Better LightBoost Color for VG248QE?

Someone I trust (the moderator of HardwareCanucks, a Canadian computer discussion forum), says that the VG248QE now has better LightBoost colors with the latest nVidia drivers.

lowfat, that is good news for the VG248QE monitors! Which driver version?

I'm still trying to confirm which nVidia driver version, but has anyone else noticed better LightBoost colors with newer 320.49 drivers? I did report directly to nVidia's Driver Team forums with a copy of NCX's (MenancingTuba) flawed colorimeter results, and I think that caught nVidia's attention.

Any confirmations?

Not always, but HDMI 1.3a has the bandwidth to allow it, just not an officially documented/supported mode.

Not guaranteed to work. But it has worked sometimes before even with HDMI 1.3 chips.

Hence the 'out of the box'. tongue.gif It was never about bandwidth limitations but rather what the ports were (apparently artificially) limited to doing or not doing according to certain standards. I hate HDMI for this and other reasons. guiltysmiley.gif

Thanks for the tip! I've managed to get up to 85hz on my VG247QE with Evga pixel clock OC using this HDMI cable http://www.thewarehouse.co.nz/red/catalog/product/Sony-1-Metre-High-Speed-HDMI-Cable-with-Ethernet-DLCHE10C?SKU=1703681

However I cannot reach higher refresh rates like 100 or 120. Do you think that is because the cable version is 1.3? I cannot use 720p somehow it reverts back to 1080p when I try 120hz @ 720p resolution.

i think that it will be the pcb stopping it. i achieved simlar results with another monitor. 85 hz was borderline and 82hz was perfect

Weird thing. I grabbed a 1.4a cable and tried it
Now the monitor gives Out of range error when i try 100hz, but it gives "HDMI no signal" when i try 120hz.
That make me think the cable doesnt support 120hz@1080p, but then again it supports 100hz and it's certain that monitor also supports that as well

Edit: even weirder, when i use a 1.3 cable, it gives "out of range" error at each refresh rate (100/120). No "HDMI no signal" errors.

I am using the VG248QE and enabling lightboost with all the required settings gives me these weird vertical green and sometimes purple lines in whatever game or application i'm running. The lines are not moving at all, I have tried different ICC profiles and adjusting colors in the NVIDIA control panel, but nothing can get these lines to go away. Any thoughts?

Do you have a photo? Can you take one and post it?

You may wish to get the monitor exchanged. I suspect this is a defect. Try a different DVI-D cable too, just in case it's the culprit.

Are they alternating light and dark lines down the screen? I have that sometimes with lightboost enabled, although it's pretty subtle.

Here is what i'm seeing throughout the entire screen.

Yes, I have been able to overclock HDMI and single-link DVI (essentially the same) to gain enough bandwidth to allow 120 Hz 1080P. It's how I got 120 Hz 5x1 portrait working. Your mileage may vary on the card and cable being used.
