 1-to-10 scale scores. How they can score response time without testing response time is beyond me.

You're telling me Rix, I'd love some stats with real numbers. I don't want to be a fanboy by any stretch of the imagination (definately love this monitor) but objective comparisons seem all too hard for some :/

Anyone done an input lag test vs CRT?

The main issue for this is we don't have CRT's which will do 1920x1080@120hz. (Think clone mode.. need same res+refresh rate).

I have tried something out using 2 PC's and basically running a timer on each computer. With my CRT @120hz on one computer and the AW2310@120hz on the other computer. This still allows us to compare the increments in the data to see which one is 'behind' more, from each picture to each picture.

But my main issue was that the camera might not take pictures at constant intervals. I'll post my data from the ~150 shots I had taken to see if someone had a good idea on how to go through it to get some pertinent information.

The other issue would be that the timer might have run faster on one PC compared to the other PC. And we have no way of correcting for it.


Edit: Just remembered about a thing called.. RDP lol... here's the "data". This is only the "time" from the timer on each screen. They don't match because it was being run on separate computers.

Druneau, Thanks for the post. I don't think that data will do us any good until a couple more parameters are controlled.

First, even an FW900 can't do 1920x1080 at 120Hz?
1920x1080x120x3 = 750 MHz. Is that doable? (did I calcualte that right...)

If no, I have a few ideas:

1.) How about a high end CRT projector... http://www.curtpalme.com/Projector_Rankings.shtm


2.) We could test at a non-native res. Many LCD do upscaling without any lag.
Get two of these ACERS side by side. Measure relative lag with one in native and one in downscaled res to get a reference for lag induced due to scaling.

Then test the ACER at the downscaled res against a CRT.

3.) Building on your idea, Druneau:

Need a local network of at least 3 PC's, using good NIC's and router for <1 ms lag
1.) "master"
2.) machine with acer hooked up
3.) machine with CRT hooked up

steps:

1.) RDP from master to both 2.) and 3.) system.
2.) Start timer program on both system at same time (must find way to assign shortcut key or macro or somthing to initiate both timers simultaniously.)
3.) photograph both screens as usual at ~1/240 sec shutter or better.


4.) Better yet, just use two machine and rig a STDP switch to mouse buttons on both machine and use the switch to click" start" on the timer. Be sure to do this several times and switch the systems the monitors are attached to.
 
I'll read through this tonight. I have to check for projector, we have a CRT projector at home lol (Mitsubishi VS something "The big one" 175lbs...)

As for my "data", we can easily substract the first reading in each column to "zero" the numbers.. but then we are still subject to lag from the pc's.

I guess I could do the same without "clone" mode. Just go 1280x1024@120hz on my CRT and 1920x1080@120hz on my crt... timer on each.

Only problem right now is I don't have my CRT at the moment. So lcd only.

Our crt projector is the VS-1281. Specs from website:

VS-1281 7" - Digital 900 15-103 40-150 80 70-300 1600x1200p Y V/S/R N Y Y 20990
 
You may want to start a new thread specifically for determining input lag on monitors with resolutions higher than is commonly available on CRTs. This is a significant question which should have its own thread for future reference.
 
Hi there.

This is my first post in here after reading the whole thread.
I have my brand new GD245 for 3 days now, and i'm quite impressed with its performance, but i'm having an issue that's driving me crazy.
I have an i7 with an ATI 5850, and come from a 28" HannsG, and mainly i use the PC for FPS gaming.
On games, the monitor runs smooth and fast, no ghosting at all (tried MW2, BFBC2 beta, and Bioshock2), barely no bleeding... everything OK.
My problem comes in windows (W7) desktop. Fonts and characters appear like defocused, they have like a shadow between characters, and this is killing my eyes.
I saw a similar issue on another LCD time ago and the problem was with the HDMI cable, so i tried with the Dual link DVI, single link, HDMI, connected the laptop to the monitor, and all with the same results (on every frecuency range between 60-120Hz). I have re-installed drivers, and tried another SO, even downloaded the LCD driver from Acer web... no love. And if i connect my old LCD, everything shows Ok.
I'm not sure now, but maybe the 1st day i tried the monitor didnt had the issue, but after all this hell of tests, i cant assure it. Has anyone installed the monitor driver? It isnt digitally signed, and i dont know if that was the begining of all this shit.

Oh, i have also tried all that ClearType stuff that comes with W7 with no results.

I have done some photos, but they can't show the issue clearly. Anyway i'll upload them later, i'm at work now.

I don't know what else to do before sending the Monitor back for change, and that's the last option, since there isn't stock of it. And a little voice in my head tells me that this is something stupid and not a monitor issue...

Thanks.

I believe there was a bug with 2D/120hz + ATi but it was resolved in the cat 10.2's. If you haven't upgraded, that may be the place I'd start.

I already did. Even completely uninsalled and reinstalld the drivers, and tried 60Hz also, and no results :(
 
Try running a game in windowed mode so you can see the desktop behind. This could confirm if it's "fixed" when in 3D clocks.
 
hi Guys,

Have the monitor for 3 days thus far, freakin' amazing.

How does one go about best calibrating the colour and contrast/brightness. Can someone put up a guide or point me to a program/list where I can do this myself?

I'm fucking sick with this shit.

Disable Cleartype (or whatever it is called on Windows 7) or tune it to suit your monitor.

*edit* Here.

*edit2* seems like you have tried it already? Even if you disable cleartype and it still looks defocused, I have no idea what could cause this.

I have the same issue, I posted about it a few pages back. If I adjust my view angle to the screen (either sitting up straight or moving forward and up) I can mostly eliminate the issue.
 
Well, there is an angle, looking the monitor like 20 degrees up that the issue dissapears. Now i just want to know if this is just a few wrong panels, or generalised, in order to return the monitor o change it for another unit. :confused:
 
I cant see what the problem is from those photos. Besides the laptop screen looking really pixelated.

If you take a screenshot of the problem and look at it on a different monitor, does it render incorrectly still or is it just when displayed on the monitor? In other words, is this a text display issue with win7 or not.
 
That's the same thing I noticed on Samsung 2233rz and depending on what ClearType text settings I used it was more or less visible. On this VX2268wm I can't see it whatever ClearType text settings I use.

It looks like edge enhancement/sharpening.
Click to expand...

This monitor has it in spades, and so far, even though I've found the service menu, it is completely non-adjustable. This shows up especially with the color fringing with cleartype fonts, and a white fringe (without cleartype) that shows up on fonts that are black on grey, such as menu text. Otherwise it's not a bad screen and the 120hz does work as advertised with my 5870.

That's one of only two dislikes I have with the screen: The over aggressive sharpening, and the lack of a direct input change button. Most other monitors in this class have a single, direct button that you can press to switch through the inputs. This one you have to enter the menu, and then hit the right most button to switch.

There is no ghosting, but there is still motion blur, albeit very low, and probably close to class-leading from what I see. Funny enough vertical movement/scrolling seems better resolved than horizontal movement. I might try and do some input lag testing with a VGA splitter and calibrate it with my Eye One Display 2 hardware and software and report back. Colors seem fine IMHO. Input lag also seems minimal, if there is any at all.

BTW, the panel is a CMO 120hz 23.5" panel. Going from memory it said CMO-M236-L02.

You can find this out by entering the service menu as such:

1) Turn off the screen

2) Hold down any of the control buttons at the bottom and turn on the monitor, while still holding the bottom "action" button. I used the one closest to the Power button.

3) Wait for the Acer logo to appear and then disappear and then let go of the button

4) Hit the middle button on the bottom (third from the right) and you should see a screen with Overdrive settings, and some other color settings

Wow, image sharpening - and you can't turn it off? this is a digital display, right? :rolleyes: - unacceptable.

Thanks for the work on getting the service menu.
 
Is that with ACM mode on or off, or both? Speaking of which, anyone have non-marketing info on the ACM mode? Is it good for anything?
a press release said:
Users can clearly view detailed images and crisp graphics due to the Acer GD235HZ display's 80,000:1 (ACM) contrast ratio. The Acer Adaptive Contrast Management (ACM) features advanced technology that allows users to adjust images frame by frame to optimize contrast by enhancing detail and gradation. Additionally, Acer ACM enables the new monitor to use less power and save energy while providing a superior viewing experience.

Good thought. Disable that ACM thing and see if the sharpening goes away. May also serve to reduce input lag.

Its not that bad. You double-tap the right most button and it cycles inputs.

Thanks for the service menu stuff. From there the controls are the same as for the normal OSD.

I have the same panel listed:
CMO M236-L02
ACM Off
EDID WP On
Panel Span 76 Step 483
DDR Span 833 Step 11
OD On
HPD On
Lifetime 214 H 52 M (nice thing to track!!)
GD245HQ MH M002 1215
GD235HZ MH M002 1215

So the euro version 245HQ is literally the same panel as the 235HZ, confirming what we already knew but its nice to see it.

So with the ACM off, does it improve the problem?
What happens to input lag/colour accuracy?

- lovin this monitor. Batman in 3D is very impressive, and the silky smoothness of Team Fortress 2 in 120hz..could never go back to my 60hz screen..never.
 
I finally sent the monitor to Acer. If the way it worked is normal, it's unnaceptable for me. Now 1 month without it...
 
After 16 days, the repair case is Closed. Just called Acer and they told me "Panel adjust and review with no problems detected". So 20 days without monitor and, as expected, they didnt find a shit. Let's see how it comes back. I'll keep you updated.
 
I've had this monitor for maybe 4 days now and I did notice crazy blurry/smudged text.

Well, I think it must have been the drivers cuz I just updated my 5850 to the leaked Catalyst 10.3 and it's crystal clear (was using 10.2 before). Actually, come to think of it, I had it through HDMI before and now it's through the double-link DVI so it might have been that. I'll experiment and report back.

There is one thing that is still bugging me though. Since I now have my cable box hooked up to the HDMI input, whenever Windows (7) shuts down the display (kills the signal) the input automatically switches to the next active one which is HDMI. Even if my cable box is off, it must have some signal as it switches to and stays at HDMI.
When I turn my PC back on, I have to manually switch it back to DVI.
