tx panel is the same except it can do 3d over hdmi 1.4 and has emitter built in
🙂have done alot of research and I have calibrated it correct now and the difference is NIGHT AND DAY!
1.firstly you need to change to preset mode *standard* and enter manual settings as per chart below
http://www.tftcentral.co.uk/articles/icc_profiles.htm#the_database2. download the ICC profile to desktop and right click and install.
http://www.tftcentral.co.uk/icc_profiles/benq_xl2420t.icc3. this is the tricky part and it took me a while to figure it out, make sure you follow the last part EXACTLY as it says, you need to go through the advanced dialog box TWICE so the tickbox is un-greyed.
To apply an existing ICC profile (an ICM file created by some calibration process), do the following -
Control Panel / Display / Change Display Settings / Advanced Settings / Color Management / Color Management (again!) / Devices / select one of your displays*1 / click "use my settings for this device"*2/ if necessary add the applicable profile to the "Profiles associated with this device" box using the "Add" button (if your profile is not already listed but is available somewhere on the network or computer) / click on the correct profile in that box and click "Set as Default Profile".
*1 the CM dialog boxes don't label your displays the same way as other dialog boxes, they seem to lose the manufacturer and model number info that is available elsewhere, so your ABC model nn display comes up as Display: 1. Generic PnP monitor . Also note that at least on my system, display '1' was in fact display '2' in other display settings dialog boxes, and vice versa.
*2 You would think that selecting "Use my settings for this device" would mean the Windows would use your settings for that device (display), but apparently it doesn't. It means ... well, I don't know what it means. Perhaps it means if you don't select it, even the next step (below) won't help you.
2. ENABLE CALIBRATION LOADING BY WINDOWS
Here's the hidden bit of help file...
To enable or disable calibration loading by Windows , you must be logged on with a user account that has administrative privileges.
1. Click to open Color Management.
2. Click the Advanced tab, and click Change system defaults .
3. Click the Advanced tab in the Color Management - System Defaults dialog box, and do one of the following:
To enable Windows to load display calibrations, select the Use Windows display calibration check box.
To prevent Windows from loading display calibrations (disable ICC profiles), clear the Use Windows display calibration check box.
Click Close in the Color Management - System Defaults dialog box.
Click Close in the Color Management dialog box.
Not only is it obscure, it is confused further by the fact that you are back in the same dialog box twice, but the second time it is labelled Color Management - System Defaults instead of Color Management as it was the first two times. But only on the second time is the required box enabled to allow you to tick i.e. it's a system wide setting. Easy to miss.
try it out you will be very pleased with results
