Hazro - Any Update?

As I'm an LCD newbie I have to ask. Why would you disable vsync when using an LCD ?

When running at more then 60fps you only see 60fps ?
When running at less than 60pfs you see less than 60fps ?

As philjohn says, you see some small input lag (which is more noticable when you have a TFT with some built-in lag already, and maybe more lag from ping in online games).


But more importantly, not all games properly support triple-buffer vsync. This means that with vsync enabled you will get sudden jumps in framerate. For example, if your card could output 61fps, you would see 60, which is great. But as soon as the maximum framerate the card could output drops below 60, the displayed framerate drops to 30.

30fps isn't ideal, but the real killer is the constant switching between the different regimes. It really ruins the illusion of motion. Only integer-divisions of the maximum framerate are available, ie: 60fps, 30fps, 20, 15, 12, 10 etc...
 
Nice explanations, thank you guys.

So with vsync on and buffering working, for a given frame rate less than 60fps the actual frame rate you see is equal to the nearest integer division less than said frame rate. As the frame rate changes the actual rate you see jumps between these integer devisions.

With vsync off, the difference between 60fps and the actual card frame rate determines how close to the bottom of the screen any potential tearing will occur. As the frame rate changes the position of this potential tear line will move up and down.

With triple buffer vsync working, the only real drawback is the slight input lag (and a slight overhead in the GPU memory to hold the extra frame), other than that the frame output is as you would expect, up to a maximum of 60fps. But not everything supports triple buffering properly, and 'regular' double-buffer vsync works as you describe (except that it always rounds down to the next integer division, rather than taking the closest).

But yes - with vsync off you see the tear-line, which fluctuates around over the screen. Depending on the scree, the framerate, and the users eye, this can either be acceptible or extremely irritating :p
 
I don't know of any dates for the 26" I'm afraid!

I have an update for people too. The backlight uniformity issue is there on mine BUT the difference was not noticeable to begin with on mine until I decided to check using the colorimeter tonight during recalibration.

The left side is 183cd/m2 middle is 172 and right side is 145 so on mine the right side is a bit darker than the middle and left which are more or less the same.

I've since recalibrated with brightness at default (48) and contrast at 12.

So better results than before with a nicer overall luminance.
 
Got my 26" this week. It's beautiful. i was using Spyder Elite Pro to calibrate it(after messing with the OSD for a bit). Spyder recommended I start with the Factory settings on the monitor. So I did. BAM! No monitor. Black sceen, no signal then it shuts off. Oi! It no longer gets a signal from the computer. WTF! Hazro - no response. Me - irked!
Anyone know what I should be trying for a cure to this problem?

BTW, I ordered it about 6 weeks ago and it just came on the 7th for those of you who are still waiting. Hope that helps a bit. maybe they are all on the way!!
 
Well your post seems to assume there's something wrong with the hazro, my post mentioned trying it on a different PC....to confirm....seriously...
 
Is there a way to force the refresh rate on your GFX card to say 60Hz or 59Hz? it sounds to me like the refresh rate is out of sync. This would certainly be the case if you can see a picture on the PC at bootup before windows loads.

i hope i didnt put you off by my tone. I was simply stating that I would be "completely aghast" if "something were wrong" with the Hazro. Nothing more, just wanted to clarify. cheers

Im not really seeing a "picture" at all. Just the little bouncing box saying no signal. I will check my card and try to force a refresh.
 
i have a question. My second monitor is a Samsung 2233bw, it's nice. But unlike the Hazro it came with a driver installation CD. The Hazro - just cables. I don't know the first thing about monitors, but it made me querious. Does Hazro make drivers for their products?

I think someone mentioned in this thread about a hard reset mode on the Hazro but this may be 24" only, if you hold the up or down arrow during power on it should reset to defaults. Might be worth trying.

Driers aren’t needed for monitors as they are Pllug&Play standard these days. The discs you get with some models are just software suites that can control colour etc and also some contain an icm profile to assign to the screen.

I don’t see the point in assigning the ICM profile as every single monitor is different, even the same model. Each one needs calibrating because the same settings won’t give the same results on the next monitor on the production line.

Just tried the reset. Didn't work. Must be for the 24" only. All I get from the monitor is it saying Analog: resolution searching just before it shuts down...

AHHHH! I SEE IT NOW!

basically what you need to do before it shuts down is press the "input select button" then scroll to the DVI input and BAM! DVI signal :p

It's not particularly clear on WTF is going on when you startup on a non active input :p
