Lag results - Samsung A750 vs B650 - Also my Opinion on them both compared - Page 3

Yah... but we want our cake and eat it too!

I don't know of a thread that has a total and complete comprehensive list of all Displays and their input lag. That would be too good to be true. You're just gunna have to do alot of searches and dig through old threads with those models, unfortunately.

Suxs I know. The great sacrifice in 'Big screen gaming'... LAG. At least you'll be losing in style!

That's where the B650 shines, It looks as though Samsung really got the PQ down for Game and PC mode so there's no real sacrifice in PQ when putting it in those modes. It's just that... I'm spoiled. I was really hoping the PC mode was the same amount of input lag but just prettier. Well it's prettier alright, but now the same lag as game mode. If game mode's input lag is sufficient enough for you, then it's all good. For me I still don't know if it's sufficiently low enough for me. I'm going to do some serious gaming between the a750 PC mode and b650 game mode and make my decision by the end of this weekend.

Unless... someone knows of a better panel of roughly the same size and price point?

If someone wants to lend me a crt capable of 1920x1080, I'll gladly give you what the total lag is for all modes on both the a750 and b650. Right now I can only give u numbers against the panels in my house which is those two plus a panny lz800 and a couple LG 25.5" screens.

Did some game playing last night on both panels in standard mode (with AMP on), Game mode, PC mode.

Sigh... I don't know if I need to bother waiting until this weekend.

Impressions:

1) AMP is significantly better than last years' model. On the A750, AMP on any level, I can see graphical anomalies, even with my cross hairs on Call of Duty 4. B650's improved AMP is nearly anomaly free! This is also evident in movies as well. AMP is MUCH IMPROVED on the b650!
2) Gaming on Standard (with AMP) on B650 is virtually unplayable. Sure AMP is improved but wow, at a very noticeable cost to input lag. I'm not kidding, the lag is insane and far worse than the A750's AMP lag! Basically you aren't using the B650 for gaming without putting it in to game mode. The a750 with AMP is borderline playable but then you have all those annoying anomalies of the older AMP so what's the point.
3) Game mode on B650 10x prettier than the A750's game mode, bleah!
4) Game mode on either displays is playable but I *CAN* feel the lag with my mouse controlled aiming reticle in COD4. MHO, you're fooling yourself if you think you aren't at a disadvantage against regular non-hdtv PC gamers online. If the Panny lz800 is roughly 15-30ms lag, the Samsung in Game mode is 50-60ms and the a750's PC mode/VGA is somewhere in-between. I don't even want to guess what the B650 /w AMP is. Again, my *opinion* as far as acceptable input lag, the a750's PC mode/vga is a minimum.

Sigh... I'm just spoiled, I know. I'm at the point to where I feel like just returning them both and waiting for Panny's IPS G1 panel coming out this may and see if it really is possible to have the low input lag of the lz800 but with some motion smoothing 120hz goodness. Just wish they'd make it bigger than 37"!

yah it was mostly TBE. The crosshairs would go nuts when I moved my screen quickly from left to right in any AMP mode on the a750 (latest firmware btw). But I occasionally see other stuff too but at this point, I'm in evaluation mode so i'm actively looking for issues. The b650 exhibits none of the stuff i saw with the a750 even with it's sliders maxed. But it doesn't matter, the added input lag is worse than the TBE errors. It's unusable.

One of my favorite blue-ray movie test scenes is the Matrix Revolutions, the Freeway scene. It's a great scene to test, because the back ground is constantly moving over relatively stationary objects (the actors). Lots of AMP errors during that whole sequence. The b650 handles that entire screen with far less graphical glitches than the a750.

Well guys, I returned the b650.



.... And picked up the b550.



. Lol I couldn't help it. It's a sickness. The curiosity got the best of me and I'm just wonder how the lag will be on samsung's new 60hz set. It's so affordable too, 400 cheaper than both the 40" a750 and b650.


I'll let you know of my results!

Yah this time my GF put it on her card for me. She's a trooper.

At least ya'll can benefit from my obession! I'm hoping to be pleasantly surprised. The PQ looked pretty good at the store. Maybe this will be my keeper... I always say that though.

Samsung B550 HDMI1 named "DVI-PC" vs Samsung A750 HDMI2 named "PC" - B550 is Primary (B550 on left, A750 on right):










As crazy as this is, it looks as Samsung's 09's 60hz LCD panels lags as bad as their new 120hz b650.

I'll do more test later like VGA and Standard and game mode. But I don't think game mode does much on the b550, the screen doesn't even blink out as if it made any signifcant changes like it does on the a750 or b650.

Oh yah - and initial, first look PQ comparison.

-Right off the bat, like the b650, the B550 has a much brighter screen than the a750. Blacks appear a bit deeper too.

-Less clouding/flash lighting than the a750, virtually none. Better QC or luck?

-Doh! a dead pixel (not stuck but dead). So much for QC or luck. a750 and b650 had no stuck/dead pixels btw.

-Colors are vastly different between the a750 and b550. In fact when viewing this very forum, the pastel background colors are very different than the a750. Skin tones are very different. I don't have a reference so I don't know which display is more correct but I prefer the b550s as I don't think ppl should be as tan as they seem on my a750. b550 has a slight green push where the a750 has a slight red push. They both probably need some calibration regardless.

-Pixels seem... bigger on the B550 for a lack of a better description. I dunno how quite to explain it, it's definitely not as good of a monitor to sit 3 feet away from compared to the A750. The picture looks "cleaner" and pixels are less noticeable on the a750. The B550 has sort of a noisier picture in general. I think Samsung changed panel types in 09. I need to take a macro picture of both displays to see how their pixels look close up.

-Color transitions not quite as smooth. 10bit vs 8 bit? I dunno.

-Despite all that, it's still an overall good looking monitor though!

That's it for now... g'Nite folks.

I looked. It seems as though Samsung stopped shooting themselves in the foot by marking their panels with these 09 panels. There's no longer a letter following the model on the back.

The A750 is an S panel, according to the label on the back btw. But who knows, I read late in 08 Samsung got wind of all the negative press about panel types and start labeling them all S.
