Hello there, I'm really interested in getting this monitor but I'd like to know if anyone knows for sure if I could play at 800x600 & 1024x768 @ 120/144 with g-sync enabled ? I don't see them listed in the standard timing table

but could it be possible anyways ?

thanks in advance

Hi 1024x768 is a resolution option in Nvidia Control Panel. Why would you want to play at those resolutions? 1024x768 is a tiny square I have just tried it

It's for older games like CS, I'm so used to it that I don't wanna change it. So you're sure it'll work at 144 ?

I have just tried those resolutions 800x600 & 1024x768 on Hitman Absolution and G sync does not work!

Ow, and it worked with the other resolutions ? is 144hz available in windows for 800x600 and 1024x768 or only 60hz ?

thanks for helping me decide btw!

Bought the XB270HA and have been using for a few days now. The uneven backlight is a bummer; it's noticeably brighter on the bottom 1/3rd or so, then darkens for the top 2/3rds. It's not something you notice all the time, but is especially noticeable in dark scenes. I wouldn't quite call it bleed, as it's just barely at a tolerable level. Also as a result, it exhibits an ever so slight color shift...it basically looks like when you look at most TN panels at a slight angle: an all-white field looks brighter on the bottom 1/3rd and slightly darker/more yellowish as it goes up the rest of the 2/3rds while a light gray field skews to lighter gray/verging on pink territory... only, this is when you're looking at the entire panel head-on (i.e., there is no angle that allows no backlight or color shift...it's there no matter what). You can even see basically the same thing in the previously linked youtube video where you can tell the lower 1/3 (and within there, even more pronounced a bit on the right-hand side of that lower 1/3rd) the backlight is a bit brighter and almost bleeding. This leads me to believe that most if not all panels will basically have the same artifact (perhaps a function of how the innards where designed with the G-sync panel itself in relation to the LED backlight panel...just a guess). Having seen other displays with inky blacks, this is quite a step back into the Gray where I feel like I need to tie broken mini booze bottles to my knuckles and fight Liam Neeson and some wolves to the death just to see if there's a God. The contrast is still relatively good, though (although not as good on that lower 1/3rd...for your 3rd person action games, your character when in the shadows is simply going to be gray).

Having said all of that, both G-Sync and ULMB work awesomely well, especially G-Sync! Indeed ULMB can only really be used in a darkened room, but then it has plenty of lumens at that point. G-Sync at 144Hz is definitely the winner between the two, with the only odd "bug" I've found so far being in Mass Effect 3 when you pause the action to cue commands, for some reason within that mode it is not smooth (this bug doesn't happen when using ULMB or no G-Sync/ULMB at all). The colors and crispness (no sharpness control, but it's definitely neutral...neither sharpening nor anti-sharp/blur applied) are very good. Other than what I described above, no major color shifting when moving your head around and looking at different angles. Grayscale and color temp (when on Warm) seem pretty accurate and close to 6500K out of the box (just need to adjust brightness & contrast in Nvidia control panel for desktop, then do each game individually either in-game or with something like SoftMCCS (which I've yet to play with)).

So, I think the bottom line is we're still waiting for that holy grail of G-Sync plus a better panel with deep blacks. I would gladly trade a nice IPS panel for some inherent lag. Better yet, give me an OLED panel with G-Sync! I also ordered the Philips 272G5DYEB for the hell of it to compare, but from the specs I'm expecting the exact same panel as the Acer, with perhaps just a slightly different GUI. Perhaps I'll get lucky and the Philips' backlight will be more uniform, in which case the Acer is going back. Regardless, I'll post a comparison of the two somewhere here at some point.

EDIT: Forgot to mention, in my shopping spree, I also bought the 3D Vision 2s...works great with the Acer...minimal (though still very slightly there) ghosting and certainly a quite convincing effect. This of course does not work in conjunction with G-Sync...it's either/or.

For anyone who cares: got the Philips in today and it's the exact same panel quality as I described before with the Acer. ULMB lumens performance is the same, also. The only differences are:

-Power brick instead of straight power cord
-Touch panel for monitor controls vs push buttons on the Acer
-OSD is nicer/fancier with the ability to go transparent and move around the screen
-No separate preset profiles that I can see (Acer has User plus preset profiles: Eco, Standard, Graphics, Theater).
-ULMB Pulse Width setting (10-100, 100 default). I'll need to double-check, but this setting is not on the Acer.

I'm not sure how important the ULMB pulse width setting is or if I would ever use/need it. My gut reaction is to return the Philips and keep the Acer, simply because in my particular setup, the extra power brick is a pain in my power brick.

For me, if I were to buy a monitor right now, no pulse width settings = no buy. Customizing the strobe length is a must for me (I use a very low setting).

I'll give it a shot tonight when I can pay it better attention. Lowering the pulse width just seemed to make the picture dimmer (considerably so at lower settings). What, exactly, is the benefit of having this?

From what i have gathered its mainly there to help out people with eye strain due to the brightness of the panel. That way they are able to control it. I to just picked up the XB270HA,thanks for your post regarding the difference between this and the Phillips. Helped justify my purchase that much more. When i looked at the stats on both i had a hunch it was basically the same monitor. With that said i do agree as well that the back light in these tn monitors have brighter spots to them...That's kinda a bummer the light omitted couldn't be uniform throughout. Nonetheless i don't really notice it when i gaming which is nice but if you say put up a solid color (black wallpaper) it seems to look a bit more washed out in the bottom right hand and bottom of the screen opposed to the upper half where it the black looks deeper and dark.
