No. It's more likely the replacement has something different about it, but I still find it strange.bb23 said:I see. Regarding the Samsungs, they are 4 years old now so maybe one slowed down more with age?
Yes. I don't consider Digital Versus to be reliable anymore. Some of the results they have published are nonsensical. Lag can't jump around from 0-32 ms. Sometimes the average comes close to the actual lag, but it's not reliable. If they were using a precise testing method, the results would always be consistent.bb23 said:So the 32ms from DigitalVersus.com was probably determined using the standard timer method?
He says the ViewSonic VX922 has 15-20 ms when it really has no significant lag, so his results seem to be one frame off. That can happen when using a timer with clone mode because you can't tell where each monitor is refreshing. The LCD might only be 2-3 ms behind due to response times, and clone mode desynchronization can push the refresh back even further, making it look like it's a frame behind when it's not.bb23 said:
Yes, but it's more likely the screens won't be synchronized when testing DVI vs. VGA. Even if there is tearing, if you wait for the tearing to roll off the screen, the results will be accurate enough. Using a splitter isn't really necessary in that case. You don't need a VGA port. Most video cards can output a VGA signal through the DVI port with a simple adapter.bb23 said:ToastyX, given this method you are referring to, is the CRT all that I will need?
No. I haven't seen VGA make a difference. That article applies to HDTVs, which tend to do image processing on the HDMI ports. Most monitors don't have a way to reduce lag. The Dell U2410 is a notable exception, where game mode supposedly reduces the lag by one frame, but that monitor has advanced color features, which game mode supposedly disables. None of Dell's other monitors are like that, and game mode is usually just an ugly color preset on most monitors.bb23 said:Another test I was thinking of, is to use a DVI to VGA adapter and test the HP's VGA port vs. the Samsung. Do you think using VGA might eliminate some lag, as suggested in the article I linked to earlier today?
Many thanks for that very informative post, ToastyX!
If there are any gamers that have this monitor and can at least give us their subjective impressions, especially relative to input lag, that would be great - and even better if you have a CRT and can do this input lag test, which is very straightforward to do. Thanks.
Mine should be here tomorrow. All I do is play FPS games. I'll give a report after some gaming.
Ah damnit I saw there location of the place was in Penn so I was hoping to get it wed or thursday (I'm in NY). But of course the warehouse it ships from is in god damn Oregon, now it's not supposed to be here until Monday...
That's great to hear! Thanks for your great input.Those shots show the HP has no significant lag, maybe 3 ms max + pixel response time. The bars are drawn from left to right, so the newest right-most bar is what you want to look at. The total transition time is less than a frame. The results seem consistent too, with no tearing. Interestingly, picture #20 shows the program skipped a frame for some reason, but that doesn't change the results.
For the above test you don't need a splitter. Just put the HP and the CRT in clone mode, run the test, and shoot the two screens with your camera. (At least my video card did not require a splitter. Dunno overall though.) More tests would be good.I do have a CRT monitor, but I don't have any sort of splitter to do input lag tests either.
To answer my own question, HP pointed me at the appropriate web page, which is:An HP 30 day return policy has been mentioned here many times, almost always as something said over the phone by an HP rep.
Is there any on-line confirmation of this on a web page, or is there anything in invoices or order confirmation e-mails about it?
I've not been able to find anything on-line that confirms it, and would appreciate hearing that there is a hard confirmation somewhere.
