GPU scaling doesn't add lag, and you shouldn't need to trick it. If you have both 1920x1080 @ 144 Hz and 1280x960 @ 144 Hz defined in CRU with display scaling set in the NVIDIA control panel, then 1280x960 @ 144 Hz should never be scaled unless the driver is broken.

while the games still run at the proper 1280x960@ 144hz the weird auto detecting(NOT VSYNC) of refresh rate puts khz @ 157 instead of 140 that's set in CRU when using LCD reduced timings,
while games that allow me to force refresh rate to 144 via in game menus or launch options run at 140khz/144hz according to my monitors OSD & on the 2 games in question that both auto detect have it set to 157khz/144hz.
The horizontal kHz is the total number of lines per second, so of course it's going to be higher if 1280x960 is being scaled to 1920x1080. Games like that usually use the desktop refresh rate. 157 kHz matches the horizontal scan rate for 1920x1080 @ 143 Hz with "LCD reduced" timing. Sounds to me like the game is actually using 143 Hz and your monitor is misreporting it as 144 Hz. This shouldn't happen if you define 144 Hz for both 1280x960 and 1920x1080.

CRU doesn't implement borders because AMD's driver ignores them, and the effect of having borders would be the same as setting GPU scaling to center.

So you have already tested it,that's why it didn't work when i tested on AMD
What about nvidia,it works with that?
I edit byte 15 and 16 of the 18 bytes (0 to 17) of the detailed timing descriptor and edit the checksum byte of the EDID block,is this correct?
GPU scaling works good only for certain resolutions,i need it for a 4:3 CRT monitor,i set a 4:3 resolution and from that i get the 16:10 and 16:9 version without changing the video timings and so without having to adjust the geometry again.
Can you add GTF to CRU?

Despite changing settings on the TV, the EDID continues to report incorrect values. I've used your utility to override the EDID, but the NVIDIA drivers are still reporting the incorrect settings from the TV's EDID.
What audio options are you trying to correct? What are the incorrect values? Where does NVIDIA's driver report the settings?

The driver only reports the settings in the regular Windows sound control panel. Since I posted this, the driver is now reporting my settings of Dolby Digital and DTS Audio under "Supported Formats" (previously it showed the TV's defaults of Liner PCM, Dolby Digital+, and DTS+). However, it is still only reporting 2 speakers attached instead of 5.1 as specified.

Quote:First, it's not possible to add 2560x1600 @ 50 Hz as a standard resolution, and you don't need to anyway because it's already defined as a detailed resolution twice. You only need it once.

Thank you for your detailed answer.
The weird thing is, CRU doesn't let me to add 2048x1536 or 1600x1200 in any refresh rate.(50 hz- 25 hz) I even tried to change clock speed.

Quote:Second, according to your attachments in that thread, you're using a portable device with an Intel Atom x5-Z8350 processor. I don't know if the built-in GPU supports pixel clocks greater than 165 MHz, which is required for 2560x1600 @ 50 Hz. The driver might be crashing because it can't find a usable resolution, but that would be a driver bug because it should at least provide a lower resolution instead of crashing.

Yes it is a LattePanda maker pc with LVDS&HDMI output. According to manufacturers data it supports 4K x 2K (3840x2160) @ 30Hz or 2560x1600 @ 60Hz 12 EUs inside (Up to 700MHz) with triple monitör support. Yes, the driver crashes thus I tried to add display adapters list of modes data 2560x1600 without success.

Actually I borrowed another mini itx motherboard with intel hd 500. The device couldnt either wake up the monitor but never crashed this time.
Thanks to VGA output so I could see what happens there. Intel driver can find the monitör but not the refresh rate so it sets 0 hz.

What I have done to succeed is installing Intel Hd 500 driveer manually. Now the monitör Works with mini itx computer.

When it comes to Lattepanda Pc with Intel 400 display adapter, installing the driver manually didn't fix it.


Quote:Third, CRU requires a driver that supports EDID overrides. I don't know if the driver for that GPU supports EDID overrides. If it does, try adding 2560x1600 @ 30 Hz to keep the pixel clock under 165 MHz and see if that shows up. Then try importing the hdmi.dat file to fix the extension block: https://www.monitortests.com/hdmi.dat

I'm not sure if I understand this(EDID overrides) correctly. I will try to find some instructions. Thank you again
